Transmission will not shift out of park. I pushed brake and the shifter will not move from park with the button on side of shifter pushed in.

Could be the interlock brake switch . don't guess an just replace parts . You don't know how to test , take it to someone who can .

Not to worry friend, when my machine go sick i avoided going to mechanic looking for DIY_Repair when I found this website https://big-manuals.com/ and this book helped me repair it within an hour, all by myself!!!
From wiring diagrams, schematic illustrations, spark plugs info, parts info, chassis number, valve time settings, step wise instructions, torque specs, error/fault codes, engine info, to every single minute parts, you get everything in there you can't imagine how detailed it is

Shift interlock system problem . Not the cable . Your vehicle has a safety system that won't allow the gear selector to be moved from park without the brake pedal pushed . Lock solenoid keeps gear selector from moving . Trying to force it will break something . Do you know how to test electrical circuits with a volt meter ? Here is a web site for free wiring diagrams http://www.bbbind.com/free_tsb.html
Enter the vehicle info. Year , make , model and engine size. Under system click on transmission / transaxle , then under subsystem click on shift interlock . Click the search button then the blue link. Park neutral switch , brake switch and the shift interlock solenoid , check electrical circuits .

Rock the car back and forth to remove parking pin from park .

Shift - interlock system problem .
Automatic Transmission Shift Lock Control System
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of PARK position. The system consists of the following components:
• The automatic transmission shift lock control solenoid
• The automatic transmission park lock solenoid
• The automatic transmission shift lock control switch
• The transmission range switch
With the ignition in the ON position, battery voltage is supplied to the automatic transmission shift lock control switch. The circuit continues through the normally-closed switch to the automatic transmission shift lock control solenoid. The transmission range switch provides a path to ground for the automatic transmission shift lock control solenoid in the PARK position. With the automatic transmission shift lock control solenoid energized the shift lever is mechanically locked in the PARK position. When the driver presses the brake pedal, the contacts in the automatic transmission shift lock control switch open, de-energizing the automatic transmission shift lock control solenoid. This allows the shift lever to move from the PARK position. When the shift lever is out of the PARK position the controlled ground contacts in the transmission range switch open. This prevents the automatic transmission shift lock solenoid from energizing when the vehicle is out of the PARK position.

The 1st thing you need to do is check the brake lights, if they are not wiorking the park lock solenoid doesn't get power and the park lock remains engaged.

2002 chevy trailblazer on neutral mode, trailblazer can be pushed easily,but shifter is stuck on park. vehicle will start.the push button on shifter will not engage

Hi there,

There are multiple things that must all happen in order for the shifter to move from park.

1. Make sure the key ignition switch is in the "Run" position (the position just before the "start" position).

2. Brake pedal is depressed (usually pushed in a couple of inches or more at least to release the button on the shifter).

3. Push in the button on the shifter and pull back (you may need to push the shifter slightly forward or back a little for the button to move freely).

If the button on the shifter still doesn't push in freely, there is a problem with the mechanical lock-out linkage or electronic switch that releases the button lock. Check under the dash area along the brake pedal arm for anything that doesn't look correct.

4. If the car is on an incline/slope/hill, it will put a lot of pressure on the parking pin in the transmission. Usually a strong tug or pull on the shifter will pull it out while you're pushing on the brake pedal to prevent rolling when it releases. Make sure to set the parking/emergency brake first to prevent this next time .

Good Luck!!

Thanks

cheak the brake pedel swich it work a swich in the gear seleter

You seem to have two (2) separate problems one may be a BAD brake light switch this switch is mounted at the top of BRAKE pedal and control the locking mechanism on gear shifter(safety component-for example if a kid is sitting in seat with vehicle running he/she will NOT be able to put vehicle in gear without stepping on brake). The other problem is a BAD shifter cable-this cable moves the selector in the transmission when you move shift knob. Good luck and thanks for using FIX YA
