(1kg, 2.2 lb), release it. This is in the natural state, tighten nut to
the specified torque. Refer toAT- 2 1 0 , "
COMPONENTS".
Checking of A/T PositionECS00G2Y
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 selector lever and check for excessive effort, sticking, noise or rattle.
4. Check 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 selector lever is in matches the position shown by the
shift position indicator and the A/T body.
5. The method of operating the selector lever to individual posi-
tions correctly 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 back-up lamps illuminate only when selector lever is
placed in the “R” position. Check back-up lamps does not illumi-
nate when selector lever is pushed against “R” position in the
“P” or “N” position.
8. Check engine can only be started with selector lever in the “P”
and “N” positions.

A/T SHIFT LOCK SYSTEM
A/T SHIFT LOCK SYSTEM
PFP:34950
DescriptionECS00G2Z
lThe mechanical key interlock mechanism also operates as a shift lock:
With the ignition switch turned to ON, selector lever cannot be shifted from “P” position to any other posi-
tion unless brake pedal is depressed.
With the key removed, selector lever cannot be shifted from “P” position to any other position.
The key cannot be removed unless selector lever is placed in “P” position.
lThe shift lock and key interlock mechanisms are controlled by ON-OFF operation of the shift lock solenoid
and by the operation of the rotator and slider located inside the key cylinder, respectively.
