Transmission Diagnostics & Repair

Transmission general data The 5-speed automatic gearbox RE5R05A with the longitudinal positioning was used since 2000 on all powerful RWD models of Nissan as well as on Infinity with engine capacities 2.5 -6 lit. There are a lot of various sub-versions of the RE5RO5A solution for various torque and various types of cars, which are distinct in filters, friction components, steel discs, hard parts, and valve body. All sub-versions are founded on very fail-safe construction of RWD Nissan 4-speed automatic gearboxes, which were modified with the Overdrive planetary gear and more intellectual electronic control.

The main repoair issue of this transmission is caused by aggressive accelerations leading to fast wear-out of the TC locking unit, resulting in wear-out of channels and valves of the valve body. Consequently, the pressure shortage takes place in different packs depending on the computer settings provided by the automaker and driving style of the car owner. The brake band is also considered to be a spare part in this gear shifting unit. On powerful and heavy vehicles, the brake band may distort the drum. This part is commonly replaced during major repairs, when the car comes to the repair service after travelling 200 thousand kilometers or gets for repair with burnt fluid, burnt frictions and steel discs. The unpredictability of vulnerabilities of this transmission is attributed to the point that this smart system was adjusted for many various cars. The wear-out of channels of the valve body and solenoids takes place in distinct areas for different models resulting in the oil pressure loss in various areas of the gearbox. The abovementioned issue results in rapid wear-out of frictions. In Nissan Pathfinder, Infinity etc, the valve body failure is specified by the following caption "Check Engine". It is one of three typical problems with the valve body and sensors. The other two problems are breakdown of solenoids and wear-out of valve body channels. It is advisable to change fluid in this transmission more frequently, not waiting before it becomes opaque. When performing the fluid change on a timely basis, the valve body may operate properly even after 200 thousand kilometers and the overhaul may be delayed until 300 thousand kilometers. The valve body rebuilding is performed in rare cases. More frequently, this component is cleaned or changed by the new one. Issues of the valve body may be divided into mechanical (wear-out) and electrical – breakdown of sensors, wiring, solenoids, circuit boards of the valve body.

Transmission general data The 6-speed transmission Aisin А860Е was designed in 2005 for trucks Hino Dutro (Toyota Dyna) 300 and hit the Japanese market in 2006. However, the mass production of this “invincible” unit was started in 2009. This transmission transmits the torque up to 420 Nm from diesel engine with the capacity 4 liters. This transmission is the main competitor of the Allison 3000 transmission. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type6ATRWD42012Toyota T-IV Technical issues and repair guidelines This transmission is very reliable as all RWD Aisin transmissions. The repair of this transmission in most cases includes oil and filter replacement.The transmission reassembly requires the repair kit of gaskets and seals with valve body spare parts, which are ordered because of sealing rings, which wear out earlier than all other spare parts and gaskets. The electrical part of this transmission is maximally unified: the valve body has 3 simple and invincible On-Off solenoids, 3 interchangeable linear solenoids ( А, C, D solenoids according to the manual), responsible for an ideal gear shifting and a linear solenoid (B). Solenoids usually are quite reliable, but in case of any issues related to the valve body, solenoids are considered the main cause of these problems. Aisin valve bodies produced after 2009 are notable for enhanced durability and are almost not ordered for replacement.

Transmission general data The 4-speed automatic transmission А540E produced by Aisin Warner has been used since 1989 on AWD and FWD 2- 3 liter Toyota Camry, RAV4, Sienna and Lexus ES250 and ES300. In terms of design, this transmission is the part of А140 - А240 series with interchangeable parts, but it can transmit a higher torque. There are several sub-modifications of this transmission. The most significant design changes were introduced in 1994 for А541E used with 3-liter engines, this gearbox differs in friction components of the 2-brake package andadditional 4-th solenoid of the torque converter lockup in the valve body. Tested design, simple electrical components and most importantly control settings that made it impossible to load components of this transmission to maximum torques – all these conditions ensured high reliability parameters of the A541 unit and durability of this transmission. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type4ATFWD/4WD28083Toyota Type T-IV Technical issues and repair guidelines There is no much information on the repair of this transmission, because it operates for a long time without any problems, therefore it is hard to point out any soft spots in А540-541 transmission units. It has been reported that the first released gearboxes (A540H before 1991) had some issues with the reverse gear. The most common reason for appearance of these transmissions in repair services is related to the change of oil and replacement of filter (for А541Е Camry V6). The А540E unit usually gets in repair service with worn-out torque converter frictions causing clogging of the valve body and solenoids, resulting in the pressure shortage in packages (frictions and discs get burnt) and short supply of the pump lubrication (bushing and seal burn and leak).Problems of А540E (А541E, 540H) are commonly related to ill-timed preventive measures for the torque converter, and have nothing to do with durability of this robust transmission capable of covering one million kilometers (standard for Toyota) with just few replacements of the torque converter lockup and ATF change. Usually at the early stages of wear-out of old Toyota cars owners restrict repair actions to the low-cost repair-cleaning of the valve body with replacement of seals and the pump bushing.The repair process obviously includes the pan gasket replacement. When taking more serious approach to the overhaul of used transmission, it is common to replace all gaskets and seals kit. After the overhaul, this transmission can operate until the end of the car service life.

