section 1).
1. Remove the front console (see section Z0l.
2. Shift to @ position. then remove the lock pin fromthe adiuster.

3. Check that the hole in the adjuster is perfectlyaligned with the hole in the shift cable. There aretwo holes in the adjuster. They are positioned 90.apart to allow cable adjustment in 1/4 turn incre-ments.
ExactAlignment
4. lf the hole is not perfectly aligned, loosen the lock-nut on the adjuster and adjust as required.
5. Tighten the tocknut to 7 N.m (0.7 kgf.m, 5 tbf.ft).
6. Install the lock pin on the adjuster. lf you feel thelock pin binding as you reinstall it, the cable is stillout of adjustment and must be readjusted.
7. Make sure the lock pin is seated in the adjustersecuretv.
8. Move the shift lever to each gear, and verify that theshift position indicator follows the automatic trans-axle gear position switch.
9. Start the engine, and check the shift lever in allgears. lf any gear does not work properly, refer totroubleshooting (see page 14-109 thru 1'4-'112).
10. Insert the ignition key into the key cylinder on theAy'T gear position indicator panel, and verify that theshift lock lever is released.
