But it is not because these transmissions are extremely reliable and durabile, but on the contrary, once these transmissions get damaged by overheating, they should be replaced rather than rebuilt. Typical problems of these automatic transmissions (from AOD-E to 4R70W) include the following: wear-out of seals and rings, that results in oil pressure drop in clutch packs, oil overheating caused by the pressure shortage, clogging of the valve body, wear-out of the brake band and backlash of servo pistons, wear-out of the torque converter locking and backlash of the pump shaft with wear-out of seals and bushings, ageing of rubber and plastic elements. Owners of this automatic transmission have to change oil and filter every 30-50 thousand kilometers, perform the torque converter repair, install additional transmission cooling system, and when having the slightest suspicion regarding shortages in oil pressure, it is necessary to visit the nearest repair shop. A typical overhaul of the "old" AOED transmission, except spare parts, includes the following: Kit of gaskets and seals \ Overhaul kit. Since 2003, transmissions of the 4R70W/4R75E/W series mainly have been delivered to repair shops.

Transmission general data The 5-speed automatic transmission AW55-50SN was developed by Aisin specialists at the end of the last century as an exclusive 5-speed automatic transmission for non-Toyota FWD vehicles with engines from 2 up to 3 liters. After update of the valve body and computer settings, this transmission as AF23 and AF33 was installed on GM models: Daewoo-Chevrolet (Captiva, Epica, Laketti ...), Saab, Opel and American Saturn and Suzuki. The testing of this unique transmission was performed since 2000 on Volvo cars (on C70, both the 40, 70 and S60s and S80s). Part of the design solutions for this tranmsission are adopted from its successful predecessor - the 4-speed AW50-40. The transmission was so successful that even its competitors installed AW55 for their popular cars, simultaneously releasing their RE5R05A (JR507E) (Nissan-Jatсo) and 5L40E / 5L50E (GM-Europe). Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type5ATFWD3307,13,5Type T-IV Technical issues and repair guidelines The torque converter repair after running 200 thousand kilometers is a routine procedure. Repair kits of gaskets and seals for this transmission are produced by many manufacturers. Frictions are replaced by whole packages. Packages of clutches and brakes are designed in a fairly balanced manner and wear out at about the same time. The complete kit of frictions is also ordered when linings of remaining (unburned) clutches are soaked with burnt oil.The most popular parts for replacement are the pump seal and the pump cover bushing. The first problem occurs when operating in the oil starvation mode and with the wornout torque converter. Almost each overhaul is accompanied with the torque converter cutting and its subsequent rebuilding. The lock-up friction lining wears out quite rapidly causing many issues in the AW55-50. There are many signs of the faulty valve body, but the reason for the majority of premature (before 150-200 thousand kilometers) problems of the mechanical components in this transmission lies in insufficient pressure of the ATF coming from the valve body. Dirt in the ATF and high temperatures, wear out and clog channels of valves and solenoids of the valve body. Worn-out areas are clogged with dirt and plungers get wedged, so the ATF does not reach clutch packages and the torque converter lock-up.The valve body repair and cleaning should be performed as early as possible (when you notice the first signs of improper operation) in order to avoid typical and fatal problem, namely the valve body housing wear-out. For rebuilding of transmission units in "old" cars, specialists usually order the kit of frictions, steel discs, and repair kit of gaskets and seals (overhaul kit). At the same time specialists replace the brake band (because friction linings are soaked with burnt oil). The pressure shortage from oil, coming from clogged valve body may have a negative impact on bushings. The pump cover bushing is the first to wear out. In rare cases planetary gear bushings are pressed out. Mechanical elements of the AW55-50SN transmission are very reliable or even may be called “flawless”. The evidence of reliability lies in the factor, that for 90% cases of transmission components repair, specialists order only the repair kit of bushings. But if a driver frequently overloads the transmission, then repair specialists sometimes have to rebush or replace worn-out rear planetary gear.

