1) Low-reverse band is rear band on transmission. Oil pan
must be removed from transmission to adjust low-reverse band. Raise
and support vehicle. Loosen oil pan bolts. Allow fluid to drain from
oil pan. Remove oil pan bolts, oil pan and gasket.
2) Loosen low-reverse band adjusting screw lock nut while
preventing low-reverse band adjusting screw from rotating. Low-reverse
band adjusting screw lock nut and low-reverse band adjusting screw are
located inside transmission, near low-reverse band. See Fig. 5.
3) Back off low-reverse band adjusting screw lock nut 5
turns. Ensure low-reverse band adjusting screw rotates freely in
transmission case.
4) Tighten low-reverse band adjusting screw to 72 INCH lbs.
(8.1 N.m). Back off low-reverse band adjusting screw specified amount
of turns. See LOW-REVERSE BAND ADJUSTMENT table. Hold low-reverse band
adjusting screw and tighten low-reverse band adjusting screw lock nut
to specification. See TORQUE SPECIFICATIONS.

5) Clean oil pan, magnet and all sealing surfaces. Using NEW
gasket, install oil pan. Install and tighten oil pan bolts to
specification. See TORQUE SPECIFICATIONS.
6) Add Mopar ATF Plus Type 7176 fluid until fluid level is at
MIN arrow mark on dipstick. Start engine and allow engine to idle.
With brakes applied, shift transmission through all gears and back to
Neutral.
7) Add additional fluid to bring fluid level to MIN mark on
dipstick. Recheck fluid level with transmission at normal operating
temperature. Adjust fluid level to MAX arrow mark on dipstick. DO NOT
overfill transmission.

SHIFT CABLE

Dakota & Durango
1) Raise and support vehicle. Ensure shift lever is in Park.
Release shift cable adjuster lock. Shift cable adjuster lock is
located on shift cable, just below brake booster.
2) Disconnect shift cable from transmission shift lever on
transmission. Ensure transmission is still in Park by rotating
transmission shift lever fully toward rear of vehicle to Park detent.
3) Verify parking sprag on transmission is engaged by
attempting to rotate drive shaft. Install shift cable on transmission
shift lever. Lock shift cable in place by pressing shift cable
adjuster lock downward until it snaps into place.
4) To verify proper adjustment, check that engine only starts
with shift lever in Park and Neutral. If engine starts in any other
gears except Park or Neutral, shift cable may be improperly adjusted
or park/neutral position switch may be defective.
Ram Van/Wagon
1) Raise and support vehicle. Ensure shift lever is in Park.
Unsnap shift cable from ball at transmission shift lever on
transmission. See Fig. 6.
2) Check that transmission is still in Park by rotating
transmission shift lever fully toward rear of vehicle to Park detent
position. Release cable adjuster at transmission end of shift cable to
unlock shift cable. See Fig. 6. Snap shift cable back on ball at
transmission shift lever. Press cable lock inward to secure shift
cable.
3) To verify proper adjustment, ensure engine only starts
with shift lever in Park and Neutral. Shift lever should not move from
Park when ignition switch is in LOCK position. Shift lever should move
from Park when ignition switch is in any position except LOCK
position.
