Preliminary Check Procedure

Pressure Check Chart:

Check the transaxle fluid to make sure that it is at the proper level. Note the fluid color. Burned fluid loses its red color and has an acrid odor.

NOTICE: IF THE OIL IS BURNED AND/OR CLUTCH PLATE MATERIAL IS FOUND IN THE OIL PAN, REQUEST A REPLACEMENT TRANSAXLE.

CHECK AND ADJUST T.V. CABLE

CHECK OIL PRESSURES IN THE FOLLOWING MANNER:

Minimum Line Pressure Check With the parking brake and vehicle brakes applied, take the line pressure readings in the ranges and at the engine r.p.m.'s indicated in the chart below.

Full Line Pressure Check Full line pressure readings are obtained by removing the vacuum line from modulator, and with the parking brake and vehicle brakes applied, take the line pressure readings in the ranges and at the engine r.p.m.'s indicated in the chart below.

NOTICE Total running time not to exceed 2 minutes.

CAUTION Brakes must be applied at all times.

Line pressure is basically controlled by pump output and the pressure regulator valve. In addition, line pressure is boosted in Reverse, and Lo by the reverse boost valve.

Also, in the Neutral, Drive and Reverse positions of the selector lever, the line pressure should increase with throttle opening because of the vacuum modulator.

*The VRV Valve on Diesel engines must operate properly.
Refer to the appropriate service manual section for complete service procedures. Do not attempt to repair porous or cracked cases.
