Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Shifter Locked In Place: Notes
- Remove the instrument panel cover below the steering column, then remove the steering column shrouds to gain access to the brake transmission shift interlock (BTSI) solenoid. The solenoid is part of the interlock cable assembly.
- Disconnect the wire connector from the rear of the BTSI solenoid.
- Insert the ignition key and turn it to the ON position.
- With the brakes applied, try moving the shifter out of the PARK position.
- If the lever now moves freely in and out of PARK, perform the Circuit Test below.
- If the shift lever still does not move from the PARK position, remove the BTSI solenoid from the shift lever assembly.
If the shift lever now moves freely in and out of the park position, the BTSI solenoid is faulty and the interlock cable must be replaced. If the shift lever still does not move from the park position, the problem is in the shift lever assembly or the ignition interlock cassette.
