Transmission general data
The first Honda CVT transmission named as M4VA (Multimatic) was designed in 1995 for Civic with engine 1.6 liters and had been installed on American models of Honda until 2000. In 2000 this CVT was slightly updated and renamed as MLYA, but after a short time a new modification under the name SLYA was released and installed not only on American Civic but also on Honda City. The modification SLYA didn’t have typical problems of the predecessor and this CVT had been produced from 2002 until 2005 for Civic with the engine 1.7 liters. To this day SLYA is installed on 1.5 liter Honda Fit.

Technical issues and repair guidelines
The belt is the main spare part which specifies the lifespan of this gearbox. In terms of design, this gearbox is very similar to the RE0F06A equipped with a push belt. The chain gets strained and and side teeth wear down. Timely detected problems with the belt allow saving surfaces of shafts and only to replace the belt. As with all pushing belts, it is crucial to set the right direction of the belt during the assembly operation, otherwise the owner will soon have to order a new CVT.
The overhaul of this popular and rare (in repair) CVT is usually accompanied with order of the following spare parts:
- Filter cassette
- Filter in the pan
- Pan gasket

The 6-speed transmission JF613E with transverse mounting was produced by Jatco in 2006 for FWD Mitsubishi cars with engine capacity from L4 2.0 to V6 3.5 liters. According to Jatco, this heavy-duty transmission can transmit the torque up to 330Nm. The JF613E unit competes with Aisin's TF80SC, but Jatco transmission is considered to be less complex and cheaper, and when taking into account parameters of reliability and endurance with American 6T45 and Korean A6MF1.

Transmission fluid is changed after travelling 50-60 thousand kilometers without waiting for scheduled replacement of worn-out spare parts (rings and bushings).The torque converter is repaired in the course of the overhaul. The overhaul also requires Kit of gaskets and seals, complete kit of frictions, and less often kit of steel discs.
The main source of problems for all modern 6-speed automatic transmissions is related to the valve body and solenoids.Settings of the JF613 control unit do not allow excessive loading of solenoids. This gearbox as well as Aisin's 4-speed transmissions use forced locking of the torque converter starting at the 4-th gear (that has a positive impact on the transmission durability). Thanks to this feature JF613 may be called "invincible".
“Active locking” and “auto-neutral” features implemented in JF613E are considered to be the pride of Jatco. Both options improve acceleration characteristics, fuel consumption, driving comfort, driving uphill, but at the expense of the friction lining locking wear-out in the torque converter, leading to quicker ATF contamination. Planned repair for this transmission is not complicated and it is required in case of high mileage. The repair helps to prolong service life of this transmission for a long period of time.

Technical issues and repair guidelines
In the process of major repairs, it is required to change the friction clutch of the torque converter lock-up. CVTs produced after 2007 turn out to be reliable (for CVTs) under the condition of proper usage and operates for 150-200 thousand kilometers with a low number of visits to repair services. It is one of the most reliable CVTs around the globe. Common spare parts usually include belt, step-motor (stepper), shaft bearings.
Spare parts of the first priority include:
- seals of the pump, axle shafts (left and right)
- Pan gasket
The step-motor ("stepping" motor of the gear ratio adjustment). The electric drive regulates the space between cones and gear ratio of CVT. Early breakdown of the step-motor is related to the overheating or CVT resource exhaustion. This issue comes from the RE0F06A and it is typical for JF011.
One of the most common reasons for getting into repair services for this transmission is related to the oil pressure shortage connected with improper working of worn-out valve of the high-pressure pump. In many cases, it is required to replace 4 bearings of input and output shafts. The issue is caused by overheating and critical wear-out of the belt, forcing solenoids to apply maximum effort on pressing the belt to cones. One of the most popular spare parts for JF011 units is a metal push belt RE0F010А (Bosch). Timely replaced belt preserves the surface of cones.
Solenoids with exhausted resource are also common for replacement. Some solenoids are interchangeable with other Jatco CVTs. But there also can be some differences with CVTs of Mitsubishi and Dodge. Another typical problem for the RE0F10A (RE0F06A) unit is related to the depress valve. This problem leads to oil starvation in CVT units. In the pump, the valve is replaced by the new one of a larger size. The service life of this CVT and the car itself is estimated by wear-out of cones. Surfaces of cones are considered to be the most important resource of CVT. The price of new cones with replacement service sometimes is higher than the price of an “old” car.

