Inspection Procedure

Notice: Before you overhaul the transaxle, clean the exterior thoroughly in order to protect its inner components against dust and dirt. Keep the transaxle in an upright position with the fluid pan on the bottom until all of the fluid has been drained from the transaxle. If you turn the transaxle on its side or over before the fluid stops draining, clutch material or other foreign matter may contaminant the fluid passages of the valve body and case. Failure to follow this precaution may result in unnecessary valve body overhaul.

  1. Inspect the rings for cuts or restricted movement in the ring grooves.
  2. If the rings are damaged, inspect the ring grooves for debris or burrs.
  3. Inspect the thrust washer surfaces for damage. The thrust washer and the thrust bearing surfaces may appear to be polished. This is a normal condition.

Removal Procedure
