SOURCE: 2006 Chevy Aveo, can't shift car out of park

You need to replace your BTSI (brake transaxle shift interlock) solenoid. I have replaced MANY and it is the problem 99% of the time. The only other thing it could be is your BTSI fuse so check it first. All you have to do is remove the shifter assembly and install a new BTSI solenoid (couple of screws and two connector terminals) and you will be driving in no time. Hope this helps!!

SOURCE: had transmission rebuilt in my s10 blazer now it

Transmission does not shift automatically, only manually. Swap in a known-good PCM, check wiring, check other sensors such as VSS and TPS.

3rd gear starts, can manually shift through all gears. When car has been turned off for a bit, then back on it will run normally.: VSS drop off w/ Hi-stall converter. The rpms are too high, but VSS is showing no movement. Happens after a tire burning take-off. Doesn't store a code, will not throw a CEL (I've heard that it will store a code if it happens 3 or more times). Cure: Reprogram PCM for VSS drop off -- PCMforLess knows about it.

Note that many problems that show up as transmission issues are actually PCM or electrical, and may be external to the transmission. Try a different PCM, and check for chafing where the cables come out of the PCM or the transmission on the passenger side.

Good luck and thank you for using Fixya.

JUST PURCHASE 2000 MUSTANG 2 DAYS AGO. NOW WILL NOT SHIFT OUT PARK. I ASK A PERSON THEIR ..HE SAID TURN THE KEY HALF WAY & THE SHIFTER WENT INTO NERUTAL & CAR STARTED..WHAT COULD BE THE PROBLEM?


Brake switch, shift interlock solenoid or bad transmission range selector. Shift interlock won't let you shift out of park unless your foot is on the brake. So brake pedal starts the cycle. Next, the vehicle has to be in either park or neutral. So power flows from the brake switch through the transmission range selector which then sends power to the shift interlock solenoid which moves a pin out of the way, allowing you to shift out of park.

2010 merc gm shift lever stuck in park car will start steering wheel turns


You have a shift interlock problem . What kind of vehicle ? a mercury what ?
Shift Interlock System
The shift interlock system prevents shifting from PARK unless the brake pedal is depressed. The shift interlock system consists of a shift lock actuator mounted on the selector lever. If the ignition switch is in the RUN position, the shift lock actuator is disabled when the brake pedal is depressed.
If the selector lever will not move out of PARK with the key in the ON position and the brake pedal depressed, it will need to be unlocked manually.
Do the brake lights work ?
Visually inspect for obvious signs of mechanical and electrical damage; refer to the following chart:

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.

My car won't start and is stuck in park.


Will the starter motor crank? Do you have a shift interlock bypass button? If there is one and you have a console shifter, it should be close to the shifter, with foot on the brake, push the button down and shift into neutral, then see if it will start.
I can think of two possibilities, the shift interlock system, won't let you shift it w/o your foot on the brake and or the neutral switch/transmission range sensor, won't let you crank it unless the tranny is in park or neutral.
Don't replace anything unless your testing points in that direction.

Fuse for brake lights keeps blowing out, shifter won't go into gear


Your vehicle has a safety system that won't let you take it out of park unless you have the brake pedal pressed ! Your brake switch could be shorted inside causing fuse to blow !
Shift Interlock System A brake/shifter interlock mechanism prevents shifting the transmission out of the PARK position unless the brake pedal (2455) is applied. The system consists of the following components:
  • an actuator activated by the key interlock assembly and brake pedal pressed input.
  • necessary wiring.
The system operates as follows:
  • The actuator is energized when the ignition switch is turned to RUN, locking the transmission range selector lever in the PARK position. When the brake pedal is applied and the stoplight switch (13480) is activated, the shift lock actuator is deactivated.
  • The transmission range selector lever can be moved out of the PARK position.
The ignition/shifter interlock cable (3F719) locks the transmission range selector lever in the PARK position when the ignition switch is in the LOCK position. It also requires the selector lever to be in the PARK position to turn the ignition switch to the LOCK position.

Why won't 2003 pontiac grand prix. shifter come out of 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.

I have a 1999 Ford Escort and this morning could not get the silly thing to shift out of park. The release button on the shifter will not push in to move the shifter into drive or any other gear


These cars have a shift interlock switch that prevents the car from being shifted out of park if you don't depress the brake. If your brake lights work, then the switch it good. It isn't uncommon that the interlock solenoid fails. The solenoid moves the lock release when you depress the brake. If you look on the side of the console you can see a notch cut out. You can put a screwdriver in there to push the interlock and shift it from park. Of course, you don't want to do this all the time so you either need to replace the interlock solenoid (last I checked they were about $150) or just defeat the solenoid with a zip tie. The only problem with the zip tie is that you don't have to depress the brake to shift it from park and it can be shifted from park even if the key is not in it. Your owners manual will have better detail and pictures of the interlock and where to put the screwdriver to manually shift it from park.

Wont shift from park to drive its stuck


THE MOST COMMON PROBLEM IS THE BRAKE LAMP SWITCH. GET SOMEONE TO CHECK TO SEE IF WHEN YOUR HITTING THE BRAKE THE LIGHTS ARE COMING ON. IF NOT THE SWITCH IS BAD OR THE WIRE GOING TO IS BROKEN. IF THE LIGHTS ARE WORKING THE SHIFT INTERLOCK IN THE SHIFTER MAY BE DEFECTIVE

2005 Dodge Magnum STX is stuck in park. Brake lights work, I can feel shift knob loosen but not disengage from park. Do you think it might be part of "the cup plug that retains the park pawl anchor shaft"...


The BTSI (Brake Transmission Shift Interlock) has a small spring retainer on the park safety. A small plastic tab breaks & releases the spring. This requires the shifter to be disassembled in order to be repaired (unless yours is under warranty).

Repaired mine Sunday May 1st and can provide detailed instructions if desired.

If you are lucky, your brake interlock is the only problem. There is a bypass switch located beside the gear selector. Remove the small "cubby" bin located next to the gear shift by simply lifting up to remove. You will note a small access port and a pink button contained therein. Press the pink button to override the brake interlock.

If you still cannot shift into park, then the shifter must be removed for the spring repair. Even if yours is still under warranty, you will get another shifter that will eventually fail due to poor engineering.

Please let me know if you would like my assistance.
