Moreover, this solution may be used on Ad Van. This CVT was developed as a budgetary and reliable option for "long-running" cars. The main competitor of this CVT is AW60-40 by Aisin.The design of JF414E components is maximally simplified according to the principle "nothing in excess" Repair procedures and typical problems Rebuilding procedures of this transmission are related to the replacement of spare parts (namely, gaskets, seals and friction elements).Usually repair specialists have to replace worn-out friction elements. Bearings also may be replaced in the course of the overhaul. The most common bearing to be replaced is a double-row center bearing. This bearing is damaged by overloads and driving with vibrations at high speeds.The valve body of the JF414 unit is quite reliable and rarely gets replaced. The main spare parts of the valve body are gaskets and solenoids. The transmission exploitation with contaminated fluid, worn-out torque converter clutch, and especially overheating may shorten the service life of solenoids and valve body gaskets by several times. The list of vulnerabilities of Jatco valve bodies includes sensors and a circuit board located in the valve body. Also these valve bodies are very sensitive to contaminated and hot fluid with metal chips.Computer settings are well-adjusted for packages and the torque converter lockup, which turns on at the very end of the 3-rd and 4-th gear, allowing the friction to have quite a long service life.

Transmission general data The 9-speed automatic transmission 9G-Tronic (725.0) was developed by the company Mercedes-Benz and was released in 2013, replacing the model 7G-Tronic. When developing this gearbox, Mercedes-Benz’s transmission specialists concentrated on simplifying the structure of the transmission, while maintaining its size and implementing the solution with 9 gears, minimum number of planetary gear sets and mechanisms of gear shifting. As a result of intensive computer system analysis and synthesis, transmission engineers solved this problem by means of only 4 planetary gear sets and 6 gear shifting mechanisms. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type9ATRWD/AWD100010,26236.16 Since 2014, the 9G-Tronic transmission has been installed on cars of E-(including coupe/cabriolet) and CLS Classes, since 2015 – on GLC, GLE (including coupe), and GLS Classes. The 9G-Tronic is considered to be the world’s first 9-speed automatic gearbox in the segment of premium cars. The performance efficiency of this amounts to incredible 92% (this parameter of 7G-Tronic was equal to 85%). The span of gear ratios is equal to 9.15. Despite two additional gears and the maximum torque up to 1000 Nm, 9G-Tronic requires the same amount of space for positioning as its predecessor. Three speed sensors monitor the operation of the gearbox and provide the TCU with relevant information for efficient gear shifting. Three different modes of operation allow the driver to pre-select an appropriate algorithm of gear shifting. It improves driving comfort and reduces the noise level. The 9G-Tronic transmission has 3 driving modes: «Comfort» («C») — for driving with low fuel consumption; «Sport» («S») — for fast driving style at high engine RPM; «Manual» («M») — for fast driving and manual gear shifting via the system DIRECT SELECT. According to representatives of Mercedes-Benz, this transmission is suitable for cars with rear and all-wheel drive, as well as for hybrids and E-motors.

Transmission general data In the fall of 2010, engineers of Mercedes-Benz presented an updated version of the automatic gearbox 7G-Tronic Plus. For the first time this gearbox was applied in the CL-class (216 series). According to representatives of the company, this gearbox became more comfortable, quick-operating and economical than its predecessor. The 724.2 gearbox is equipped with the torque converter of a new generation. This torque converter is more durable; it has reduced noise level and faster response time thanks to innovative technology. In addition, this gearbox is equipped with the “start-stop” system. The engine RPM gets reduced in the ECO mode that significantly contributes to fuel economy. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type7Hybrid SystemRWD9,5236.15 The 724.2 gearbox undergone systematic optimizations to reduce energy losses caused by traction. This and other measures made it possible achieve 7% fuel economy. In 2012 a new car Mercedes-Benz SL was equipped with the 7G-Tronic Plus. The roadster became the first car of Mercedes-Benz, which was equipped with a newly developed Direct Select paddle shifter on the centre console. This feature is used for more dynamic driving style. The latest changes in 7G-Tronic Plus were introduced in 2013. The updated version of this gearbox was used in E300 BlueTEC HYBRID, where the 20 kW e-motor was integrated in the case of the torque converter. In 2013 the 7G-Tronic was replaced by the 9G-Tronic automatic gearbox. Peculiarities: - 7-forward gears: increased difference between gear ratios of lowest and highest gears, while maintaining small intervals between gear ratios in other gears, increases driving comfort. - Optimal engine RPM contributed to low fuel consumption and smooth gear shifting. - Solid power reserve: fast accelerations became possible thanks to reverse gear shifting with omitting of several gears; - New generation torque converter: reduced wear, lower noise level and better responsiveness thanks to innovative technology. - Reduced fuel consumption: the function “Start-Stop ECO” ensures that the engine switches off temporarily when the car gets stick in traffic jams of stops at traffic lights. - Comfort and sportiness: drivers can choose from 3 operation modes: «E» (Economy) – to reduce fuel consumption, «S» (Sport) – for sporty driving style, «М» (Manual) – for rapid gear shifting with the help of paddle shifters.