Transmission general data The 4-speed hydraulically controlled automatic gearbox AW50-40 produced by Aisin Warner was designed in the 90-s for well-known "family" vehicles of the middle class with 2-liter engine: Renault Laguna, Volvo (С70), Saab, Opel. This gearbox is also installed on KIA and Daewoo. This gearbox can be easily identified according to the pan form. According to GM classification, this gearbox is known as AF14 (AW50-40LE). The AW50-40LE version has enlarged hubs, drums, overrunning clutches, planetary gears, in order to transmit higher torque. In 1998, the new modification AW50-42LE (AF22) was released in order to expand the usage of this gearbox for engines with the capacity up to 3.0 liters. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type4ATRWD25012,56Type T-IV Technical issues and repair guidelines In addition to the filter replacement and torque converter rebuilding, overhauls usually require repair kit of gaskets and seals (Overhaul kit). Besides the repair kit of gaskets, specialists also order a complete kit of frictions. It is especially needed in situations when burnt ATF from Direct and Forward frictions reach easily wornout frictions of other packages.The complete repair kit Masterkit is frequently ordered for a full reassembly of this tranmsission. Typical repair areas in AF17 - AF22 (AW50-40, AW 50-42) This gearbox is quite sensitive to ATF cleanness and as the filter is replaced in case of the gearbox disassembly, then old cars are provided with a cooling line of the magistral main filter. Typical problem of old AW50-40 components include the following: drum (Forwad/Direct) – wear-out of the fitting area, cracks in the welding joint area. This problem leads to burning of frictions and steel discs of this drum. Forward and Direct packages are replaced more frequently than others. Steel discs also get burnt in the abovementioned packages.The brake band is another component which is replaced in the process old cars overhauls in addition to replacement of spare parts and frictions. This band is also included in the list of recommended spare parts in case of burnt oil. Improper operation of the band in addition to kicks in the process of gears shifting also leads to rapid wearout of the drum Underdrive - С3. The friction lining wears out unevenly leading to bushings beating and wear-out of pump units. Non-operating or worn-out torque converter lock-up leads to clogging, ageing and wearout of valves of the valve body and solenoids. If the gearbox operates for a long time with this problem, then shafts and pump get overheated, operate without oil, and as a result of vibrations overheat and damage bushings.Seals of the pump and semi-axles are replaced during each visit to repair services. If the problem with leaking seals and damaged bushing is neglected, then the whole pump is replaced. A common reason of all issues related to the oil pressure loss lies in malfunction and contamination of the valve body or solenoids. Usually this problem is related to large wear particles in ATF and the faulty torque converter. Specialists like this gearbox for its reliability and simplicity. It operates during the whole lifespan of the car in which this gearbox is installed. But it is required to monitor the oil level and its cleanness, otherwise negligence may lead to pressure losses in the line and wear-out of bushings, spare parts and damage of bearings, that results in the necessity to perform the overhaul.

Transmission general data The 4-speed automatic transmission AW60-40LE was designed by Aisin Warner in 1995 for FWD vehicles (Suzuki, Opel, Daihatsu, Fiat) equipped with engines up to 1.6 liters. After testing on Suzuki Estima, this transmission was widely installed on numerous models of different brands. According to GM classification AW6040LE is known as AF13.

In addition to the filter, during the overhaul transmission specialists usually order the following: -Repair kit of gaskets and seals - Complete kit of fricion plates -For the reassembly procedure specialists also order the kit of steel discs In many cases, the main problem lies in two burned clutch packages: Forward and Package 3-4 (friction clutches and steel discs of packages Forward and 3-4).The brake band is ordered together with the kit of friction clutches. When the burnt oil comes to the friction linings, they start operating with noticeable jerks or slippages. The kit of 4 plastic washers of supporting bearings is replaced during the overhaul of ageing transmission.With regard to electrics, typical problems occur in valve bodies. Valve body units should be reassembled and cleaned in the process of each overhaul. Transmission repair specialists also should replace the gaskets. The solenoid “shift” (gear shifting) is frequently replaced because of the end of service lifespan. The solenoid of the torque converter lock-up is also often replaced. Together with two above mentioned solenoids specialists replace the solenoid-electric controller EPC/SLT (main pressure).The reason for premature wear-out is assumed to be a long-time operation in contaminated and overheated oil with the worn-out torque converter lock-up. The valve body usually is quite durable, but aggressive accelerations and driving with worn-out friction clutches may bring closer the replacement time. If there is smell of burning oil, then in most cases the problem lies in packages the Forward and 3-4. Generally, the family of automatic transmissions AW60-40LE is considered to be maintenance-friendly as the majority of 4-speed Aisin transmissions. Thus, after the diagnostics and replacement of all worn-out parts it can operate for a long period of time.

