Major Components
Disassembly, inspection and reassembly of each
component group is indicated in the following chapter.
Before reassembly, make sure, again, that all
component groups are assembled correctly.
If something wrong is found in a certain component
group during assembly, inspect and repair this group
immediately.
General Assembly Notes:
1. 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.


2. Before assembling new clutch discs and brake
bands, soak them in automatic transmission fluid fo
r
at least thirty minutes.
3.
Apply automatic transmission fluid on the sliding or
rotating surfaces of parts before assembly.
4. Use petroleum jelly to keep small parts in thei
r
palces.
5. Do not use adhesive cements on gaskets and similar parts.
6. When assembling the transmission, be sure to use new gaskets and O-rings.
7. Dry all parts with compressed air - never use shop rags.
8. Be sure to install the thrust bearings and races in the correct direction and position.