Transmission general data The 6-speed DSG gearbox DQ250 - 02E (S-tronic) with a dual wet clutch was firstly used in 2003 in cars with engine capacity from 1.6 up to 3.2 l. VW started to install this gearbox serially on a number of vehicles (GOLF, JETTA, PASSAT etc). Expensive models of Seat and Scoda also were equipped with this gearbox. This gearbox is capable of transmitting quite high torque (up to 350 Nm). The structural design of this robotic transmission was created by VAG specialists jointly with the company "BorgWarner". Later this project was joined by the company "Luk". Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type6DSGFWD/AWD3506,95,5G052182 Technical issues and repair guidelines Generally, these gearboxes serve quite reliably for 2-5 years. The warranty of the automaker has been extended (only VW) up to five years. At this period the percentage of visitors to service centers is still quite high. Customers complain about the issues related to vibrations, kicks, jerking caused by the double-disk clutch, velocity sensors, chips in the gearbox that damage mechatronics. First repairs of these sophisticated and highly-priced gearboxes are related to replacement of filters: external filters of heat exchanger and ATF, which should be changed with the external filter. Minor and repeated repair operations of DQ250 involve replacement of VFS solenoids, which get damaged by dirt from ATF and, as a result, lose their operating qualities related to changing the oil flow and its pressure. As a result, VFS solenoids become "rejected" by the control system. The reassembly of 02E -DQ250 gearbox with the replacement of rings, seals and filters is “a must” procedure to prolong the lifespan of its friction elements and solenoids.

Transmission general data This dual-clutch transmission is controlled with the use of electric motors instead of hydraulic valves of piston valves and the pump.This transmission uses the main tested advantage of mechanical gearboxes – the clutch is relocated to open space and wear products of clutches are immediately get out from the transmission without causing any harm. Neither planetary gears nor hydraulic switch control are used for this purpose. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type7DSGFWD2501,71,7G052512 Technical issues and repair guidelines Gear shifting is implemented by two fork connectors controlled from a closed small hydraulic Mechatronic which may contain approx. 1 liter of ATF. This immediately reduced the cost of production at the expense of the transmission resource. Such transmissions cover 200 thousand kilometers with some problems. But at the same time advantages of this transmission are very attractive (high level of efficiency (up to 97%) and dynamics). Repair and typical problems of DQ200 These transmissions are quite complex for repair, therefore replacement is more preferable option. The most common problems are related to all new elements: - The dual-clutch gets worn out early or unevenly in case of an aggressive driving style. - The new electric oil pump breaks too early and frequently and operates in an abnormal fashion. - Typical issues with operation of sensors. - High oil pressure in Mechatronics units push out the oil with fatal consequences for the trasmission. As a result, automakers had to modify the transmission and some separate units each 2-3 years, investing more and more financial resources in making the transmission more sophisticated and expensive and hope that the project DSG will pay off before releasing of 1 million transmissions. The most common problem that occurs in these transmissions (except clutches vibrations): damage of the shifting fork Reverse\6 (including bearing parts). There are also different defects successfully fixed in services specialized in repairing DSG with a dry clutch. The repair process related to components of this transmission is quite complicated and therefore this option doesn’t have much support among car owners, especially when the engine resource comes to an end.

