Stuck in Park. Not the palstics parts!!!

Okay. My car 2003 S430 was stuck in park and had it towed to my home knowing the broken plastic part issue. I did tear down and got to the gear box. Plastic part in question is NOT broken, but the gear still does not engage. What else could it be? Is there a fuse or relay to look at? HELP!!

Module bad? or your tranny shot. Park is a mechanical lock. No fuses , no electronics. If you can move your lever back, it will be out of park. otherwise the connection on the bottom of your shifter came off, this goes from your shifter to your gear box. check out pic..

I did look at the gear box. Black plastic parts is not broken, but there was a metal piece that looks like enages or dis engages the shifter lever inside the gear box. I did manually moved to shift. Isn't there a solenoid that actuates that metal lever to engage or disengage? I did pull in the connection into the car and disconnected to take the gear box off. I did reattach back securely.

Where is this module you are talking about?

THat metal peice connect to the soleniod and the cable that I show in the second pic. This is only to inhibit the key removal. Like I said if you cna move your lever back, then you car should be out of park. If it doesn't drive then you have a tranny issue or an issue with your module. When you move the lever you car should be able to roll no? If it does not ( which doesn;t make any sense,) you have something broke in your tranny as well.
Like I said park is a mechanical engagement.. If you can move your shifter, which in turn moved the big lever shown in the first pic, then you can get you car out of park. Are you sure your E-brake is released?

When I took the gear box off and manually moved by moving the metal piece.
When I put all back together and tried to move, it is still stuck and won't move.
E-brake is released and I have not had any tranny issue so far with new fluid and filter.
I might have to take all apart again and remove the gear box..... What is Fuse 37 for transmission control??

Now I'm confused by what you are saying..so your shifter is locked? The peice you said you removed is the peice in the pic from the bottom? IF that's the case, yes there is a solenoid that actuates the plastic peice. it is activated by your brake pedal switch.. maybe thats the issue.. check the switch on your brake pedal. you should hear the solenoid click on the shifter when you depress the brake pedal with the ignition in position 1. this is the solenoid unlocking the plastic peice. if there is no click, check the brake pedal switch.

Just want to add that the black plastic piece in the shifter usually has a hairline crack on one side of it not visible on inspection but you will see better once remove from the shifter assy. So check that again. And I agree that you should hear audible click in the shifter with key on and stepping on brake. If you hear the click then problem is def the black plastic lever inside

If it is a brake switch, where is this switch located? I checked the brake pedal and could not find it.

Plastic part out but still very stiff to shift from Park

I got the plastic part out and still, it is very stiff to shift out of Park. What is this little thing with spring clip? WHat could still cause the resistance to shift from Park?

Tha peice is for the lever that keeps the key in the ignition when you are not in park. Not related to your issue. If you have removed the entire plasic peice then you should be good. if not, well, this is why its still hard.

I did remove the plastic piece completely. Maybe I might have damaged something while I was pounding that thing with mallet and yanking to release.... Or could it be shifter cable being stuck underneath?....
