for proper adapter alignment and speedometer oper-
ation.
(2) Install new O-rings on speed sensor and speed-
ometer adapter if necessary (Fig. 76).
(3) Lubricate sensor and adapter O-rings with
transmission fluid.
(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. 77).
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 and top off transmission fluid
level, if necessary.
PARK/NEUTRAL POSITION SWITCH
REMOVAL
(1) Raise vehicle and position drain pan under
switch.
(2) Disconnect switch wires.
(3) Remove switch from case.
