TRANSMISSION REASSEMBLY
GENERAL
Before starting to assembly transmission, make certain
that all parts are absolutely clean. Keep hands and
tools clean to avoid getting dirt into assembly. If work
is stopped before assembly is completed, cover all
openings with clean cloths.
Lubricate all bearings, seal rings, clutch plates and
other moving parts with transmission fluid prior to re
assembly. Thrust washers may be held in place with
petroleum jelly, sparingly applied.
Do not take chances on used gaskets and seals
-
use
new ones to avoid oil leaks.
