INPUT SHAFT END PLAY CHECK
NOTE: Overdrive unit must be installed in order to
correctly measure the input shaft end-play.
(1) Measure input shaft end play (Fig. 62).
NOTE: If end play is incorrect, transmission is
incorrectly assembled, or reaction shaft thrust
washer is incorrect. The reaction shaft thrust
washer is selective.
(a) Attach Adapter 8266-5 to Handle 8266-8.
(b) Attach dial indicator C-3339 to Handle
8266-8.
(c) Install the assembled tool onto the input
shaft of the transmission and tighten the retaining
screw on Adapter 8266-5 to secure it to the input
shaft.
(d) Position the dial indicator plunger against a
flat spot on the oil pump and zero the dial indica-
tor.
(e) Move input shaft in and out and record read-
ing. End play should be 0.86-2.13 mm (0.034-0.084
in.). Adjust as necessary.
ACCUMULATOR, VALVE BODY, OIL PAN, AND
TORQUE CONVERTER
(1) Install accumulator inner spring, piston and
outer spring (Fig. 63).(2) Verify that park/neutral position switch has
notbeen installed in case. Valve body can not be
installed if switch is in position.
(3) Install new valve body manual shaft seal in
case (Fig. 64). Lubricate seal lip and manual shaft
with petroleum jelly. Start seal over shaft and into
case. Seat seal with 15/16 inch, deep well socket.
(4) Install valve body as follows:
(a) Start park rod into park pawl. If rod will not
slide past park pawl, pawl is engaged in park gear.
Rotate overdrive output shaft with suitable size 12
point socket; this will free pawl and allow rod to
engage.
(b) Align and seat valve body on case. Be sure
manual lever shaft and overdrive connector are
fully seated in case.
(c) Install and start all valve body attaching
bolts by hand. Then tighten bolts evenly, in a diag-
onal pattern to 12 N´m (105 in. lbs.) torque.Do
not overtighten valve body bolts. This could
result in distortion and cross leakage after
installation..
(5) Install new filter on valve body. Tighten filter
screws to 4 N´m (35 in. lbs.).
(6) Install seal on park/neutral position switch.
Then install and tighten switch to 34 N´m (25 ft.
lbs.).
CAUTION: If the condition of the transmission
before the overhaul procedure caused excessive
metallic or fiber contamination in the fluid, replace
the torque converter and reverse flush the cooler(s)
and cooler lines. Fluid contamination and transmis-
sion failure can result if not done.
(7) Install torque converter. Use C-clamp or metal
strap to hold converter in place for installation.

straightedge (Fig. 65). Surface of converter lugs
should be 1/2 in. to rear of straightedge when con-
verter is fully seated.
(7) Temporarily secure converter with C-clamp.
(8) Position transmission on jack and secure it
with chains.
(9) Check condition of converter driveplate.
Replace the plate if cracked, distorted or damaged.
Also be sure transmission dowel pins are seated
in engine block and protrude far enough to
hold transmission in alignment.
