7. WARNING: When using compressed air, never let air pressure exceed 172 kPa (25 psi) and always wear safety glasses. Compressed air may cause foreign material or parts to become airborne. Failure to follow this instruction may result in serious 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.
