The 6-speed 6DCT150 was developed by the
company Dongfeng Getrag. It is considered to be the most space-saving dual-clutch
gearbox worldwide. "Cascading Gears", implemented in this
transmission, helped to reduce the total weight of the gearbox. Another feature
called "Smart-Actuation” contributed to significant reduction of energy
consumption. This transmission operates with engines, which have low torque. It
is intended for compact and medium cars.

TOYOTA ECVT P110 / P111 / P112 / P210 / P310 / P311 / P312 / P314 / P410 / P510
CVT-type automatic transmissions are produced by Aisin for hybrid cars Toyota and Lexus. These transmissions have an initial prefix “P” (it means that these transmissions belong to the planetary type). Some people mistakenly believe that the planetary gearbox cannot be a CVT, but it’s wrong. Planetary gearboxes (not all) have a metal chain (analog of a belt in CVT). Even Toyota considers these planetary gearboxes as CVTs and name them as eCVTs. Undoubtedly, the planetary gearbox differs from standard CVTs (on the global scale the planetary gearbox is not so complicated as CVT), but it is still CVT with its problems and repair peculiarities.

The first CVT of the planetary type eCVT (model P110) was manufactured in 1997 and was installed on the first generation of Toyota Prius for the domestic Japanese market. In 2000, this CVT was upgraded for Prius and was named as P111. Toyota Prius equipped with the P111 transmission was sold not only in Japan, but also in the US.
The new planetary CVT P112 was designed in 2001. This gearbox was intended for more powerful (2,4 liter engines) and heavyweight cars (Toyota Estima Hybrid and Toyota Alphard Hybrid). The planetary CVT transmission P112 found application in Toyota Prius, which was sold in Europe, Canada, and USA. The P112 actually became one of the most popular CVTs of planetary type.
The planetary CVT P310/Q211 (named as Q211 for Lexus) was manufactured in 2005. This transmission was specially developed for SUVs with FWD and 3.3-3.5 liter engines. This transmission was installed on hybrid cars Lexus RX400H, Toyota Kluger Hybrid.
The planetary CVT P311 was released in February 2006. It was intended for FWD cars with 2.4 liter engines. In comparison with P112, this gearbox is noted for reduced fuel consumption when the engine
has high RPM rates. In the same year, Aisin started production of the transmission P312 which was designed on the basis of P311. This transmission was supplied to Nissan Motor Company Co., Ltd (for application in Nissan Altima Hybrid in the US market. It was also installed on Toyota Harrier Hybrid 3,3 for the domestic market of Japan.
The eCVT P410 was launched in production in 2009. This transmission was developed for FWD cars equipped with 1.8 liter engines. Peculiarities of this transmission include transfer gear case assembly and possibility of smooth reduction of the engine speed at high RPM rates. This eCVT as well as P112 found application at a global scale, because it was installed on Toyota Prius, which had been sold from 2009 to 2015 all over the world. In addition, the P410 transmission was used for a new range of cars ( Toyota Prius Alpha, Toyota Prius V, and Lexus CT200H.
In July 2009, Aisin released a new modification of eCVT named as P311-03A. This transmission had an upgraded oil pump and engine cooling system. In 2010, Aisin started production of the P410 planetary CVT for plug-in hybrid vehicles.
In August 2011, Aisin started production of a new planetary CVT named P314 for 2,5 liter engines (for FWD and AWD). This transmission was equipped with a new oil pump, which ensured lower fuel consumption. According to Toyota plans, this transmission also should find a global scale application, because cars equipped with this transmission are sold all over the world (Toyota Camry Hybrid (for markets of the US and Japan), Lexus NX300H (for European market), and Toyota Rav4 Hybrid (for all global markets). The P314 eCVT is considered to be quite “new” and it is rarely found in repair services.
In November 2011, Aisin released a new eCVT transmission named as P510. This gearbox has a new design and operates with an NZ-series engines (engine capacity = 1.5 liters). The list of cars which use this transmission includes Toyota Corolla Hybrid, Toyota Yaris Hybrid, Toyota Prius C. The P510 transmission in noted for its light weight, small dimensions, and increased efficiency.
In January 2016, Aisin released a new eCVT P610. This gearbox was intended for application in a new generation of Toyota Prius.
Problems and repair procedures
Abrasive particles often damage oil pump of eCVT , in case of ill-timed ATF change.
1) The planetary gear set wear is often caused by abundance of metal shavings. It is especially common for planetary type CVTs P112 installed on Toyota Prius (produced in the 2003-2008 timeframe).
2) Repair services for eCVTs often include replacement of gaskets and seals (Overhaul kits), pump seal, axle shaft oil seal.

