Oil Pump and Stator Support

Oil Pump and starter support








The fluid pump is a crescent gear pump and is driven directly from the crankshaft by means of drivers on the converter impeller hub. The fluid pump is bolted to the transmission housing.
The stator support is part of the fluid pump. Splines on the support locate and hold the converters stator.

Planetary gear sets
The individual gears are shifted by means of two planetary gear sets connected one behind the other.

Clutches and bands
The individual ratios are selected by means of four multiple clutches, a brake band and a roller one-way clutch.
The components are controlled by the PCM through Pulse Width Modulation (PWM) solenoid valves.
