Clean the case in a solvent tank. Flush the case
bores and fluid passages thoroughly with solvent.
Dry the case and all fluid passages with compressed
air. Be sure all solvent is removed from the case and
that all fluid passages are clear.
NOTE: Do not use shop towels or rags to dry the
case (or any other transmission component) unless
they are made from lint-free materials. Lint will
readily adhere to case surfaces and transmission
components and will circulate throughout the trans-
mission after assembly. A sufficient quantity of lint
can block fluid passages and interfere with valve
body operation.

Inspect the case for cracks, porous spots, worn
servo bores, or damaged threads. However, the case
will have to be replaced if it exhibits damage or wear.
Lubricate the front band adjusting screw and lock-

the case. Be sure the screw turns freely and does not
bind. Install the locknut on the screw after checking
screw thread operation.
Inspect all the transmission bushings during over-
haul. Bushing condition is important as worn, scored
bushings contribute to low pressures, clutch slip and
accelerated wear of other components. Replace worn,
or scored bushings, or if doubt exists about bushing
condition.
Use recommended tools to replace bushings. The
tools are sized and designed to remove, install and
seat bushings correctly. The bushing replacement
