Hydraulic System
Fluid Pump
The fluid pump provides a supply of transmission fluid under pressure to operate, lubricate, and cool the transaxle. The oil pump is a trochoid gear positive displacement pump with output flow proportional to demand. The oil pump is mounted to the transaxle case.

Main Controls
The main control valve body directs fluid under pressure to the torque converter, band servos and clutches. A system of valves, passages and check balls are used to direct fluid to the necessary component. The solenoid assembly is used to operate various valves in the valve body in order to control transaxle shift timing, feel and schedule.

1-2 Accumulator
The 1-2 accumulator cushions the application of a friction component during a 1-2 upshift. The 1-2 accumulator is located within the upper control valve body.

N-D Accumulator
The N-D accumulator cushions the engagement of the forward clutch when the transaxle is shifted from NEUTRAL(N) to DRIVE(D). The N-D accumulator is located the main control valve body.

D-R Accumulator
The D-R accumulator cushions the engagement of the Reverse Clutch when the transaxle is shifted from DRIVE(D) to REVERSE(R). The D-R accumulator is located in the main control valve body.