Transmission general data The 6-speed automatic transmission А960Е with longitudinal positioning was designed in 2005 by Aisin Co for rear-driven Lexus cars (sedans GS300, IS250 and IS300) with 2.5-3 liters. It also operates on right-hand Toyota MARK X. This transmission is developed on the principle of modules on the basis of the 5-speed A750 transmission together with 6-speed A761, but intended for a lower torque (190-300 Nm). The main competitor of this transmission is ZF6HP19-21. According to Aisin Co classification, this transmission for Lexus can be named TB-65SN. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type6ATRWD3148,54,1Toyota WS Technical issues and repair guidelines Frequently used sports mode of this transmission quickly leads to the wear-out of the torque converter friction and fluid contamination. If the piston friction turns out to be worn-out, then some glue components reach the fluid, that makes some instant negative impact on the valve body functionality. Contrary to the 6НР19 unit with the torque converter having several double-sided frictions for the slippery mode, the A960E transmission has a single friction glued to the piston, that requires monitoring of the wear-out and when having any suspicions related to lack of the torque converter lockup, therefore well-timed diagnostics and spare parts replacement procedures should be implemented. Typical overhaul of А960Е requires replacement of the following parts: - Kit of gaskets and seals, without pistons. After burning of frictions they are all replaced with rubber seals. The contaminated fluid leads to wear-out of teflon rings. If these rings wear out, they start contaminating transmission fluid. - Kit of frictions, which are replaced in most cases. - Kit of steel discs which together with friction discs and repair kit of gaskets represents the complete repair kit (Masterkit). Complete and timely replacement of spare parts in this durable transmission adds up to 70% of increased resource before the overhaul. - The pan gasket is ordered each time when changing the ATF and removing the pan for the filter replacement. The valve body repair with replacement of solenoids always implies the torque converter rebuilding. The torque converter spare parts are the first to exhaust their resource.One more problem that may be caused by vibrations from worn-out friction of the lock-up mechanism that damages the pump seal and bushing itself. The typical soft point of this transmission is the oil pump unit with leaking seal, and if it is neglected the problem spreads to the pump bushing. Further driving without timely repair of the torque converter leads to the loss of the pump itself. It is often accompanied by wear-out of the torque converter lockup solenoid. Electrics in А960 The rebuilding of this old А960 unit includes the replacement of the linear solenoids. Selection of solenoids for the А960 unit is performed in accordance with VIN-code of the car. The peculiar feature of this reliable 6-speed automatic transmission is that the driver does not receive any noticeable signals related to the necessity to replace worn-out spare parts (the torque converter friction and solenoids which can not endure aggressive accelerations with the "slipping mode" of the torque converter clutch).

Transmission general data The automatic transmission A6LF1 is a part of 6-speed transmissions family (A6LF2/3, A6GF1, A6MF1 /2) produced by Hyundai. This transmission is an expensive and comfortable alternative to the 5-speed automatic transmissions A5HF1 (A5GF1). These transmissions had been tested since 2009 on a limited series of Hyundai Avante HD\MD and after 2-3 years of modifications were installed on luxury FWD and AWD cars Hyundai (Sonata, Opirus...) and Kia models with engine capacity from 1.4 up to 3.8 liters. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type6ATFWD/4WD3237,84SP-IV Technical issues and repair guidelines Aggressive accelerations and critical overheats may lead to replacement of rings and valve body gaskets. After covering over 150 thousand kilometers replacement of the whole repair kit is considered to be a routine procedure. The aim of this measure intended for protecting solenoids which have to deal with higher loads caused by increasing oil leakages through sealings. The main signs of the problem are the following: wear-out of the torque converter lock-up, rapidly contaminating transmission fluid, and issues with gear shifting. The valve body disassembly usually indicates critical contamination and sticking of valves. Insufficient oil pressure (caused by problems with the valve body or leaks of ATF through rings, jointing edges and as a result wear-out of solenoid valves) in most cases leads to burning of friction elements with Overdrive and Underdrive discs, but often drivers neglect this problem, resulting in replacement of all friction clutches and steel discs which operated in burnt ATF. Contaminated ATF from this package damages corresponding valves and solenoids of the valve body. The vulnerability of the A6MF1/2 transmissions resides in burning of clutches 3-5\R and 2-6. For replacement of these burning packages, Hyundai released the kit of "Power Pack" friction elements with steel and bearing discs.The Overdrive is also frequently replaced by repair specialists. The problem is explained by overloads caused by contaminated fluid, resulting in wear-out of teflon rings on the rear cover and pressure losses in packages.A typical problem for Hyundai differentials is related to damage of splineways of the differential body under the condition of longtime and frequent wheels slippages. During the first years of testing, the main problem lies in the valve body and solenoids (problem identical to ZF transmission ZF6HP from which the valve body operation principle was adopted). The most failure-prone solenoids are the following: 1. EPC solenoid 2. TCC solenoid. 3. Shifting solenoids Another frequent problem for this transmission (as well as for other 6-speed automatic transmissions) is related to the torque converter clutch wear-out. The more often drivers use aggressive accelerations, the closer this transmission to the repair shop. The valve body may be considered a soft spot in the electrical part of the A6MF2 \LF2 transmission. As in all 6-speed automatic transmissions, the A6LF1 valve body is very sensitive to overheating and contaminated ATF, which first of all may be provoked by wear-out of the torque converter friction and clutch packages and in chain order lead to (pressure shortage from solenoids and the valve body) more rapid wear-out of frictions in packages of clutch and braking. Problems at the early stage are usually solved by repair and cleaning of the valve body and solenoids, opening of the torque converter for replacement of spare parts. In more complex repair cases, transmission specialists have to repalce solenoids.

