When I push down on the brake pedal, the gear shift remains locked. Unfortunately, the lock release button on the console is broken. By jiggling the gear shift, I was able to unlock the transmission but it no longer works. How do I get the lock to release.

All models are equipped with a shift-lock system. System locks gear selector in Park unless brake pedal is pushed down. Shift-lock actuator uses an integral relay to release a solenoid (mounted on gear selector assembly).

On 1994 Miata, a key interlock solenoid and control unit prevents ignition key from being removed unless gear selector is in Park. With ignition key removed, gear selector locks in Park.

On all other models, a mechanical control cable prevents ignition key from being removed unless gear selector is in Park.

FUNCTION CHECK
1.With ignition key removed, ensure gear selector cannot be moved from Park. Insert key in ignition switch.

2.Turn ignition on. Ensure gear selector can only be moved with brake pedal pressed down. Move gear selector to Reverse.

3.Ensure ignition key cannot be removed. Move gear selector to Park. Ensure it is now possible to remove ignition key.

4.If shift-lock system does not operate as described, check gear selector, shift-lock solenoid and control cable or key interlock solenoid and control unit.

5.On B2200, B2600 and 1993 Miata, slide back override button. On MPV, place gear selector in Park. Depress and hold emergency override link. See Fig. 2 .

6.On all models, if gear selector cannot be moved out of Park, adjust or replace shift-lock actuator. To adjust shift-lock actuator, see appropriate TRANSMISSION SERVICING article in TRANSMISSION SERVICING section.
