TRANSMISSION ASSEMBLY PREPARATION
Do not allow dirt, grease, or foreign material to
enter the case or transmission components during
assembly. Keep the transmission case and compo-
nents clean. Also make sure the tools and workbench
area used for assembly operations are equally clean.
Shop towels used for wiping off tools and hands
must be made from lint free material. Lint will stick
to transmission parts and could interfere with valve
operation, or even restrict fluid passages.
Lubricate
the
transmission
components
with
Mopar transmission fluid during reassembly. Use
Mopar Door Ease, or Ru-Glyde on seals and O-rings
to ease installation.
Petroleum jelly can also be used to hold thrust
washers, thrust plates and gaskets in position during
assembly. However, do not use chassis grease, bear-
ing grease, white grease, or similar lubricants on any
transmission part. These types of lubricants can
eventually block or restrict fluid passages and inter-
fere with valve operation. Use petroleum jelly only.
Do not force parts into place. The transmission
components and subassemblies are easily installed by
hand when properly aligned.
If a part seems extremely difficult to install, it is
either misaligned or incorrectly assembled. Also ver-
ify that thrust washers, thrust plates and seal rings