Transmission general data The 5-speed automatic transmission А650Е with the langitudinal positioning has been installed since 1998 on RWD Lexus (as AW 35-51LS) and for some period of time on 4WD cars such as Land Cruisers and Hilux. This robust automatic transmission had been installed on the RWD and right-handed Toyota produced from 1998 until 2007.

Partly this is due to the fact that this transmission was so-called “pioneer” used for testing new technologies of linear solenoids, increased temperatures and slipping of the torque converter lockup, and partly because all Aisin products with longitudinal positioning are traditionally quite durable. Many units and spare parts from А340 can be used in the А650Е modification. It is a very rare case when all gaskets and seals from the overhaul kit and friction components in 2nd Brake package are changed in the dry-operating А650Е transmission.Occasionally, long-time operation of the transmission with a leaking seal leads to necessity of the pump and pump bushing replacement. This problem is caused by the wear-out of the torque converter friction, where spare parts are untimely replaced. This automatic transmission was replaced by 5-6-speed А750Е and А761Е.

Transmission general data The 6-speed automatic transmission A761E, (A760E -F \Н) with longitudinal positioning is similar to the 5 speed А750 in terms of design. It has been tested since 2003 with 8-cylinder engines of Toyota Celsior and with Lexus LS430. This powerful 6-speed RWD transmission was produced in pair with economical А960, intended for lower torque (200-310 Nm). This automatic gearbox together with А761-А960 are direct competitors of ZF 6HP26 and 6HP19 units. A760E is a basic modification for RWD units, - A760F – for AWD SUVs of Toyota and Lexus, - A760Н – is a rare modification for 4WD light motor vehicles. - in 2006, the upgraded А761 unit was released. It is notable for perfect operational parameters of a new valve body and solenoids.

Problems of the А761 unit are related to already known issues with А750Е. These problems are caused the fluid overheating or its contamination by friction dust. Many experts consider А760 for rear-drive cars to be extremely durable as all Aisin automatic transmissions. Components of this transmission can operate properly for more than 300 thousand kilometers without overhaul, under the condition that they operate with comparatively clean oil. Typical issues in A761 Commonly, together with spare parts repair specialists also replace the package of friction discs, burnt as a result of pressure shortage caused by clogging of the solenoid or valve body. All frictions are usually replaced in case of burnt transmission fluid. When we talk about the most problematic elements in first generations of the А750-А761 family, we should point out relative dependency of electrical components of this tranbsmission (valve body) from from the fluid condition and wear-out of the torque converter lockup. All problems with shifting are usually related to spoilt and worn-out valve body. Therefore, any diagnostics and rebuilding procedures start with testing and cleaning of the valve body and solenoids. All valve body problems start with worn-out elements of the torque converter. The torque converter is repaired as well. Valve bodies for А750, А761 and А960 are identical from the outside. But the internal design, computer settings and solenoids (as well as their quantity) have been constantly modified during testing, therefore selection of solenoids for replacement (as well as valve body selection) is performed according to VIN-code. The number 8870 is displayed on plates of the А761 transmission.The valve body replacement for this unit is relatively rare in comparison with European manufacturers on similar automatics (722.6 and ZF-6HP26). Generally, reassembly and cleaning of the valve body and cleaning-replacement of solenoids are performed when repairing the А761 unit. First and foremost, repair specialists have to replace solenoids. These solenoids have the valve, receiving the main load from contaminated fluid coming from the torque converter. Each replacement procedure of solenoids is accompanied by the torque converter repair and replacement of the lock-up friction.

