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.

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].

8-speed automatic transmission

Applications (calendar years):

Gear ratios:

1 2 3 4 5 6 7 8 R
4.596:1 2.724:1 1.864:1 1.464:1 1.231:1 1.000:1 0.824:1 0.685:1 2.176:1

The AA80E (Aisin TL-80SN) becomes the world's first eight-speed automatic transmission. Smaller parts, a hydraulic circuit with fewer components allow the transmission to maintain the same size as the previous LS 430's unit. The aluminum die-cast case is 10% lighter, yet 30% more rigid, even with two additional gears and a 22% greater torque capacity the new transmission weighs 95 kg or 10% more than the previous unit. With new micro-laser technology gear tooth production tolerances have been reduced 50%. Aluminum has also replaced steel on gear tooth surfaces. Shift times are as low as 350 milliseconds or 41% faster than the previous LS 430's six-speed auto.

The IS F and LS 460 (with sport package) use Sport Direct Shift (SPDS) which allows for faster shift times. The torque converter can lockup from 2nd to 6th gears. Final drive ratio is 2.937.

AA80F

edit

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