INSTALLATION
Note the following, and install in the reverse order of removal.

After installation is completed, adjust and check A/T position. Refer to AT- 2 3 5 , "Adjustment of A/T Posi-
tion" and AT- 2 3 5 , "Checking of A/T Position" .
Adjustment of A/T PositionACS002RR
1. Loosen nut of control rod.
2. Place PNP switch and selector lever in “P” position.
3. While pressing lower lever toward rear of vehicle (in “P” position direction), tighten nut to specified torque.
CAUTION:
Do not push the bracket.
Checking of A/T PositionACS002RS
1. Place selector lever in “P” position, and turn ignition switch ON (Do not start engine).
2. Check selector lever can be shifted to other than “P” position when brake pedal is depressed. Also check selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Check the selector lever stops at each position with the feel of engagement when it is moved through all the positions. Check whether or not the actual position the selector lever is in matches the position shown
by the shift position indicator and the transmission body.
5. The method of operating the lever to individual positions cor- rectly should be as shown in the figure.
6. When selector button is pressed in “P”, “R”, or “N” position with- out applying forward/backward force to selector lever, check but-
ton operation for sticking.
7. Check the back-up lamps illuminate only when lever is placed in the “R” position. Check the back-up lamps does not illuminate
when selector lever is pushed against “R” position in the “P” or
“N” position.
8. Check the engine can only be started with the selector lever in the “P” and “N” positions.
9. Check transmission is locked completely in “P” position.
10. When selector lever is set to manual shift gate, check manual mode is displayed on combination meter. Shift selector lever to “+” and “-” sides, and check set shift position changes. : 26 N·m (2.7 kg-m, 19 ft-lb)

A/T SHIFT LOCK SYSTEM
Revision: 2005 July 2005 FX
A/T SHIFT LOCK SYSTEMPFP:34950
DescriptionACS002RT

The mechanical key interlock mechanism also operates as a shift lock:
With the ignition switch turned to ON, the selector lever cannot be shifted from “P” position to any other
position unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from “P” position to any other position.
The key cannot be removed unless the selector lever is placed in “P” position.

The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and slider located inside the key cylinder.
