Right hand side of a Torqueflite automatic

The Torqueflite MA904A or Baby Torqueflite is a 3 Speed Automatic transmission made by Chrysler and used in the first generation Sigma behind the 2.0 Litre Astron. The transmission is similar to the Torqueflite used in 6 cylinder and V8 Chryslers - with the torque converter reduced in size from 273mm to 241mm.

The transmission consists of two clutches, an over-running clutch, two servos and bands and two planetary gear sets. Kickdown is actuated by a kickdown cable connected to the throttle rod.
