1. Disconnect lower lever of control device and control rod.
2. Remove manual lever from A/T assembly.
3. Remove control rod from vehicle.
INSTALLATION
Install in reverse order of removal. Be careful of the following:
 After installation is completed, adjust and check A/T position. Refer to AT-207, "
Adjustment of A/T Position"
and AT-207, "Checking of A/T Position".
Adjustment of A/T PositionINFOID:0000000001327385
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 the specified torque. Refer to AT-206,
"Control Rod Removal and Installation".
CAUTION:
Do not push the bracket.
Checking of A/T PositionINFOID:0000000001327386
1. Place selector lever in “P” posit ion, and turn ignition switch ON.
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 wit h the feel of engagement when it is moved through all
the positions. Check whether or not t he 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. (With selector lever in the “P” position,
engine can be started even when selector lever is moved for-
ward and backward.)
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. (Only while a vehicle is oper-
ating.)

A/T SHIFT LOCK SYSTEM
A/T SHIFT LOCK SYSTEM
DescriptionINFOID:0000000001327387
 The mechanical key interlock mechanism also operates as a shift lock:With the ignition switch turned to ON, the selector le ver cannot be shifted from “P” position to any other posi-
tion 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 contro lled 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.