Transmission general data The constantly variable transmission (CVT) ZF CFT23 of the German manufacturer of auomatic transmissions with the trade name "Ecotronic" has been installed on Ford Focus, C-MAX with engines 1.6 - 1.8 liters since 2003 until 2008. Later more powerful CFT30 was developed for Ford vehicles with a 3-liter engine. This CVT had been installed before 2008 on powerful Taurus as well as on Ford Focus of European assembly. This CVT was also noticed on Mercury Sable. The “push” belt construction is used in СFT23 as in RE0F09A, /JF010E by Nissan instead of “pulling” belt used in 01J CVT (Audi).

Original spare parts for repair of these CVT (produced by ZF) are basically neither produced nor sold. It is almost impossible to get even used spare parts for repair of CFT. Therefore the most popular spare parts for repair of CVT CFT23 are filter and repair kit of gaskets and seals. Experienced specialists in repair services recommend to change the whole kit of rubber gaskets and seals as well as filter and oil without waiting for problems with surfaces of cones after 3-4 years of intensive operation.

Transmission general data The U440E unit was designed by Aisin Co in 1999 for small FWD cars Toyota Yariz, Witz and Corolla with 1.3-liter capacity, which replaced the AW60-40 unit. This gear shifting solution usually can be found on the Japanese market of right-hand drive vehicles. The U340 unit produced simultaneously with U440E was chosen by Toyota for Corolla with the engine capacity of 1.5 liters and higher. The U540E unit more known as AQ4 is a quite rare solution for Daihatsu with more simple complete set. This gearbox is also used for American small cars Cadillac, Buick, Ford and Chinese Donfeng, Landwind under names AW80-40LS and AW81-40LS. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type4ATFWD1505,82,1Toyota Type T-IV Technical issues and repair guidelines The repair of this transmission is usually performed for cars with high mileage and already worn-out torque converter lockup unit. Each 4-th case of the rebuilding of this robust unit requires MasterKit – complete kit of spare parts. After the exhaustion of resource of this transmission (and rings wear-out), the first component to be worn is a set of frictions with steel discs in the clutch package Direct. After that, С1 Forward and Overdrive frictions get worn and then others. The "soft spot" of AW81-40 components is considered to be the planetary gear, which even during testing required some servicing before covering 100 thousand kilometers. The reason is related to design issues. The transmission of maximum operating torque via the gear to the differential by means of strong side loads leads to the damage of units in this package. (Only paired with 1.6 liter engines). The major wear-out of friction units and consequent damage of the pump bushing takes place when neglecting the oil pressure parameters and wear-out of the torque converter. As for electrical components, standard cleaning and valve body reassembly, repair specialists order EPC and On-Off solenoids. Sometimes the differential is also ordered for the overhaul. In old cars, specialist often install external fine filter. The filter helps to preserve clean ATF and decreases wear-out of friction components. The spare parts resource will be significantly increased, if ATF is kept clean and the torque converter gets repaired after covering 150- 200 thousand kilometers (depending on the car type and driving style) and preventive cleaning of the valve body and solenoids. More often problems occur in cars with engines capacity equal to 1.3. The torque of these engines turns out to be too high for this automatic unit and electronic control allows the driver to load the transmission to the maximum. Careful usage of cars with this gearbox without fast accelerations from traffic lights and slipping on deep snow allows postponing first overhauls of this “invincible” gearbox for 6 or more years.

Transmission general data The rare 4-speed automatic transmission AW450-43LE had been installed since 1998 until 2007 on the RWD model ISUZU NPR/ NQR. with engines capacity of appr. 5 liters. In terms of design, this transmission is similar to AW442F. In most cases Isuzu models come to repair shops with the purpose of fixing the transmission. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type4ATRWD12,56Type T-IV Technical issues and repair guidelines This transmission for RWD vehicles is very reliable as all Aisin transmissions with high torque capacity. In most cases, problems occur in old vehicles and mainly associated with their age. If the car owner keeps track of the thermostat condition, then the lifespan of the automatic transmission AW450-43LE can exceed the service life of the car itself. The torque converter is the first component to get out of order in this transmission, then it leads problems with the worn-out oil pump and bushings. The repair kit of gaskets and seals is included in the common order for a complete reassembly of this transmission. Rare repair cases usually include replacement of the Direct package. In most cases friction friction components of this package are the first to get burnt because of high loads. Frequently, this transmission comes to the repair shop completely burnt friction elements. In such cases, specialists order a full kit of frictions as well as the kit of steel discs.
