This transmission model is not electronically controlled. It is instead controlled by throttle position and also by a governor. This transmission is electronically controlled by an electronic shift control module. Mechanically similar to the A43D. Four speed automatic with lockup torque converter, electronic controls and viscous coupling center differential. Three speed automatic front wheel drive , longitudinally mounted. Even with FWD, the engine is also mounted longitudinally.
These transmissions have a governor gear. Unlike the AE counterpart which is electronically controlled, the AL 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.
This is the twin turbo only heavy duty version with some internal mods. The main case is similar to the common AE 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 significantly higher than the standard AE used with the 2JZ-GE normally aspirated engine [ citation needed ].
Type: Full automatic 4-speed transmission with converter lock-up. Mechanical throttle control input for kick-down function. Connects to external oil cooler. This particular version has a weak reverse — prone to noise and failure — failure included problems with 1st brake. I6 and V8 versions similar. However V8 versions have slight internal upgrades to handle the increased torque LS?
Smaller parts, a hydraulic circuit with fewer components allow the transmission to maintain the same size as the previous LS 's unit. Aluminum has also replaced steel on gear tooth surfaces. The torque converter can lockup from 2nd to 6th gears. Final drive ratio is 2. Same gear ratios as the AA80E but a shorter 3.
