Won't switch out of park

Hi there,

Some automatic vehicles rely on the brake switch (mounted on brake pedal) to be activated by depressing brake pedal. This signal then operates a relay and switch, to release the gear lever.

Firstly, I would check the brake pedal switch (are your brake lights working?).

If brake switch is confirmed OK, then inspect the relay (and related circuit components) of the gear release switch.

Brake Switch somehow got out of adjustment
with the brake booster install.

Now you don't have that signal to the computer
to release the shift solenoid,sloppy work

engine size, etc., I can only make educated guesses, but here goes: You stated "My car will drive, but very slow hardly moving". My first suspicion is that you don't have a transmission problem, but the car is in what Chrysler calls the 'limp-home mode'. This occurs when the computer 'sees' a problem with an engine function or sensor that is serious, but not so bad that the car won't run at all. Limp-home mode allows your car to only operate in second gear so that you won't damage it further by driving normally, but won't leave you stranded either. Is your 'check engine' or 'service engine' light on? If not, check to see that it actually works by turning the key 'on', but not starting the car. All the dash lights should be lit for about 3-5 seconds. No matter what, you need to check your transmission fluid level (on a Crysler, should be checked with the engine running and in gear, NOT park or nuetral). Safety first, make sure someone is holding the brake on - please don't ever trust a 'parking brake' for this. If the fluid level is OK and there's no 'check engine' light you need
to visit a competent transmission shop. Probabably a worn front pump, torque converter, or a hung spool valve in the valve body, none of which is generally fixable at home. If you do have a 'check engine' light on, see a regular mechanic first as there is a mechanical problem probably not related to the transmission. Good Luck!

Do the brake light work? No brake lights and it won't shift out of park. Check your fuses and check for loose wires. Check your brake light switch. If that has failed, you won't be able to get out of park. The other one if the shift lock solenoid which is in the shifter assembly. The brake shift interlock switch prevents the car being shifted from park unless the brake pedal is depressed. Try to apply power/ground to the proper wires & see if it will activate.. If it does, then the problem is between the brake light switch & that solenoid. Could be the wires or the switch.Make sure the shifter cable is still held down in place at the shifter assembly & under the hood. It is the interlock switch that you hear/feel clicking.It is for the prior generation but may still apply.

Good Luck and hopefully you soon will be on the road again...;-)

I had this issue in the past. All I did was to replace the brake switch. This part is located behind the brake pedal. Btw, if you this run into this issue again in the future, you can always push this switch with your finger and it's located on top of your steering wheel enclosure, this will disengage the shifter.there is a small rectangle shape cover that you need to remove first.

This might work for you guy's replace the brake light switch
Easy step by step tutorial watch the video. im sure it will help.

you should hear a click from the solenoid when you apply the brakes. If your brake lights don't work, your shift lock release won't either. There is a bypass method for emergencies in your owner manual. Check fuse for brake lights. And switch on brake pedal

Must be the release mechanism tied to the brake pedal is loose or bad. don-ohio

If the engine starts, but wont shift out of park, you should check that your brake lights are working. The interlock solenoid is powered by the brake light switch, if the fuse is blown or if the brake light switch is bad, the car wont shift out of park...I hope this helps.

Check to see if your brake lights are working. If not, you have a blown fuse for the brake lights or a bad brake light switch on the brake pedal arm bracket.
When you turn the key to ON, a solenoid energizess and lock the sihft interlock. When you step on the brake to shift out of park, It de-energizes the relay so you can move the sift lever. You should hear a click noise with they key in ON position and you step on the brake pedal. TRy this witohout starting the engine & listen.
The bypass emergency procedure is in your owner manual under sift interlock in the index.
But, usually you turn the key to OFF (first click) and then step on the brake & shift out of park. Then start car in neutral and drive away.
It works because you did not energize the shift lock solenoid, by not turning key to ON.

report results and please rate, thanks.

Also, check the wire going to the brake switch under the dash. It may have just come off.
