TRANSMISSION PARTS CLEANING AND
INSPECTION Clean the transmission components with solvent
and dry them with compressed air only. Do not use
shop towels or rags.
Blow compressed air through all oil feed passages
and channels to be sure they are clear. Inspect the
transmission components for wear and damage.
Replace components that are damaged or worn
beyond the limits specified in the individual overhaul
procedures.
Replace all O-rings, gaskets and seals. These components
are not reusable. Also replace any snap ring
that is distorted or damaged.
During overhaul assembly operations, lubricate the
transmission components with Mopar Mercony automatic
transmission fluid or petroleum jelly as indicated.
Petroleum jelly should be used to prelubricate
thrust bearings, washers and races. It can also be
used to hold parts in position during assembly.
Soak replacement clutch and brake pack
components in transmission fluid for at least 30
minutes before installation. Check adjustment by starting the engine in Park
and Neutral. Adjustment is OK if the engine starts
only in these positions. Adjustment is incorrect if the
engine starts in one but not both positions. If the
engine starts in any position other than Park or Neutral,
or if the engine will not start at all, the park/
neutral position switch may be faulty. Gearshift Adjustment Procedure (1) Shift transmission into Park.
(2) Raise vehicle.
(3) Release cable adjuster clamp (at transmission
end of cable) to unlock cable.
(4) Unsnap cable from cable mounting bracket on
transmission (Fig. 300).
(5) Slide cable eyelet off transmission shift lever.
(6) Verify transmission shift lever is in Park
detent by moving lever fully rearward. Last rearward
detent is Park position.
(7) Verify positive engagement of transmission
park lock by attempting to rotate propeller shaft.
Shaft will not rotate when park lock is engaged.
(8) Slide cable eyelt onto transmission shift lever.
(9) Snap shift cable adjuster into mounting
bracket on transmission.
(10) Lock shift cable by pressing cable adjuster
clamp down until it snaps into place.
(11) Lower vehicle and check engine starting.
Engine should start only in Park and Neutral.
1 - THROTTLE VALVE CABLE (1) Shift transmission into PARK.
(2) Remove shift lever bezel and console screws.
Raise bezel and console for access to cable.
(3) Pull cable lock button up to release cable (Fig.
301).
(4) Turn ignition switch to LOCK position.
(5) Use a spacer to create a one millimeter gap
between the shifter pawl and top of the shift gate.
(6) Pull cable forward. Then release cable and
press cable lock button down until it snaps in place.
(7) Check adjustment as follows:
(a) Check movement of release shift handle button
(floor shift) or release lever (column shift). You
should not be able to press button inward or move
column lever.
(b) Turn ignition switch to RUN position.
(c) Shifting out of park should not be possible.
(d) Apply the brake and attempt to shift out of
PARK. Shifting should be possible.
(e) While the transmission is shifted out of
PARK, release the brake and attempt to shift through all gears. Release the
shift button at least
once during this procedure. The ignition key should
not go to the LOCK position.
1 - PARK LOCK CABLE (f) Return transmission to the PARK position
without applying the brake.
(8) Move shift lever back to PARK and check ignition
switch operation. You should be able to turn
switch to LOCK position and shift lever release button/
lever should not move. (1) Shift transmission into Park, shut engine off
and raise hood.
(2) Press cable release button (Fig. 302).
(3) Push cable conduit back into cable sheath as
far as possible (Fig. 303).
(4) Rotate lever on throttle body to wide open
throttle position. Cable will ratchet to correct adjustment
point as lever is rotated (Fig. 303).
