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.

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.
