Hi, I'm Shaun. I will do my best to help you with your problem. From your description,l it sound like you may have one of two things going on. First, your brake light switch, located under the dash at the top of your brake pedal, may have gone bad. You can check this by simply checking your brake lights. If they come on when you push the pedal, this switch should be good. The brake pedal switch sends a signal to a small solenoid located under the console at the base of your shifter. If this part has gone bad, it will not release your shifter when the brake pedal is applied. These are the two main causes of this malfunction, as it's a fairly simple circuit and pretty easy to troubleshoot. The only downside is having to remove the console to get at the shifter, if you have a console shifter. If you need a more in depth walkthrough,l feel free to reply to this thread and I will contact you. Best of luck!

You may have an electrical or mechanical fault within the shift lock mechanism. have the brake switch and the shifter lock inspected for proper function. If there is power failure within this system, it will prevent the shift linkage from moving. Also the key lock cylinder may also cause this if it is worn or faulty!! Hopefully this helped!!

SOURCE: gear shift of f-150 is locked in park. The truck

Is the CHMSL ( Center High Mount Stop Lamp ) working ?
Is it a regular bulb, or did it get changed to a LED ?
If it is a functioning factory type bulb, the shift interlock solenoid is the cause.
Until you can fix the CHMSL or the shift interlock, you can turn the key to the run position ( do not start ), press and hold the brake pedal, shift into neutral, and then start the truck.
Your MY the shift interlock circuit and the brake lamp circuit are the same.
Usually the shift interlock stops working when the brake lamp fuse is blown, or if the bulbs are out ( truck does not see a load on the circuit ).
If LED tail lamps were installed without load resistors, the shift interlock circuit will not work ( looks like a burnt out brake lamp bulb )

Should be a switch further up the brake pedal that contacts when the brake pedal is pressed. Check this switch to see if defective or broke.

Where is location the automatic transmission shift lock relay in my s10 1998 2.2 2wd


Automatic Transmission Shift Lock Control Description
The brake transmission shift interlock (BTSI) system prevents the automatic transmission from being shifted out of PARK unless the brake pedal is depressed. When the brake pedal is depressed, the BTSI solenoid releases a lock pawl. This enables the shift linkage to move and the shift lever to operate.
When service operations are required, the BTSI system can be overridden.
On vehicles equipped with a column-mounted shift lever, override the BTSI system by performing the following steps:
  1. Turn the ignition switch to the OFF position.
  2. Remove battery voltage from the solenoid.
  3. Turn the ignition switch to the ON position.
For vehicles equipped with floor-mounted shift levers, an override lever is mounted on the right side of the assembly. The override lever can be accessed by removing the shift lever boot. Push the lever to the left in order to override the BTSI.
Which does your S-10 have column or floor shift ? No relay ,has a solenoid .
With Column Shift A/T
The brake transmission shift interlock (BTSI) system prevents the automatic transmission from being shifted out of the PARK position unless the following conditions are present:
?€¢
The brake pedal is depressed.


?€¢
The ignition switch is turned to the RUN or the START position.

When the ignition switch is in the RUN or the START position, the current flows from the B/U Lamp fuse located in the underhood bussed electrical center (UBEC) through CKT 839 (PNK) to the park/neutral position switch. The park/neutral position switch also feeds the backup lamps portion of the switch. With the transmission in the PARK position, the current flows to the BTSI fuse located in the underhood bussed electrical center (UBEC) through CKT 275 (LT GRN). The current then flows to the TCC/stoplamp switch through CKT 584 (LT GRN/BLK). The current continues to the BTSI solenoid through CKT 1135 (DK GRN/WHT). The ground path is provided through CKT 1850 (BLK) to G207. When the brake pedal is depressed, the normally closed contacts in the TCC/stoplamp switch open and the current flow is interrupted. When the current flow is interrupted, the BTSI solenoid de-energizes. The transmission may then shift to another gear. When the transmission shifts to another gear (except PARK), the contacts in the park/neutral position switch open. This condition stops the current flow to energize the solenoid when the brake pedal releases.

2002 buick century sticks in park positon sometimes


Nest time you can not get it out of park take a look at the brake lights. If the brake lights are not illuminating than you possibly have a bad brake switch. The solenoid that holds the shift lever in park is released when the brake pedal is depressed. If the brake switch is not working the gear shift will not move.

Gears won't change. Can anybody provide some useful advice. ?


Automatics have a gear shift safety solenoid that locks the gearshift/transmission in park unless the brake pedal is depressed. This is to prevent people from dropping into a gear from park and rolling into traffic or backing up over someone unexpectedly. When you press the brake pedal you should be able to hear a clicking sound coming from under the gear shift lever. If you dont hear the sound then the solenoid may need to be replaced. The other possibility is needing to replace the brake pedal position switch (usually attached to the pedal assembly or behind the brake pedal assembly) which tells the shifter solenoid to activate when the pedal is depressed.

Transmission wont shift out of park


Try checking the brake light sending unit. Are your brake lights even working. Many newer vehincles will not shift out of park unless the brake pedal is depressed. However, a faulty sendind unit located on the pedal itself can keep you from moving anywhere. Just check to see if your brake lights are working to know if the sending unit is working.

Car wont move out of park


There is an interlock that requires the brake pedal to be depressed in order to shift the car into gear. So...first question (I have to ask!): Did you make sure to press the brake while trying to shift out of park? If so, theres a good chance that the brake switch is bad.
