D. OIL PUMP
OVERVIEW
The oil pump in HPT 6 A/T (6F33) is the paracoid
type that improves the displacement efficiency, and
it is integrated with the 26 brake chamber.
The oil pressure generated by oil pump is used for
clutch and brake operations.
And, the oil lubricates the transaxle components
and is circulated in torque converter and cooler.
COMPONENTS
E. VALVE BODY
OVERVIEW
The valve body contains two on/off solenoid valves
and six variable Force solenoids.
The on/off solenoid valves are actuated by the TCU
and maintain two positions; open and closed.
These valves are used to switch the shift valves.
The variable force solenoids convert an electric
current into a proportional hydraulic pressure.
They are energized by the TCU and supply variable
pressure to each of the clutch or bands dedicated
regulator valves.
