(4) Install vehicle speed sensor in speedometer
adapter. Tighten sensor attaching screw to 2-3 N-m
(15-27 in. lbs.) torque.
(5) Install speedometer pinion in adapter.
(6) Count number of teeth on speedometer pinion.
Do this before installing assembly in housing. Then
lubricate pinion teeth with transmission fluid.
(7) Note index numbers on adapter body (Fig. 9).
These numbers will correspond to number of teeth on
pinion.
(8) Install speedometer assembly in housing.
(9) Rotate adapter until required range numbers
are at 6 o-clock position. Be sure range index num­
bers correspond to number of teeth on pinion gear.
(10) Install speedometer adapter clamp and retain­
ing screw. Tighten clamp screw to 10-12 N-m (90-110
in. lbs.) torque.
(11) Connect wires to vehicle speed sensor.
(12) Lower vehicle.
ADAPTER REMOVAL
(1) Raise vehicle.
(2) If adapter is to be removed for disassembly and
overhaul, remove drain plug and drain lubricant from
adapter.
(3) Disconnect vehicle speed sensor wires at sensor

Fig. 10 Shift Rod And Speed Sensor Wire Attachment
(4) Disconnect shift rod from grommet in adapter
shift lever (Fig. 10). Use channel lock-style pliers to
press rod out of grommet.
(5) Mark propeller shaft yoke for alignment refer­
ence. Then disconnect and remove propeller shaft.
(6) Remove nuts securing adapter mounting studs
to transmission extension (Fig. 11).
(7) Slide adapter studs out of transmission exten­
sion and remove adapter from vehicle.
(8) If a gasket is used between adapter and trans­
mission, retain gasket if in good condition.
ADAPTER INSTALLATION
(1) If adapter was overhauled, fill adapter to bot­
tom edge of fill plug hole with Mopar Dexron II, or
ATF Plus transmission fluid. Tighten fill plug to
41-54 N*m (30-40 ft. lbs.) torque.
(2) Clean mounting surfaces of adapter and trans­
mission extension with solvent.
(3) Apply 2-3 drops of Mopar Lock N' Seal, or Loc­
tite 242 to adapter mounting nuts.
(4) Install gasket on adapter (if equipped). Apply
thin bead of sealer to transmission extension and to
gasket, if used.
(5) Install adapter on transmission and install
adapter mounting nuts. If adapter has 5/16 studs,
tighten nuts to 30-41 N-m (22-30 ft. lbs.). If adapter
has 3/8 studs, tighten nuts to 41-47 N-m (30-35 ft.
lbs.).
(6) Lubricate propeller shaft slip yoke with trans­
mission fluid or petroleum jelly.
(7) Align and install propeller shaft. Tighten shaft
clamp bolts to 19 N-m (170 in. lbs.) torque.
(8) Connect shift rod to adapter shift lever. Be sure
rod is fully seated in plastic grommet.
(9) Adjust shift rod if necessary.
(10) Lower vehicle.
