PARTS REPAIR
AND

REPLACEMENT

During
the
repair
of the sub-

assemblies, certain general instructions

which apply
to all
units
of the
trans-

mission must
be
followed. These
in-

structions
are
given here
to
avoid
un-

necessary repetition.

Handle
all
transmission parts care-

fully
to
avoid nicking
or
burring
the

bearing
or
mating surfaces.

Lubricate
all
internal parts
of the

transmission with transmission fluid

before assembly.
Do
not use any
other

lubricants except
on
gaskets
and

thrust washers which
may be
coated

with vaseline
to
facilitate assembly.

Always install
new
gaskets when
as-

sembling parts
of the
transmission.

Tighten
all
bolts
and
screws
to the

recommended torque.

detail

cleaning
and
inspection operations

ces.

Lubricate all internal parts of the

transmission with clean automatic

transmission fluid before assembling

them.

Do not use any other lubricants ex-

cept on gaskets and thrust washers.

These may be coated with vaseline to

facilitate assembly. Always use new

gaskets and seals when assembling a

transmission.
Tighten all bolts and screws to the

recommended torque as outlined in

the Specification Section.

moval of the plug and the 3-2 shift

timing valve. This condition will not

affect transmission operation and is

not cause for replacement of the main

control. The 3-2 shift timing valve is

non-functional and removal of the
