Automatic Transaxle Shift Lock Control
System Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough room
around the vehicle. It should be parked on a level
surface.
2. Firmly apply the parking brake. SeeParking Brake
on page 2-27if necessary.
Be ready to apply the regular brake immediately if
the vehicle begins to move.
3. With the engine off, turn the key to the ON position,
but don’t start the engine. Without applying the
regular brake, try to move the shift lever out
of PARK (P) with normal effort. If the shift lever
moves out of PARK (P), contact your GM
Goodwrench dealer for service.
Ignition Transaxle Lock Check
While parked, and with the parking brake set, try to turn
the ignition key to OFF in each shift lever position.
•With an automatic transaxle, the key should turn to
OFF only when the shift lever is in PARK (P). The
key should come out only in OFF.
•With a manual transaxle, the key should turn to
OFF only when the shift lever is in reverse. The
key should come out only in OFF.
Contact your GM Goodwrench dealer if service is
required.

{CAUTION:
When you are doing this check, your vehicle
could begin to move. You or others could be

sure there is room in front of your vehicle in

downhill. Keeping your foot on the regular brake, set the
parking brake.
•To check the parking brake’s holding ability: With
the engine running and transaxle in NEUTRAL
(N), slowly remove foot pressure from the regular
brake pedal. Do this until the vehicle is held by the
parking brake only.
•To check the PARK (P) mechanism’s holding
ability: With the engine running, shift to PARK (P).
Then release the parking brake followed by the
regular brake.
Contact your GM Goodwrench dealer if service is
required.

corrosive materials from the underbody. Take care to
clean thoroughly any areas where mud and other debris
