Toyota A transmission

Toyota Motor Corporation's A family is a family of automatic FWD/RWD/4WD/AWD transmissions built by Aisin-Warner. They share much in common with Volvo's AW7* and Aisin-Warner's 03-71* transmissions, which are found in Suzukis, Mitsubishis, and other Asian vehicles.

The codes are divided into three sections

A140L

[edit]

4 Speed Hydraulic Controlled Automatic Transaxle (2-way overdrive)

Applications (calendar years)

These transmissions have a governor gear. Unlike the A140E counterpart which is electronically controlled, the A140L uses a plastic governor gear to select which gear to go into. Over time and wear, this plastic gear's teeth shred and eventually cease to be able to control gears. This results in a transmission that can only shift to first and reverse, but not to any further forward gears. Replacement of this governor gear is relatively inexpensive compared to a replacement transmission as it can be serviced without taking the transmission out of the car.

The detachable bell housing, which attaches the main transmission case to the engine, has an engine-specific bolt pattern, which appears on its upper surface as cast-in letters. "J" indicates the straight-6 1/2-JZ engine, "U" the V8 UZ engine.

[edit]

OEM with 2JZ-GTE twin turbocharged engines only. This is the twin turbo only heavy duty version with some internal mods. The main case is similar to the common A340E but not interchangeable, the bell housing has "J3" cast into the upper surface, and is larger diameter to accept the larger torque converter and special flex plate. Maximum power using the stock internals should be limited to 500 (significantly higher than the standard A340E used with the 2JZ-GE normally aspirated engine) [citation needed].

  1. ^ Differences in gear ratios have a measurable, direct impact on vehicle dynamics, performance, waste emissions as well as fuel mileage
  2. ^ Logically, the gearset concept (layout) provides for this 2nd reverse gear, but it will most likely not be used in the transmissions that the car manufacturers eventually bring to market. In some data sheets, the gear ratio of R2 is given, presumably a careless error

8-speed automatic transmission

Applications (calendar years)

8-speed automatic AWD transmission. Same gear ratios as the AA80E but a shorter 3.133 final drive ratio is used.

Application(s)

Pairs with Toyota 2GR-FSE and 2GR-FKS V6 engines.