Transmission general data Automatic transmissions A440 and A442 are very reliable units. Repair services for these transmissions resemble the repair of manual transmissions.These 4-speed automatic transmissions were installed on "invincible" and powerful Land Cruiser with the engine 4 liters since 1985 up till 1995 (440F), and then from 1993 the A442F modification made this transmission family of Aisin Warner very popular as well as А340 (AW30-40LE).In 1998 electrical components and the valve body of the A442F. It is a low-maintenance transmission in regard to ATF status, but the fluid cleanness should be taken into consideration.

After 10-12 years of service all gaskets, seals and rings get worn and fragile, therefore they should be replaced. The replacement of spare parts of the repair kit gives this transmission additional 3-5 years of service life. The Precision overhaul kit is used more often than Transtec overhaul kit.The first spare parts that get worn-out are teflon rings and frictions of Forward and Direct packages. The pump cover bushing is a common component to be replaced in these “invincible” transmissions. This problem may be caused by the worn-out torque converter, overheating, clogged valve body or ageing of the transmission itself.The planetary gear Forward is the first to get out of order in old Land Cruisers. It’s a rare case when in this gearbox you get burnt drums, pump gears, valve body, torque converter, but when it happens the structure of this transmission is not to blame, except for the fact that it is allowed to heat the oil with slipping up to 150 С. It is said that after the overhaul this simple and resourceful transmission starts a new service life. This family of transmissions has a long service resource, that allows us to call this transmission “invincible” under conditions of sufficient cooling and timely fluid change.

Transmission general data The family of 6-speed automatic transmissions Ford 6F50 / 6F55 was designed jointly with GM for FWD and AWD vehicles Ford with engines capacity up to 3.5 liters. This transmission is used for powerful Explorer and Taurus with gasoline engines (3.5 liters) and diesel engines (2.5 liters) and intended for a maximum torque equal to 380 Nm. In two years more advanced modification 6F55 was released for the torque equal to 407 Nm and engine V6 (3.5 liters). The list of cars with transmissions of this family is constantly growing. Over the last years these transmissions found application on Mazda Tribute and CX-9, Mercury Mariner, Milan etc. 6F50 is also classified as 6T70 by GM. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type6ATFWD/AWD3809,55Mercon LV Technical issues and repair guidelines The 6T70 unit is considered to be more problematic in comparison with Ford modification. 6T70 had many problems related to electrics and transmission components. In 2012 several significant updates were introduced with addition of wavelike rings in packs and performance optimization of solenoids plate and the valve body. The 6F50 / 6F55 (GM 6T70 / 6T75) transmissions found application on rare American vehicles. For rare overhauls specialists usually order the filter with the pan gasket, which should be replaced with ATF after 50-80 thousand kilometers.It should be taken into account that for this class of automatic transmissions it is crucial to monitor the ATF state (DEXRON-VI - GM or Mercon 5 - Ford) and its temperature. The quantity of fluid required for full change is approx. equal to 9.5 liters. It is advisable to repair the torque converter and clean the valve body when having problems with shifting and operation of the valve body with solenoids. A quick failure of the torque converter caused by contaminated fluid may be considered as a soft spot of this transmission. This problem leads to oil starvation or increased pressure and cranking of bushings. The valve body is repaired by replacement of worn valves with enlarged valves from Sonnax. Problems of this transmission often start with the wear-out of rings and bushings. Contaminated fluid from the torque converter speeds up the wear-out of these seals and damages solenoids.This transmission rarely gets in repair services as well as cars with this good automatic transmission produced by Ford.

Transmission general data The 6-speed automatic transmission 6F35 (6F30) is a collaborative investment project of Ford with GM released in 2002. With regard to transmission components 6F35 is practically a complete analog of the GM 6T40- 6T45 transmission, details for manufacturing of these transmissions are unified to the fullest extent and differ only in electrical elements, filters, and pans. This transmission has been installed since 2008 on popular American FWD and AWD vehicles of Ford (Kuga, Focus, Escape, Fusion...) and Mazda (Tribute) with the engine from 1.6 up to 3 liters. There are two different modifications of the 6F35 – with engines less than 2.5 liters and 3 liters engine. The design of the 6F35 is based on the flagship model 6F50 /6F55= 6T70 /6T75, constructed on modular principle of maximum standardization and interchangeability of blocks.