Transmission general data
The 5-speed automatic transmission FNR5 (FS5A-EL - Mazda, 5F27E - Ford) was designed in 2004 on the basis of the 4-speed automatic transmission 4F27E. This unit has several new elements, some upgrades in the valve body and settings of the control block for better acceleration characteristics, fuel saving and increase of smoothness in gear shifting. Since 2005, this transmission has been installed on FWD Mazda 6 (3-8) and Ford Fusion with the engine capacity from 2.0 up to 2.5 liters.

Technical issues and repair guidelines
A typical soft spot of this automatic transmission family lies in the combination Drum Reverse + Rear cover. Aggressive driving style leads to the Overdrive clutch burning. Another typical problem of the 4F27E transmission occurs in Mazda cars, namely, wear-out of the servo mechanism seat of the band Overdrive. This problem is caused by vibrations from operation of the worn-out drum brake band. This chain of malfunctions includes different minor problems like wearout of teflon rings located between this drum and the support of the cover, which are replaced during each overhaul even if these components have no indications of damage.
Valve bodies of this transmission for Mazda and Ford are different. The valve body for Mazda has two solenoids of the main pressure EPC (А and В). The most common problem of all present-day automatic transmissions is related to contaminated ATF clogging the valve body, that in chain order leads oil shortage in packages and burning of friction elements. Frictions in this transmission may serve quite reliably together with other spare parts and solenoids for 200 thousand kilometers and even more, under the condition of well-timed ATF change, filter replacement, and avoidance of frequent forced accelerations. The valve body requires standard cleaning and replacement of spare parts.
Traditionally, Mazda's torque converter quite early requires repair or replacement of worn-out friction lock -up simultaneously with cleaning of the valve body and replacement of the pressure solenoid. The lack of locking, unusually rapid contamination of ATF and leaks through the seal near the torque converter may be considered as the sign of repair necessity for the torque converter. Operation with the worn out torque converter leads to vibrations on the shaft of the oil pump and cranking of the pump bushing (at the first stage of wear). This problem also has a negative impact on the pump seal.

With regard to clutch packages this automatic transmission is well balanced. These packages work properly during their lifespan. Problems are mainly related to wear-out of seals leading to oil shortages and problems with transmission components.The pump assembly is also replaced under the condition of a long-term operation with worn-out torque converter clutch and subsequent vibrations. Contaminated oil speeds up ageing of the pump and bushing. The pump bushing and the seal are the first to get out of order because of above mentioned problem.
Worn-out bushings are repaired and replaced quite frequently. Then the list of parts to be replaced includes the drum with a sun gear and the brake band. As far as the electrics of this transmission is concerned, speed sensors of the input and output shafts are the first to reach the end of their service lifespan. Solenoids Shift are standardized in all valve bodies. These solenoids operate properly for quite a long time, Solenoid-electric controller EPC (VFS) is the first to get out of order because of high loads.

This 4-speed automatic transmission has two modifications. The modification F4A51 was used cars with engines capacity from 1,3 up to 1,8 liters. The modification F4A52 was used for more powerful engines. In terms of design, these transmissions are similar, but at the same time some elements in one transmission are larger than parts in the other one. This automatic transmission was installed on Japanese cars Mitsubishi Galant, Lancer and Korean cars Hyundai Serato, Santa Fe and Sonata. Subsequently, the transmission found application in different American and Chinese mid-size cars. Later this transmission was upgraded and a maximum engine torque was increased. It should be emphasized, that the F4A42 unit gained a good reputation. Thanks to simplicity of its design, this transmission is notable for reliability and durability. Its not a surprise when after running 300.000 kilometers this transmission does not require the overhaul. However, the service lifespan of this transmission also depends on operating conditions and the driving style of the car owner. This transmission is very sensitive to abrupt accelerations and is mainly intended for operation in urban areas.
In order to simplify the repair procedure of the F4A52 system, it is required to use special repair kits, which help transmission specialists to fix any malfunctions. Pump and seals are the main soft spots in this transmission. In specific cases, problems may occur in the valve body. The valve body damage usually leads to expensive and time-consuming overhauls.

Transmission general data
The 4-speed automatic transmission F4A41 / F4A42 from Mitsubishi was designed in 1997 for FWD vehicles of the middle class with engines (1.3 - 2.8 lit.). This transmission was strongly influenced by Chrysler. In terms of design, this range of transmissions is more related to А604, then to KM series. The F4A41 unit is installed with engines 1.3 - 1.8 lit., updated modification F4A42 for engines 1.6 - 2.8 lit F4A41-42 has been used since 1999 on many well-known FWD cars of middle class with engine capacity about 2 lit. The W4A42 is a rare version on the basis of FWD automatic gearbox for 4WD light motor vehicles.

