six and V8s), including the obscure Chevrolet V8 bellhousing pattern when used with the Pontiac Iron Duke which was the base motor in some 1980-83 AMC and Jeep products (this bellhousing pattern is a rare find since transmission cores are usually sought after by drag racers building a Powerglide or TH200 derivative using THM2004R internals inclusive of a modified torque converter front face and/or torque converter adapter ring allowing the use of the TorqueFlite bolt pattern to a GM flexplate), and a GM 60 Degree V6 bolt pattern when used with the GM 2.8L LR2 of this transmission.

It was equipped with four direct friction plates. This transmission differed from the A904 by having a reinforced case and internals. Narrow ratios are 2.45/1.45/1.00:1 and wide ratios are 2.74/1.55/1.00:1.

It was equipped with five direct friction plates. These automatics had lower first and second gear ratios to allow the lower-powered engines to provide better acceleration without sacrificing highway fuel economy. Frequently used today in drag racing.