TOYOTA K110 / K111 / K111F / K112 / K112F / K114
The first generation of CVT transmissions designed by the Japanese company Aisin was produced in August of 2000. Initially, the CVT K110 was designed for FWD cars with the engine capacity of 2 liters. According to many sources, Toyota (co-founder and co-owner of Aisin) combined the license (bought from Jatco) and its own developments in the field of CVTs (the first CVT named as P110 was successfully tested by Toyota on Toyota Prius with the body NHW10 for the domestic Japanese market).
Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type∞CVTFWD85Aisin CVTF7004, Toyota 08886-02105
Technical issues and repair guidelines
The first
car with the K110 CVT was Toyota Opa, 2.0 (2000-2005), which was sold
exclusively in the domestic market of Japan. A year later (in 2011) the K110
transmission was installed on sedans Toyota Alion/Toyota Premio and minivans
Toyota Voxy/Toyota Noah/Toyota Estima, etc. All these right-hand drive cars
were originally intended for sale at the domestic market of Japan as well as in
some Asian countries. For 4 years of production, Toyota managed to fix some
standard issues related to this CVT. In 2004, Toyota released an improved
version of K110 which was named as K111/K111F (prefix “F” means that this CVT
is intended for all-wheel drive vehicles).
The K111
transmission was designed on the basis of K110, and these two transmissions are
very similar in terms of technical solutions. The K111 transmission (in
contrast with K110) has a new belt as well as linear control over the N gear
and acceleration. It has a positive impact on fuel efficiency and transmission
performance characteristics.
For some
time, Toyota was actually “catching up” with other Japanese companies in terms
of CVT application. Therefore, Aisin (which produced CVTs for Toyota) had to
use spare parts of different manufacturers for assembly of K110 and K111.
Moreover, Aisin heavily depended on third-party suppliers and on quality of
supplied spare parts. For example, belts for Aisin CVTs were produced by the
German company Bosch. Toyota didn’t want to put up with such state of affairs.
The Japanese auto giant wanted (via its subsidiary Aisin) not only to fully
control the whole process of transmission production, but also to develop and
introduce new CVT technologies. Thus, in 2002, Aisin jointly with Bosch
established a joint company Shivutech Co., Ltd. (trade mark CVTEC). The purpose
of this company was the development and production of components for CVTs.
Three years later in 2005, CVTEC developed the belt for a new type of CVT.
According
to the original technology, this new push belt consists of thin steel sheets
with high-precision gaps (equal to several microns). This solution ensures high
strength of belt elements. In addition, the durability of this belt was
enhanced by the sandblasting procedure. These measures made it possible to
launch in production a new series of CVTs K112/K112F in October of 2005. These
CVTs with higher torque transmission capacity were initially intended for
coupling with 2,4-liter engines. The first car equipped with the K112/K112F
transmission was Toyota Rav4. Later this CVT was applied in Toyota Estima,
Toyota Blade, Toyota Vellfire and many other cars.
Typical
problems in K110/K111/K112
Transmission
specialists often have to deal damage of bearings on the input shaft of K111
and K112. This problem may be caused by production defects or contaminated ATF
with metal shavings. These metal shavings reach the bearing via a small hole in
the gearwheel. As a result, balls in the bearing become cemented leading to its
wear. Over time, the “dying” bearing damages the gear-wheel itself
If K110 /
K111 / K112 transmissions get overheated (ATF has a “burning” smell), then it
may lead to replacement of the complete set of friction clutches. In this case,
transmission specialists also replace gaskets,
rings, and seals (the reason is simple – rubber hardens affected by temperature
and becomes less flexible; eventually, it leads to oil leakages. Long-term
usage of the car with worn friction clutches and rings leads to overheating of
pistons and their consequent replacement.
Acceleration
from rest with the cold CVT (in winter time) leads to curving of the CVT belt
on cones (on minimum radius). At the same time, the belt touches cones on the
minimum area. It often leads to the belt slippage (with cold ATF). In this
case, the belt wears down and scratches cones. With time surfaces of cones will
have tears. The belt slippage also will have a negative impact on
solenoid-operated valves.

Technical issues and repair guidelines
Besides Lada Granta, this CVT transmission was also installed on Nissan Almera and March models with up to 1.6 liters. 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.

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.

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.

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.

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".

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).

Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type7DCTFWD/AWD5507,56,7G 052 529 A2
Technical issues and repair guidelines
VAG DL501 (0B5) gearbox is structurally divided into two compartments - "mechanical" where the hypoid oil is used for mechanical gearboxes, and an "automatic" part with double clutch frictions and the valve body, where "intelligent" oil is used specially for DL501 - G 052 529 A2.
Typical problems
Chips from the drum harm both the filter and components of the gearbox, and the electrics. All gearboxes including 7-speed DL501 have issues with Mechatronics.The gearbox operation with metal chips in oil leads to rapid wear-out of solenoids. As far as the hardware of this gearbox is concerned, the main component to be replaced is the whole clutch drum.

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).

Technical issues and repair guidelines
But in more powerful CFT30 the belt did not cope with loads (similar to problems of Nissan Murano), therefore the pulling belt was applied here as in the variator 01J.
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. The belt is produced by only one company and similar to other CVTs with pushing belt. Friction clutches F and steel discs used in this transmission are the same as for ZF 5HP24/30/19.