Technical issues and repair guidelines
This Mitsubishi-Hyundai family of transmissions is frequently repaired. The distinction between F4A41 and F4A42 units lies in distinct quantity of frictions in packs, and consequently clutch drums of various capacity. The transmission reassembly commonly requires the kit of gaskets and seals, filters and complete kit of frictions. In old cars which went through the oil starvation, specialists change the entire kit of bushings together with usual procedures related to cleaning and reassembly.
In terms of design, the main soft spot of the F4A41 unit is the planetary gear Overdrive, where the needle bearer gets dyed when exposed to overloading. The rear planetary gear and a crown gear also get out of order. This planetary gear was repeatedly updated. In most cases, specialists replace burnt Overdrive package, frictions with steel and bearing discs. The valve body is one of the causes for burning of packages Underdrive and 2-nd Brake. The wearout and clogging of valves and solenoids leads to fluid shortages not only in these packs, but also in the TC unit. The valve body was repeatedly updated and now has modifications with 5 and 6 solenoids.

Technical issues and repair guidelines
Overhauls of these transmissions are triggered by two main reasons: fluid leakages via the damaged pump seal and issues with gear shifting. Generally, the leaking pump seal is a sign that the torque converter (TC) has been operating with a worn-out lock-up and vibrations for a long time leading to the damage of bushings and seal. Overhauls of these transmissions are usually performed when the car reaches high mileages and consist of reassembly and repair of the TC unit and filter replacement. Specialist always perform the repair of TC, valve body reassembly in half of the cases with check and change of solenoids and wiring. It is also required to replace brake bands if the transmission operates for a long time with burnt fluid. The long-term operation with worn-out torque converter may lead to the damage of seal and pump bushing. As a result, the pump bushing may be replaced. Vibrations may have a negative impact on the pump, therefore specialists have to order a complete kit of bushings for these transmissions.
Overdrive frictions are frequently replaced. Specialist assume that the main reason is related to poor design of an old O.D. piston. In new modifications, this piston has an updated configuration. Usually Direct-Forward ffrictions wear out because they are highly loaded. Solenoids are quite reliable, but when problems occur they are mainly caused by circuits of solenoids (solution –cleaning of contacts). The design of this gearbox is similar to the KM170. After proper reassembly, these gearboxes easily operate for several years until the next overhaul.

Ford had been manufacturing a budgetary Aspire equipped with the F3A until 1997, when 3-speed automatic transmissions were ousted from the market. It’s a very rare case when the F3A transmission gets in repair services. Spare parts for repair of this transmission are only kits of gaskets and seals and kit of bushings. The open filter with a metal lath gets replaced quite rarely, in most cases it is just washed for reasons of economy.

The 4-speed automatic transmission CD4E has been used since 1994 on well-known FWD vehicles with engines 2.0 - 2.5 liters of Mazda such as 626, Tribute and MX6 (LA4A-EL). Ford used this transmission on the Probe, and later after some updates on Mondeo, Escape and Fiesta (named as the 4F44E according to a new Ford classification).This transmission became quite competitive according to the ratio price/quality and had been used until 2007 (was in production for 13 years).

Technical issues and repair guidelines
Experts assume that the design of the CD4E transmission is not good enough for 3 liter vehicles and profitable for repair services. This is due to the fact that CD4E is installed on long-living and unique vehicles, and also that this transmission is repairable and after some minor repair it operates for a long time. It is considered to be an American version of the 5HP19 transmission (on BMW-Audi-VW).Each overhaul of this transmission is accompanied by replacement of the filter. The filter has a felt membrane. ATF is changed every 60 thousand kilometers. The electrical part in the CD4E is considered to be simple and reliable. In some cases, transmission specialists only have to replace worn out block of solenoids.
One of the most vulnerable and repairable components in this transmission is a double drum, (clutch basket) Forward/Direct (6 Cylinder). Friction components and steel discs of both drums get replaced in the process of the drum repair. It is recommended to check the bushing of this drum together with steel and cover plates. This bushing is the 1-st element to get worn-out and requires replacement to prevent vibrations and losses of oil pressure.
Another common problem is the pump shaft failure caused by overloads. The oil pump often gets out of order when metal pieces appear in gears. The rubber of pistons rapidly wears out because of oil starvation and overheating. The kit of bushings is commonly ordered for repair of the CD4E transmission. Worn-out bushings in this automatic transmission is the sign of oil shortages and abnormal dynamic loads. In terms of design, the Forward planetary gear is considered to be another soft spot of the CD4E transmission. This planetary gear cannot endure ultimate loads from the engine. The reason is related to the bearing failure.
Torque converters of the CD4E are quite sensitive for such engines. One of the most frequent problems is the wheel hub bushing wear-out. The problem is related to insufficient oil pressure, overloads and overheating. The torque converter preventive repair should be performed in the course of the first overhaul after travelling 130-150 thousand kilometers. One more issue characteristic to the “old” CD4E transmissions is related to wear-out of the differential “teeth”. It is advisable to check the differential condition during the overhaul and reassembly.

