Test Description

WARNING: This page is about a different variant/trim than selected.

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

  1. 2:  A static shift test is performed by shifting into all gear positions with the engine not operating. While performing the test, slowly move the shift lever. Feel for proper movement of the shift lever and transaxle internal shift components.
  2. 5:  A dynamic shift test is performed by shifting into all gear positions with the engine operating. Test for the correct mesh of the synchronizers sleeve and the speed gear selector teeth. Move the shift lever, and feel for the synchronizer sleeve to release form the gear, and then let up on the clutch pedal. Depress the clutch pedal and move the shift lever to engage the gear again, to ensure full travel of the shift components.
  3. 6:  This step inspects for worn or damaged transaxle or engine mounts. Loose mounts may cause a shock on the transaxle allowing for gear disengagement.
  4. 7:  This step inspects for the misalignment of the clutch to transaxle. Misalignment may put a bind on the input shaft, allowing for the input shaft or the mainshaft to tip.
  5. 9:  This step inspects the pilot bearing and the pilot bearing journal on the input shaft. A worn pilot bearing or input shaft may allow the input shaft to tip, causing gear disengagement.

5 
  1. Perform a dynamic shift test on the transaxle.
  2. Test for the following:
    • Synchronizer sleeve engagement to the speed gear selector teeth
    • Detent plungers engaging in the shift rails
Did the transaxle shift completely into all gears?		 Go to Step 6  Go to Step 9 
6  Inspect the engine and/or transaxle mounts. Refer to Engine Mount Inspection in Engine Mechanical - 2.2L and Transmission Mount Inspection.

    • The shift forks
    • The synchronizer sleeve and speed gear selector teeth
    • The mainshaft to input shaft bearing and journals
    • The speed gear bearings and journals
    • The speed gear axial clearance
    • The mainshaft center and rear bearings
Did you find and repair the condition?		 Go to Step 11  Go to Diagnostic Aids
11 Operate the system in order to verify the repair.
