The hydraulic system consists of a valve body, an oil filter and an
oil pump.

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.
