Toyota A transmission

'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:

The letter A = Aisin-Warner Automatic.
Two or three digits.
*Older transmissions have two digits.
**The first digit represents the generation.
**The last digit represents the particular application.
*Newer transmission have three digits.
**The first digit represents the generation. Note: the sequence is 1,2,...,9,A,B with A and B being treated as digits.
**The second digit represents the number of gears.
**The last digit represents the particular application.
Letters representing particular features:
* D = Separates 3-speed A4x series from 4-speed A4xD series
* E = Electronic control
* F = Four wheel drive
* H = AWD Transverse mount engine
* L = Lock-up torque converter

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.
