GENERAL INFORMATION
The automatic transmission Shifter/Ignition Inter-
lock, is a mechanically cable operated system (Fig.
1). It interconnects the automatic transmission floor
mounted shifter to the steering column ignition
switch. The interlock system locks the floor mounted
shifter on automatic transmission equipped vehicles
into the PARK position. The Interlock system is en-
gaged whenever the ignition switch is in the LOCK
or ACCESSORY position. When the key is in the
OFF or RUN position the shifter is unlocked and will
move into any position. The interlock system also
prevents ignition switch from being turned to the
OFF or ACCESSORY position, unless shifter is fully
locked into the PARK position.
INTERLOCK SYSTEM OPERATION CHECK
(1) With the shifter in PARK, and the shifter knob
pushbutton in its full up position, the ignition switch should rotate freely from OFF to LOCK position.
When the shifter is moved to the DRIVE (or OVER-
DRIVE) position if so equipped the ignition switch
should not rotate from OFF to LOCK. (2) Moving shifter out of PARK should only be pos-
sible when ignition switch is in the OFF or RUN po-
sition. Movement of the shifter from the PARK
position should not be possible, when the ignition
switch is in the LOCK position. (3) If the automatic transmission Shifter/Ignition
Interlock System operates in any way other than as
described above, diagnosis, adjustment or repair of
the system is required. See Adjustment and Repair
procedures in this section of the service manual.

INTERLOCK SYSTEM ADJUSTMENT
If ignition switch is binding, operating effort high or
can not be turned to the LOCK position, with shifter locked
in PARK, adjustment of Interlock System may be
required. To adjust Interlock System, follow procedure
listed below. (1) Remove the shift knob to shifter retaining screw
and shift knob from shifter (Fig. 2). Leave the shifter
release button in shifter handle.
(2) On the AA and AP bodies, remove PRNDL plate
(Fig. 2) from center console for adjustment of interlock
cable. PRNDL plate is removed by gently prying be-
tween plate and console with a screw driver. Use care
so not to damage plate or console assembly. (3) On the AG and AJ bodies, the center console
(Fig. 3) requires removal from vehicle for adjustment of
interlock cable. Refer to the AG or AJ section of Group
23 Body, in this service manual for detailed center
console removal procedure. (4) Place shifter in PARK, and ensure that the
plunger (Fig. 4) on shifter mechanism is in the full up
position. (5) Turn ignition switch to the ACCESSORY posi-
tion. The Interlock System will not adjust prop-
erly if the ignition switch is in the LOCK position.
If interlock cable has lost its adjustment, it
will be necessary to manually position cable to get
key into Accessory position. Grasp slug on interlock
cable (Fig. 5) with needle nose pliers and pull back
on cable. This will allow the ignition switch to be
turned to the ACCESSORY position. (5) Check that the interlock cable slug is com-
pletely seated into the shifter interlock lever (Fig. 4). (6) Check that the ignition switch is still in the ac-
cessory position (Fig. 1). Loosen the shifter interlock