Transmission general data This 5-speed automatic transmission А750Е\ F produced by Aisin Warner has been used since 2002 for powerful rear- and full-drive SUVs Land Cruiser, 4Runner and Lexus. The А750F (4WD) is the most frequently repaired transmission mated to engines with capacity equal to 4.7 liters. The А750 transmission replaced the 5-speed А650Е from the previous generation and “invincible” А340 series. In terms of design, this transmission is similar to 6-speed А761 and А960 units. The А750 modification can be paired with 1GR-FE (for lower torque) and 2UZ-FE engines in 4WD cars. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type5ATRWD/4WD485124Toyota T-IV Technical issues and repair guidelines This transmission has almost flawlessly matched gear ratio, tested cooling and ATF heating systems. The acceleration in the sport mode turns on slipping torque converter lockup starting at the 3-rd gear. It doubles the time before the torque converter repair in comparison with competing 6HP26 units. The fluid change (Toyota WS) and filter replacement in A750 is performed with the help of partial and full replacement methods. The transmission electrics has delicate settings and sensitive to the oil level. Solenoids of this transmission can exhaust its resource prematurely and often get replaced, especially in gearboxes during first two years of series production. But in general, this transmission as well as majority of rear-drive Aisin automatic transmissions was produced to be "invincible". Typical problems in A750E The most common ordered repair kits for the first overhaul of the А750F unit, includes the following: - Kit of gaskets and seals, Overhaul Kit - Kit of all friction components Overhauls of long-time neglected transmissions are notable for the fact that friction components should be replaced with all solenoids. The first package that gets burnt with cover plates: Forward С1 frictions. Then comes the turn of the В1 braking package.Other frequently burning frictions are located in Direct, C3 and 2nd brake packages. Different problems with the torque converter, valve body and solenoids may occur as a result of long-time overheating or aggressive driving style on the off-road territory or on snow after 70 - 80 thousand kilometers.Transmission operation with worn-out torque converter clutch may lead to vibrations and fluid leakages through the pump seal. At the same time, the problem with the pump bushing occurs, and later you will have to deal with the pump failure. Valve bodies of А750, А761 and А960 have been constantly modified, improving their design, therefore selection of valve bodies and solenoids for replacement is performed specifically for each car according to its VIN-code. In general, the А750F unit is adjusted quite accurately for the torque converter and the valve body. Afterwards, you can drive for 150-200 thousand kilometers without serious problems for car owners, if ATF condition is controlled.

Transmission general data The 4-speed automatic gearbox Ford A4LD was designed for RWD vehicles (Explorer, Mazda pickup cars and many others) with engines from 2.5 up to 4 liters. This family of transmissions is manufactured in Bordeaux, France. After the update in 1995, this gearbox was provided with an electronic control, the letter "Е" was added to its name (A4LD-Е). In 1997, this gearbox became fully equipped with an electronic control unit and changed its name in accordance with a new classification- 4R44E,and after the update of several units, the 4R55E modification was released. Spare parts for repair of these gearboxes are interchangeable. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type4ATRWD9,54Dexron VI Technical issues and repair guidelines The torque converter in these transmissions is the first component to be replaced during repair procedures. In most cases, transmission specialists order the Masterkit repair kit to fix this transmission. This kit includes all gaskets and seals, rings and friction components with discs, except filter and brake bands, which are ordered separately. Repair kits contain all necessary gaskets and spare parts of the valve body, other gearbox components and pan, to replace the old rubber, paper gaskets and plastic of the transmission, which served for more than 10 years. This transmission is handed in for repair after failures of the brake band О.D.\Intermediate and the drum Overdrive. The drum Overdrive is also considered to be a soft spot and gets out of order together with the brake band and Servo piston of the brake band. When solving the abovementioned problems, specialists also replace the brake band piston INTM./ O.D. Vibrations and overheating of this drum may lead to replacement of not only friction elements of the package Overdrive, steel discs, and bearing disc, but also of the pump support.In many cases, packages get burnt because of worn-out pump bushing and insufficient pump productivity. This problem can be detected by means of the leaking seal. The repair of electrical components consists of replacement of EPC solenoids, solenoids shift (4), solenoids of the torque converter locking (TCC), which reached the end of their service life.The valve body often causes insufficient (on bushings) or excessive pressure. The valve body gets clogged with friction dust from the worn torque converter. If the torque converter friction is worn out to the glue layer, then it significantly speeds up the wear-out and clogging of solenoids and the valve body.The most replaceable clutch discs are friction elements of the Forward Clutch package and corresponding steel discs, which twofold outrun the package Direct in sales, other friction elements are replaced more rarely.