This transmission is very sensitive to the ATF level. It has no ATF level gauge and its levellevel is tested in compliance with the overflow stopper. As all 6-speed transmissions, the 6F35 (6F30) is sensitive to loads when the ATF is cold. Many complaints have surfaced about erratic gear shifting, with gears harsh engagement and sometimes even slipping out of reverse or forward gear. The problem is most pronounced when the car is on the road, and happens when the transmission is stuck in one gear. It has been found that moving components within the transmission can create more friction, leading to issues requiring repair. The 6F35 Transmission in Ford Fusion and Ford Perform cars is particularly prone to overheating issues. It is important to ensure that the control unit settings are adjusted appropriately, and also that the driver’s driving style is suitable for the vehicle. A dogged cooling system with less than optimal capacity has been found to depend on overall performance, so it may be worth removing Automatic Transmission Fluid (ATF) from the car. This is one of the most common problems with 6F35 conventional 5-speeds transmission issues, and can be easily rectified by a keen driver. The 6F35 transmission offers better fuel economy than its conventional 5-speeds counterparts and covers their 6f35 cars in Ford, covering over 50,000 miles in some cases. It is also good for long run drivers as it provides a greater gear span and optimal speed load combinations with much better optimal combinations. The 6F35 Transmission has a number of design flaws which can cause problems for drivers. One of the most common issues is that the transmission tends to drag engine rpm when shifting gears, especially when towing heavy loads. Another started problem is reluctance or little reluctance when starting off from a complete stop, especially on mountain roads or when driving in stop and go traffic on a Saturday afternoon. Towing is usually the most common cause of transmission problems as it runs the engine harder than normal and can cause significant wear on components over time. The 6F35 Transmission has been known to be reliable but certain design flaws can cause problems if not addressed properly. One common issue is that the computer commanded 1st gear and 5th gear command will switch when read drive is commanded by the computer. This can be easily fixed by changing the range switch to read range switch and ensuring that the input speed sensor is operating properly. Another issue is when the shifter is moved, the rpm figure drops about 200 rpm from its original figure of around 2. This happens for a short time and can cause a few issues if it happens multiple times. One of the most common 6F35 transmission problems is a failed one way clutch. This clutch can cause the wheel speed signal to be lost which will limit engine power and prevent the vehicle from moving. If this happens, it may be necessary to replace the converter. Additionally, if equipped with a problem vehicle, there may also be an issue with floor shift selector lever and display shifts. In some cases, it can even cause a push button start to not work correctly or no throttle response when starting the vehicle. 6F35 Transmission Problems And Possible Solutions can include malfunction valves, control valve, and the valve body separator plate. The malfunction can cause a compromise cooling in the heat exchanger. As a solution on transmissions, it is important to install a fluid heater in order to properly lubricate the transmission. Additionally, removing check ball is necessary to allow for proper flow of transmission fluid. It is also recommended to install a fluid cooler before any additional modifications are done. When using Mercon LV transmission fluid, it is important to note that the deleted hole must be drilled back into the valve body separator plate in order for it to pass proper flow of coolant from one side of the transmission dipstick tube over to the other side. This external cooler bypass valve is necessary for the proper flow of coolant in order to prevent overheating and eventual transmission failure. If an experienced fluid leak is present, it can lead to a deteriorating fluid which compromises lubrication, leading to deterioration of internal components and eventually catastrophic failure of the transmission. Ford Fusion cars that are experiencing 6F35 transmission issues may be left with a failing left half shaft seal or other related issues if not addressed properly. If you are having transmission problems, post your car in our cars section to see if others are having the same issues. Certain problems may be resolved with a simple transmission fluid flush or replacing the left half shaft seal. On our 2015 Ford Explorer, we had to completely rebuild the transmission and it was a costly endeavor. To keep track of any potential issues with your car, it is best to keep a log of when you drive your car and the mileage each time. This can help you detect any problems with your 6F35 transmission early on. I recently had to repair my 6F35 transmission, and Ford sent me a rebuild kit to fix the inherent 6f35 problems. I took my car to the repair shop and they were able to use the kit from Ford to fix the problem. If you are not comfortable with fixing the issue yourself, I would advise you to take your vehicle into a dealership for them to look at it. They may be able to provide you with a powertrain warranty for any potential issues that may arise in the future. If this does not work, then Ford may even send your mechanic out a kit so they can use it in order to fix it up for you. However, this does not always guarantee that the problem will be fixed as some of their kits use faulty factory parts which could just postpone any inherent 6f35 problems until later down the line when they appear again. In order to make sure that this doesn’t happen, it is a good idea to bring the car to a repair shop and have an experienced technician install the unit. The technician will also be able to use engine and transmission data as well as perform line pressure checks, hook pressure transducers, and hook cases to the mainline pressure port.

