| Description |
| • |
The oil pump is powered by the engine. ATF passes through the oil filter
and gets distributed along the oil channels.
|
| • |
The oil becomes highly pressurized as it exits the oil pump and passes
through the line pressure valve before being fed to the clutch & brake
control valve, clutch, and brakes.
|
| • |
TCM controls the hydraulic pressure using solenoid valves and controls
clutch and brake operations.

Description • The oil pump is built-in as a single unit with the 26 Brake chamber. • Rotation of the pump builds the hydraulic pressure needed for the lubrication of the various parts of the transaxle and operation of the clutch and brakes.
