Adding Fluid to Fill Dry Transmission and
Converter Assembly
In cases of transmission overhaul when a complete fill
is required, including converter (approximately 20 pints),
proceed as follows:
1. Add 8 pints of transmission fluid through filler tube.
2. With manual control lever in park (P) position, start
engine and place on cold idle cam. DO NOT RACE
ENGINE. Move manual control lever through each range.
3. Immediately check fluid level with selector lever in
park (P), engine running and vehicle on LEVEL surface and
add additional fluid to bring level to 1/4-inch below "ADD"
mark on the dipstick. Do not overfill.
INTERMEDIATE BAND ADJUSTMENT
Intermediate band adjustment should be performed
every 60,000 miles with transmission fluid change or sooner,
as necessary, if operating performance indicates intermediate
band slippage.
1. Position selector lever in neutral (N) and raise vehicle.
2. Using Special Tool 5-24367 in position over adjusting
screw and locknut on right side of transmission, loosen
locknut 1/2 turn and hold tool in this position.
3. With a torque wrench attached to special tool, tighten
adjusting screw to 30 inch pounds and back-off 3 complete
turns. Use mark on special tool as indicator.
4. With torque wrench held in position on special tool,
tighten locknut 15 Ib. ft.
CHECKING TRANSMISSION M O U N T
Raise vehicle on a hoist. Push up and pull down on
transmission tailshaft while observing transmission mount. If
rubber separates from metal plate of mount or if tailshaft
moves up but not down (mount bottomed out) replace mount.
If there is relative movement between a metal plate of mount
and its attaching point, tighten screws or nuts attaching
mount to transmission or crossmember.
Shift Control Cable Adjustment (Fig. 7A2-7)
1. Place control shifter assembly " A in neutral position.
2. Loosen nut
"B"
and washer from pin "C" at the
selector lever "D" (View A).
3. Make sure selector lever "D" is in NEUTRAL
position.
NOTE: NEUTRAL can be obtained by moving selector
lever "D" counter clockwise to L1 detent, then move
clockwise through three (3) detent positions to
NEUTRAL.
4. Then, with control shifter assembly "A"
in
NEUTRAL, tighten nut
"B"
to 20 Ib. ft. torque.
5. Readjust neutral start switch if necessary to provide
the correct relationship to the transmission detent positions.
See Section 8.
CAUTION: Any inaccuracies in the above
adjustments may result in premature failure of
transmission due to operation without controls in
full detent. Such operation results in reduced fluid
pressure and in turn partial engagement of
fleeted