Transmission general data
Honda transmissions differ completely from the rest of automatic transmissions, because Honda does not use planetary gears. Honda transmissions are not complex in terms of design, have larger dimensions and as a result considered to be more robust. But automatic transmissions produced by Honda also have some vulnerabilities related to electronic gear shifting control: friction discs, solenoids, and the valve body.

Because of this, many car owners neglect basic maintenance services such as ATF quality control and timely replacement of the filter. Subsequently it results in clogging of valves in the valve body and solenoids, oil starvation and rapid wear-out of sealing rings, frictions and bushings. 300-400 thousand kilometers is considered to be a standard mileage before the first overhaul for these Honda transmissions.
Repair procedures
The torque converter (TC) is the first component to be repaired in Honda automatic transmissions. A major repair with reassembly starts with change of transmission fluid and replacement of a metal filter. The main external filter is usually installed by specialists on old transmissions.The repair of this family of transmissions with the filter is performed with the help of ordered repair kit of gaskets and seals with friction elements and steel discs. Friction elements are frequently replaced separately and steel discs as a full kit. Masterkit is the fullest repair kit of friction elements and steel discs with kit of gaskets.
Honda friction components usually operate for a long time, but after exhausting an enormous resource of frictions (above 300 thousand kilometers) or when these elements are soaked with burnt oil, then the change of all frictions would be the best option.Worn-out switching solenoids of linear pressure and the clutch lock-up solenoid are commonly replaced during repair procedures. The design of solenoids includes anodized plate element, which is likely to wear. This component is changed after running over 200 thousand kilometers.

Transmission general data
The French automaker PSA (Peugeot Citroen Association) in collaboration with Renault launched the mass-production of the 4-speed automatic transmission DP0 (also named as AL4) in 1999. The automatic transmission AL4 is intended for a FWD vehicles with engines from 1,4 up to 2 liters. The automatic transmission AL4-DP0 is a unique and successful solution of French engineers. The design of this transmission is very simple and well-balanced according to the principle «nothing extra».

Technical issues and repair guidelines
The DP0 unit has a heat exchanger for oil cooling. All transmissions with the heat exchanger operate at a temperature close to critical. In summer time, the DP0 regularly overheats and has some problems with the electrical components, namely with the valve body. It is a constructive peculiarity of many automatic transmissions with the heat exchanger. After running 80 thousand kilometers its up to the auto owner to preserve this transmission from overheating. Friction components contaminate ATF, the dirt settles in the heat exchanger (which also operates as a filter) and as a result after critical contamination of the heat exchanger the oil does not have time to cool in case of the hot weather. Therefore, the valve body (and solenoids) start operating improperly. The more contaminated becomes the fluid, the higher the operating temperature and the lower efficiency of the valve body.
The resource of this transmission before the overhaul (under the condition of careful and proper usage) may reach 150-200 thousand kilometers after well-timed repair procedures with reassembly and replacement of spare parts. After these procedures the transmsision resource may be prolonged up to 500 thousand kilometers.
Soft spots of PD0
EPC and TCC solenoids are the most frequently replaced components of the DP0 transmission. Worn bushings are also often replaced by transmission specialists. The wear-out of bushings leads to the following chain reaction: bushings start leaking, packages do not have enough oil and the computer forces the ЕРС solenoid to open the channel to the full cross section, the pump operates under maximum load and the EPC solenoid rapidly wears. The operation with fluid shortage has a bad impact on friction components of the corresponding package. The valve body is a typical area for repair. The valve body is very sensitive to overheating and contaminated ATF. Overheating changes the metal plate geometry, valves wedge and springs become overloaded until they break down.
Oil losses through worn-out joints lead to the pressure drop in the line, slipping and burning of friction components. The wear-out of one-sided friction discs occurs evenly, therefore all friction discs are replaced during the overhaul. Specialists recommend to replace Teflon rings of the rear cover. Brake bands (the pair F2 and F3) are replaced in the process of each overhaul of the transmission with burnt ATF. Servo pistons are replaced together with brake bands. The damaged pump cup (seal) is the most popular part for repair among seals and sealing strips. One of the most common problems takes place in the needle bearing located between the hub 570 and drum 554 in the Е2 package . The clutch package E2 (4th) is the most popular part for replacement among spare parts.
