AUTOMATIC TRANSMISSION
REASSEMBLY
Assembly cautions
Use your bare hands or vinyl gloves to reassemble the
transmission. Do not use ordinary work gloves (loosen
threads from the gloves may fall into the transmission
and cause problems).
Before installing the drive plates, immerse them in the
recommended automatic transmission fluid (BESCO
ATF II or ATF III). If the drive plate is new, it must be
immersed for at least two hours to ensure oil penetration
and saturation of the facing.
Apply ATF to all sliding and contact surfaces before
assembly. Also apply ATF to seal rings and O-rings.
Assemble the parts carefully to avoid damaging them.
Replace any snap ring that appears worn, bent out o
f
shape, or otherwise damaged.
If any part contacting the transmission case is damaged,
it must be replaced with a new part.
Be careful not to damage the plates during reassembly
(oil leakage from the plate will result).
If you are reusing a seal, remove the old adhesive agen
t
and clean the surface with cleaning oil before applying
the new adhesive agent.
Wait at least two hours after installing the oil seals
before installing the plates.
Do not replace O-rings, snap rings, bearings, and/o
r
bearing races with inferior substitutes.
