Place selector lever in “P” position, and turn ignition switch ON (engine stop).

Confirm that the selector lever stops at each position by feeling the engagement when it is moved through
all the positions. Check whether or not the actual position the selector lever matches the position shown
by the shift position indicator and the A/T body.

The method of operating the lever to individual positions cor-
rectly is shown in the figure.

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.
