1. Remove transmission support to transmission mount
bolts and transmission support to frame bolts.
12. Raise transmission with a jack and remove support.
13.
Lower
transmission
slightly
and
remove
transmission to engine bolts.
14. Lower transmission being careful not to damage
cooler lines, T.V. cable and shift linkage.
15. If transmission is to be moved, install converter
holding Tool J 2 1366.
Installation
1. Place transmission on locating pilots. Install
downshift cable into clip on transmission. insert oil filler tube
and bolt tube in place. Install transmission to engine bolts and
torque to 54 N - m (40 lb. ft.).
NOTE: Rotate converter to permit coupling of flywheel
and converter in the original position by aligning the
marks made before removal.
2. Install transmission support and torque support to
frame nuts to 34 N . m (25 lb. ft.). Torque support to
transmission mount bolts to 61 N - m (45 Ib. ft.). Remove
engine support bar.
NOTE: Make sure parking brake cable is above the
support.
3. Install shift linkage.
4. Install 3 converter to flywheel bolts and torque to 41
N - m (30 lb. ft.). Install transmission flywheel cover pan.
5. Install T.V. cable to link. Install cable housing into
transmission case and torque retaining bolt to 10 N - m (8 lb.
ft
.).
6. Reconnect catalytic converter support bracket at
transmission. Torque nuts to 47 N - m (35 lb. ft.) at
transmission and U-bolt.
NOTE: This transmission is easily identified by the word
METRIC stamped on the bottom pan.
NOTE: To hold the torque converter from falling during
transmission removal, secure converter by drilling hole
in J 21366 tool on the 90mm (3-1/2") step side to line
up with converter lug bolt hole and retain with bolt. (Fig.
7A1-18)
TRANSMISSION DISASSEMBLY
Removal of Converter
1. With transmission in cradle of portable jack, remove
J 21366 and then converter assembly by pulling straight out.
2. Installing Holding Fixture, J 8763-02 on transmission
and place into Holding Fixture, J 3289-20, with manual shaft
facing bench and oil pan side up (Fig. 7A1-18).
CAUTION: Do not over torque fixture holding
screw.
NOTE: Cleanliness is an important factor in the
overhaul of the transmission. Before attempting any
disassembly operation, the exterior of the transmission
should be thoroughly cleaned to prevent the possibility
of dirt entering the transmission internal mechanism.
During inspection and re-assembly, all parts should be
-

Transmission in Holding Fixture
thoroughly cleaned with cleaning fluid and then air
dried. wiping cloths or rags should not be used to dry
parts.
CAUTION: Do not use solvents on neoprene
seals, composition-faced clutch plates or thrust
washers.
TEFLON SEALS
If any teflon seal rings are damaged (distorted, cut,
scored, etc.), or do not rotate freely in their groove, and
replacement is necessary, do the following:
1. Remove and discard old angle cut seal rings; full circle
rings must be cut off.
2. Inspect seal ring groove for burrs or damage.
3.When installing angle cut seal rings, do not over-
stretch. Make sure cut ends are in same relation as cut. (Fig.
7A1-19) Also, make sure rings are seated in the grooves to
prevent damage to the rings during resasembly of mating part
over rings. Retain with petrolatum.
4. New angle cut or full circle teflon seal rings may
appear to be distorted after being installed. Once exposed to
normal transmission oil temperatures, the new seal rings will
return to their normal shape and fit freely in their bores.
5. The teflon seal rings allow for a free fit in their bores
after operation. The free fit of the rings in their bores does
not indicate leakage during operation.
SNAP RINGS
Do not over expand snap rings when removing or
installing.
THRUST WASHER SURFACES
The thrust washers and thrust bearings will polish the
surface they protect. This is not to be considered a damaged
part because of this condition.
