'03 Civic won't park

On level ground, when shifted to maximum forward position with indicator showing R, release the handbrakes and try to push vehicle forward, can vehicle be moved?

If not, the gear shift is correct, the Paark Neutral Position switch is out of adjustment.

If vehicle can be moved, the gear shift is not correct and you would need to check the cable condition and adjustment.

Reconfirm that vhicle cannot be moved when shift lever is in PARK though the indicator is showing R.

The following procedure explains how to replace the transmission range switch. Use only applicable steps for adjustment.
