Having problems with shift button on 91 Lexus LS400 it gets stuck on Park. I press on break no response.

If your 2007 Impala is stuck in park and the gear override silver button doesn't work, there may be a few potential problems that are causing the problem. Here are some common causes and troubleshooting solutions you can try: Brake light switch: The most common cause of this problem is a faulty brake light switch. The brake light switch is responsible for sending a signal to the shift interlock solenoid to release the shifter when the brake pedal is depressed and can prevent the shifter from releasing if the switch does not operate properly. Make sure your brake lights work by pressing on the brake pedal. If they don't work, it's probably a brake light switch issue that needs to be replaced. Shift Interlock Solenoid: The shift interlock solenoid is a mechanism that prevents the shifter from moving without pressing the brake pedal If the solenoid is faulty or a blown fuse can cause the shifter to go into park. Check the fuse connected to the shift interlock system and replace if necessary. If the fuse is good, the solenoid may need to be replaced. Shift Cable: The shift cable connects the shifter to the transmission and allows you to change gears. Damaged, loose, or misaligned cables can prevent the shifter from leaving the parking space. Inspect the shift cable for any obvious issues and make sure it is securely attached to the shifter and transmission. Shift lock control module: Some vehicles have a shift lock control module that ensures proper operation of the shift interlock system. Malfunction of this module can cause the problem. It may be necessary to use a diagnostic scan tool to check for any error codes associated with the module. Ignition switch: Faulty ignition under certain conditions

I believe that they are interchangeable up until 1997.

Sounds like a major fuse blown.
Any wiring disconnected or stripped near the pump ?
Have you checked the major fuses around the battery and underhood fuse box ?

It
can be issue with gears or problem with transmission and needs to be rebuilt.
Also get the tranny fluid checked. If it\'s low, then such problems
occurs.

this is a computer problem. 91-96 lexus ls400 are known for having their computers go out on them. I would have never believed it but my ls400 did the same thing. I sent the computer to Auto Computer Exchange in Davie FL. They reprogramed it for $310 sent it back to me in a day. It fixed the car. I have had no problems out of the car. I now work on ls400 on the side to fix the same problem for other people.

sounds like you have bent something underneath or broke a support bracket
