GM Service Manual Online
For 1990-2009 cars only

The vehicle has an automatic transaxle shiftlock control system which locks the shift lever in PARK (P) when the ignition is in the OFF position. The regular brakes have to be fully applied before the vehicle can be shifted from PARK (P) when the ignition is in RUN. See Automatic Transaxle Operation .

If the vehicle cannot be shifted out of PARK (P), ease pressure on the shift lever and push the shift lever all the way up into PARK (P) as brake application is maintained. Then move the shift lever into the desired gear.

If the brake pedal is held down but still cannot be shifted out of PARK (P), try this:

  1. Turn the ignition key to ACCESSORY. There is no shift interlock in this key position.
  2. Apply and hold the brake until the end of Step 4.
  3. Shift the transaxle to NEUTRAL (N).
  4. Start the vehicle and then shift to the desired gear.
  5. Have the system fixed as soon as possible.
