Hydraulic System

Filter
Fluid in the sump area formed by the transaxle pan flows through a filter to the pump assembly. A magnet attached to the transaxle pan collects unwanted metallic material.

A thermostatic fluid control valve prevents foaming of fluid by maintaining a sump level below the rotating components.





Fluid Sump and Case Components

The thermostatic fluid control valve stores fluid in the area of the main control when the fluid expands due to temperature. When the fluid is cold, the valve allows more fluid from the main control area to return to the sump.

The transmission fluid level check is correctly carried out when fluid temperature is hot.

Main Control








The hydraulic system has a main control assembly. The pump assembly, hydraulic control valves and electro-hydraulic actuators are located in the main control.

Gaskets are used for the separator plate between the pump body and valve body. The separator plate between the valve body and chain cover has integral gaskets.

Accumulators
The hydraulic system has accumulators in circuits for five apply components. Each accumulator has a piston (with seal and spring) positioned on a hollow shaft. The low-intermediate (N-D) accumulator is located in the bottom of the transaxle case. The chain cover and side of the transaxle case contain four accumulators:
^ reverse (N-R)
^ intermediate (1-2)
^ direct (2-3)
^ overdrive (3-4)
