Geartrain

Power is transmitted from the torque converter to the planetary gearsets through the input shaft. Clutches are used to hold and drive certain combinations of gearsets. This results in 6 forward ratios and one reverse ratio which are transmitted to the output shaft and differential. The ratios are as follows:

Gear Ratio:

Single Planetary Gearset
The single planetary gear overdrive carrier is driven by the input shaft. The single planetary gear set consists of the following components:
^ One sun gear
^ Four planetary gears meshing with the sun gear
^ One planetary carrier
^ One ring gear

Ravigenaux Planetary Gearset
The ravigenaux planetary gearset is splined to the output shaft and consists of the following components:
^ Two sun gears of different sizes
^ Three short planetary gear pinions meshing with the sun gears
^ Three long planetary gear pinions meshing with the sun gears
^ One planetary carrier
^ One ring gear

Output Shaft
The output shaft provides torque to the driveshaft and rear axle assembly. It is driven by the ring gear of the planetary gearset.
