40. Case Inspection

Notice: Use Transjel J 36850 or equivalent during assembly in order to retain checkballs or to lubricate components. Greases other than the recommended assembly lube will change the transmission fluid characteristics and will cause undesirable shift conditions or filter clogging.

Important: After cleaning the transmission case, allow the case to air dry. Do not use cloth or paper towels in order to dry the transmission case or any other transmission components. Lint from the towels can cause component failure.

1. Thoroughly clean the transmission case and all the case threads with solvent.
2. Inspect the case exterior and the external bores for cracks, sharp edges, porosity and excessive bushing wear.
3. Inspect the case interior for damage at the snap ring grooves, case lugs and band anchor pin.
4. Inspect all the gasket surfaces for surface damage and in order to ensure surface flatness.
5. Inspect the corresponding gasket for proper impressions in order to ensure surface flatness.
6. Inspect the bolt holes and fasteners for thread damage. If necessary, repair or replace any bolt holes or fasteners.
7. Air check the oil passages. For identification of the oil passages, refer to the transmission diagnosis.
