RECONDITION SUB-ASSEMBLIES
The following procedures cover the disassembly,
inspection, repair, and assembly of each sub-assem-
bly as removed from the transmission.
Heli-Coil inserts are recommended for repairing
damaged, stripped or worn threads in aluminum
parts. Refer to Page 49.
Pre-sized service bushings are available for replace-
ment for most all bushings in the TorqueFlite trans-
mission. The two bushings in the sun gear are not

serviced because of the low cost of the sun gear as-
sembly. If the bushings are found worn or scored,
they should be replaced as outlined in the following
reconditioning procedures.
The bushing replacement tools listed by "SP" num-
bers are part of Tool Kit C-3887.
The use of crocus cloth is permissible where neces-
sary, providing it is used carefully. When used on the
valves, use extreme care to avoid rounding off the
sharp edges. The sharp edge is vitally important to
this type valve. Sharp edges prevent dirt and foreign
matter from getting between the valve and body, thus
reducing the possibilities of sticking. When it be-
comes necessary to recondition the transmission, and
the vehicle has accumulated considerable mileage, in-
stall new seal rings on parts requiring their usage.
NOTE: Coat each part with Automatic Transmis-
sion Fluid Type
" A Suffix "A" during assembly.
VALVE BODY ASSEMBLY
Disassembly
CAUTION: Never clamp any portion of the valve
body or transfer plate in a vise. Any slight distor-
tion of the aluminum body or the transfer plate
will result in sticking valves, excessive leakage or
both. When removing or installing valves or plugs,
slide them in or out carefully. Do not use force.
(1)
Place the valve body assembly on repair stand,
