!@ Make sure lifts, jacks and safety stands are
placed properly (see section 1).
l. Remove the front console (see section 20).

3. Check that the hole in the adiuster is perfectly aligned
with the hole in the shift cable. There are two holes in
the adjuster. They are positioned 90" apart to allow
cable adjustment in 1/4 turn increments.
lf the hole is not perfectly aligned, loosen the lock-
nut on the adjuster and adjust as required.
Tighten rhe locknut to 7 N.m (0.7 kgim,5 lbf'ft).
Install the lock pin on the adjuster' lf you feel the
lock pin binding as you reinstall it. the cable is still
out of adjustment and must be readjusted
Make sure the lock pin is seated in the adiuster
securery.
lMove the shift lever to each position, and verify that
the shift position indicator follows the automatlc
transaxle gear position switch.
Start the engine, and check the shift lever in all
positions. lf any gear does not work properly, refer
to troubleshooting (see page 14-294 and 14-295).
Insert the ignition key into the key cylinder on the
Aff gear position indicator panel, and verify that the
shift lock lever is released.