Transmission general data The 4-speed automatic transmission A4AF-3, A4BF-3 was designed in 2000 by Hyundai specialists and was supposed to become a successor of the A4AF1 for FWD medium vehicles such as Hyundai Matrix, Elantra, Accent, with engine up to 2 liters. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type4ATFWD1906,34SP-III Technical issues and repair guidelines This transmission is considered to be very reliable, enduring long-time operation with contaminated transmission fluid. After a proper overhaul with spare parts reassembly specialists can give 1-2 years warranty. Many spare parts for A4AF3, A4BF3 transmissions are interchangeable with the whole A4AF family of automatic transmissions.The list of common spare parts includes the following: closed filter with felt, which is replaced in the process of each reassembly of the transmission that covered 150- 180 thousand kilometers; the brake band, which is replaced with the whole set of friction components when smelling the burnt ATF (Brake bands for engines up to 1.8 liters and over 1.8 liters are different), the brake band is replaced with the seal when operating for a long time with worn-out spare parts of the torque converter; in many cases specialists order the kit of bushings for the overhaul. Seal boots are unified and can be applied for all relative automatic transmissions from КМ175 to F4A33, they are ordered during each rebuilding. If seals are replaced, but the torque converter is left untouched, then after a short time the seal will start leaking again and, as a result, it will be required to reassemble the oil pump. Friction elements in the Direct Clutch\ Forward packs burn 3 times more frequently. In most cases, all friction components are ordered for complete overhaul. Another problem of the A4AF1 became a real “headache” for specialists in the process of the A4BF3 transmission repair: the drum gets burnt in each 5-th automatic transmission which comes to repair services, because of worn bushings and consequent oil leakage.Typical design problem of the Overdrive unit lies in damage of bearings caused by side loads from the differential. Specialists often have to repalce the whole set of 6 solenoids and wiring. Even if the problem occurs in only one solenoid, technicians have to replace all of them because of short resource of other solenoids.Sometimes the problem of one of the linear pressure solenoids may lead to harsh shifting or forced actuation of the 3-rd gear without error codes. Problems usually lie in the fact that the solenoid valve wears out the channel because of contaminated ATF, starts hovering and at some moment gets wedged. Cleaning only contributes to the problem and the repair does not cover expenses. Generally this transmission is reliable like Hyundai cars when avoiding unnecessary overloads and overheating.

Transmission general data The 4-speed modern automatic transmission A4CF1 produced in 2005 and its more powerful modification A4CF2 from Hyundai were designed for cars with the engine capacity up to 2 liters. Since 2006, these automatic transmissions can be installed on all FWD small cars of Hyundai (Accent, Solaris, Ceed, Getz...) and Kia (Spectra, Forte, Cerato, Soul...). The first modification A4CF1 had a lot of problems, therefore an updated modification named A4CF2 was released in 2005. Minor changes in electrical parts and computer settings were introduced in 2007 in order to prolong the transmission lifespan that may be comparable with the resource of the whole car. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type4ATFWD16063SP-III Technical issues and repair guidelines Typical problems during the first years of the transmission operation are related to change of ATF and filter replacement. It is recommended to replace all friction components together with the kit of gaskets and seals during the transmission rebuilding. Common problems in A4CF2-\1: The list of the most popular repair procedures for this transmission includes the valve body reassembly and replacement of solenoids. The most vulnerable failure-prone are VFS (EPC) solenoids and PWM solenoids. The problem is related to contaminated and hot (because of the torque converter) transmission fluid and resource wear-out. In many cases problems with electrical parts are caused by faulty wiring of solenoids. Some problems may occur in the pump as a result of a long-time operation with the leaking seal, damaged bushing (applicable to A5HF1) and shaft vibrations.Specialists assume, that high temperatures and forced torque converter lock-up lead to rapid oil contamination and this suspended fluid clogs and wears out channels in the valve body and solenoids, leading to the oil pressure shortage in packages and early burning of friction components. A long-time operation with the pressure shortage and vibrating clutch lock-up leads to problems with the pump and some other unpredictable issues.
