ATSG - FORD SATURN - TAAT - (2006)

Saturn – ATSG (Automatic Transmission Service Group) PDF. This manual will cover tear down and re-assembly of the transaxle along with basic diagnostics for both mechanical and electrical. Special items included in this manual are: powerflow application chart, actuator application chart, line pressure testing specifications and transaxle identification.

The Saturn TransAxle Automatic Transmission (TAAT) first appeared in the 1991 Saturn vehicles. The general design of the Saturn automatic transaxle is a parallel shaft front wheel drive transmission which also contains the final drive. The transaxle provides four speeds forward and one reverse using four multiple disc clutches, a four element torque converter with a lock up clutch, 1st gear sprag clutch, and a servo actuated dog clutch. The most significant departure from the traditional automatic transaxle comes from the use of electronic controls. This unit utilizes five electro-hydraulic actuators in conjunction with a powertrain control module (PCM) and it’s sensors to control shift timing, shift feel, and provide on-board diagnostics.
