WARNING: In order to avoid injury, eye protection should be worn when cleaning components with compressed air. Failure to follow these instructions may result in personal injury.

NOTE: Clean all components with a suitable solvent and use moisture free compressed air to dry all parts and clean fluid passages.

Inspect the converter housing for:
- Stator support area wear
- Case mating surfaces for nicks or deformation
- Differential bushing wear
Check the converter housing hydraulic passages for blockage.
1. Differential lubrication passage
2. Front lubrication passage
3. Converter turbine passage
4. Converter impeller passage
5. Cooler passage
