Automatic Transmission Shift Lock Actuator Replacement
| IMPORTANT | After assembling the shift lock actuator, turn the ignition forward but do not start (auxiliary position) and attempt to pull the lever from PARK with and without the brake pedal depressed to verify there is no gear access without the brake pedal depressed. |
| IMPORTANT | Ensure the key cannot be removed from the ignition unless both the shiftier is in PARK and the shift knob button has been depressed. |

- Remove the console. Refer to «Console Replacement»(ref-268082-S14338351492007101800000) .
- Disconnect the shift lock actuator (3) electrical connector.
- Shift assembly to the LOW position.
- Loosen and remove the screw at the rear of the shiftier assembly.
- Shift the assembly to the NEUTRAL position.
- Loosen and remove the top screw of the shift lock actuator through the lever slot.
- Pull lever to the DRIVE position and remove the shift lock actuator.
Installation Procedure
- In DRIVE position, depress the shift lock actuator button and realign into the shiftier lever.
- Push lever to NEUTRAL. NOTE: Refer to «Fastener Notice»(ref-268087-S07010920292007101800000) .
- Install the top screw through the lever slot. Tighten: Tighten the actuator screw to 1.65 N.m (15 lb in).
- Shift lever to LOW.
- Install the screw at the rear of the shiftier assembly. Tighten: Tighten the actuator screw to 1.65 N.m (15 lb in).
- Connect the electrical connector (3).
- Verify the shift lock actuator functions properly.
- Install the console. Refer to «Console Replacement»(ref-268082-S14338351492007101800000) .
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components
- The automatic transmission shift lock control solenoid
- The automatic transmission shift lock control switch
With the ignition in the ON position, voltage is supplied to automatic transmission shift lock control switch. Voltage flows through the normally closed contacts of the automatic transmission shift lock control switch to the automatic transmission shift lock control solenoid. The automatic transmission shift lock control solenoid is permanently grounded. This energizes the automatic transmission shift lock control solenoid causing the transmission shift lever to be physically locked in the PARK position. When the brake pedal is pressed the contacts in the automatic transmission shift lock control switch open, de-energizing the automatic transmission shift lock control solenoid. This allows the shift lever to be move out of the PARK position.
