Test Description

The numbers below refer to the step numbers on the diagnostic table.

  1. This step is to ensure the use of the proper transaxle fluid. A special fluid is used to ensure proper synchronizer operation, and for sufficient lubrication. Improper fluid may cause the synchronizers to stick or the transaxle components to overheat.

  2. A static shift test is performed by shifting into all gears with the engine not operating. By confirming that the transaxle can be shifted into all positions, ensures that the shift lever is not excessively worn or damaged.

    3.

  3. A dynamic shift test is performed by shifting into all of the gear positions with the engine operating. Test to ensure that the internal shift components are functioning properly.
