General Assembly Notes:

The automatic transmission is composed of highly precision-finished parts, necessitating careful inspection before assembly because even a small nick could cause fluid leakage or affect performance.
Before assembling new clutch discs and brake bands, soak them in automatic transmission fluid for at least thirty minutes.
Apply automatic transmission fluid on the sliding or rotating surfaces of parts before assembly.
Use petroleum jelly to keep small parts in their places.
Do not use adhesive cements on gaskets and similar parts.
When assembling the transmission, be sure to use new gaskets and O-rings.
Dry all parts with compressed air - never use shop rags.
Be sure to install the thrust bearings and races in the correct direction and position.
