Input Clutch
The input clutch assembly is located directly behind the oil pump housing, and rides on the reaction shaft support journal. The assembly consists of the following:
- Input shaft
- Input hub
- Clutch retainer
- Clutch pistons Overdrive hub Underdrive hub Three input clutches (underdrive clutch, overdrive clutch and reverse clutch).
When the torque converter turbine turns, the input shaft, hub and clutch retainer also turn
Each of the three clutches in the input clutch assembly supply input power to a particular component in the planetary gear train when they are hydraulically applied. They are connected to the planetary gear-train through the overdrive hub assembly, underdrive hub assembly and the front sun gear assembly. When any of these clutches are applied, they turn or drive a component which is an input to the planetary gear-train.