Many details and spare parts are common with the 5-45RFE. - The complete kit of friction components is ordered for the automatic transmission reassembly. The valve body and the block of solenoids are the main vulnerabilities for the 5-45RFE transmission. After 100 thousand kilometers, it is required to monitor the state of these components (oil pressure, cleaning). The valve body and solenoids often reach the end of their service lifespan after 3-5 years of active exploitation, especially with the worn torque converter clutch. There are problems with the 68RFE torque converter (overrunning clutch, friction, gaskets). It is recommended to replace spare parts in the torque converter quite early, because of problems related to American torque converters.

It had been installed on RWD BMW of 3-rd,5-th and 7-th series with 2-3 liter engines since 1991 up to 1999. The ZF5HP18 unit is a predecessor of famous ZF 5HP19 for a bit less powerful engines (310 Nm in comparison with 325 Nm in 5HP19). This well-designed gear shifting solution with high reserve on transmission components, which served as a prototype of the ZF 5HP19 solution.

This transmission will fully serve the service life, if you monitor the ATF quality and timely replace the metal-plastic filter with a felt membrane. This transmission can operate with different types of oil (works well with oils like Dexron III).Too rapid ATF contamination is a signal of gaskets wear-out and trigged by it risk of oil starvation on fiction components. To perform a typical overhaul with reassembly of worn-out gaskets and rings repair specialists usually order the Overhaul kit for this transmission.The most vivid soft spot of the 5HP18 unit is the clutch package F – the first one to get out of order because of ATF shortage and burnt frictions.The cause of this problem is related to design of the drum F bushing with a sealing, which become the source of leakages leading to oil starvation and bushing cranking.If the abovementioned problem stays neglected, then the clutch drum F with a piston gets burnt together with frictions. This problem is solved by the bushing replacement with the bearing. The oil pump is one more typical part to be worn-out in “old” transmission hard parts under the condition of long-term exploitation with worn-out torque converter and pump bushing.The valve body is a long-running and maintainable unit. The pressure solenoid (EPC) is a main part to be replaced or repaired among electrical components.Shifting solenoids are similar to solenoids used in the 4HP18 unit and they serve for a long period of time. EPC solenoids are the first to get out of order, then comes the turn of the TCC solenoid. In all other respects, the resource of this transmission is compatible with the resource of the whole car.

Transmission general data The 5-speed RWD transmission 5EAT was designed in 2003 by Jatco on commission from Subaru for popular models Tribeca, Impreza, Outback, Legacy on a constructive basis of Jatco JR507E , reengineered for the engine room of Subaru. Since 2005, the 5EAT unit has been operating on LEGACY model equipped with engines having the capacity from 2 to 3.6 liters. Later this transmission was paired with 3-liter engines Н6 on American models of Tribeca and Outback. The Impreza model for the Japanese market was also equipped with this transmission.

Consequently solenoids wear out and the valve body gets clogged.Therefore, manufacturers of automatic transmissions assume that it is better to change the fluid with filter after covering 80 thousand kilometers (depending on the driving style) and change it the next time when oil transparency is not good enough. After 120-150 thousand kilometers, it is necessary to check for the presence of metal grit in the pan. Oil change and first overhauls usually require order of the plastic filter with felt "accordion" connection.Specialists install the external main filter sequentially to metal coarse mesh filter. The filter is located outside of the transmission and access to it is maximally facilitated. The main filter helps to keep the oil clean and reduces the wear of the friction components and aging of solenoids. These measures are recommended for all old transmissions, which have a regular filter with a metal mesh.The repair kit of gaskets and seals/Overhaul kit is usually ordered with the kit of friction components. There are two types of solenoids which are usually get replaced: solenoid in the Direct package (this solenoid operates more intensively than others) and solenoid of the second type with a cover plate, and the problem is specified by the computer error (The problem may lie in the spooling burn-out resulting in improper gear shifting or wear-out of the valve mechanical part.). The list of typical problems in the 5ЕАТ unit also includes solenoids and the speed sensor overheating and clogging with dirt and metal chips from the torque converter. The list of soft spots for this transmission also include: -Pump with bushing and seal. - Shaft with a sun gear of an interaxle planetary gear for vehicles with engine capacity over 3-liters. The design of the 5ЕАТ unit is similar to the construction of Jatco’s RE5R05. Many spare parts in these transmission units are interchangeable. But the valve body and solenoids are different.
