Toyota A transmission

Toyota Motor Corporation's A family is a family of automatic FWD/RWD/4WD 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. A = Aisin Automatic. Second last digit denotes number of gears. Last digit is the Toyota series number -E=Electronic control -F=Four wheel drive -H=AWD Transverse mount engine -L=Lock-up torque converter

2.811.5491.0000.7062.296

A140L

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

Applications:

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.

8 Speed Automatic Transmission

Applications:

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

Variant of the AA80E used for the AWD Lexus LS460. Gear ratios are the same, but a shorter 3.133 final drive ratio is used.

AA81E

Pairs with Toyota 2GR-FSE V6 engine.
