Sounds like you probably bent the "detent" in the transmission. You'd need to drop the trans pan and replace the linkage pertaining to this.

Sounds like a bad ingition switch. When you turn the key it pushes a rod that goes down the steering colum. The switch is located there. It's a pretty simple fix.

Does the transmission work in all 4 gears? I've seen bad ignition switches cause this. Not the ignition lock cylinder, the electrical switch.

Soounds like the shop that did the work did not install the shift cable back onto the transmission fullky and it popped off. Look under the truck, drivers side, and you may see a cable dangling. If so that needs to be reconnected to the post on the transmission shift selector on the transmission.it should pop on with a solid push.

05 Trailblazer transmission says neutral but gear shiftier is locked in park.


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 the PARK position. The system consists of the following components:
• The automatic transmission shift lock control solenoid
• The automatic transmission shift lock control switch
With the ignition in the ON position, voltage is supplied to automatic transmission shift lock control switch. Voltage flows through the normally closed contacts of the automatic transmission shift lock control switch to the automatic transmission shift lock control solenoid. The automatic transmission shift lock control solenoid is permanently grounded. This energizes the automatic transmission shift lock control solenoid causing the transmission shift lever to be physically locked in the PARK position. When the brake pedal is pressed 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 be move out of the PARK position.

Circuit Description
The transmission range (TR) switch is part of the park/neutral position (PNP) and back-up lamp switch assembly, which is externally mounted on the transmission manual shaft. The TR switch contains four internal switches that indicate the transmission gear range selector lever position. The powertrain control module (PCM) supplies ignition voltage to each switch circuit. As the gear range selector lever is moved, the state of each switch may change, causing the circuit to open or close. An open circuit or switch indicates a high voltage signal. A closed circuit or switch indicates a low voltage signal. The PCM detects the selected gear range by deciphering the combination of the voltage signals. The PCM compares the actual voltage combination of the switch signals to a TR switch combination chart stored in memory.

These are all electronically controlled , yur best bet would be to take your vehicle to the dealer .

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.

Stuck in park will not shift


Automatic Transmission Shift Lock Control System
The automatic transmission shift lock control is a safety device that prevents an inadvertent shift out of PARK when the ignition is ON. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
?€¢
The automatic transmission shift lock control solenoid.


?€¢
The automatic transmission shift lock control switch.


?€¢
The park/neutral position switch.

With the ignition in the ON position, battery positive voltage is supplied to the park/neutral position switch. When the transmission is in the PARK position the contacts in the park/neutral position switch are closed. This allows current to flow through the switch 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 automatic transmission shift lock control solenoid is permanently grounded. This energizes the automatic transmission shift lock control solenoid, locking the shift linkage in the PARK position. When the driver presses the brake pedal the contacts in the automatic transmission shift lock control switch open, causing the automatic transmission shift lock control solenoid to release. This allows the shift lever to move from the PARK position.
Park Lock Solenoid
The park lock solenoid is a safety device that prevents an inadvertent shift out of PARK when the key is in the OFF position. The key must be in the RUN position to release the park lock solenoid. The system consists of the park lock solenoid. With the ignition in the ON position, voltage is supplied to the park lock solenoid. The park lock solenoid energizes through a permanent ground unlocking the shift lever. With the ignition in the OFF or ACCY position the park lock solenoid de-energizes and locks the shift lever in the park position.

1995 Ford Escort Wagon Automatic, Won't shift


Hi there,

Most modern automatic cars require the driver to depress the brake pedal first, to allow releasing the gear out of Park.

Some automatic transmissions also provide an 'overide' switch near the gear lever, to allow manual release of the gear lever.

If neither of the above resolve this, then you will need to check the operation of your brake switch, mounted on the brake pedal.

My 2007 chrysler pacifica wont shift out of park.


SHIFTER LOCKED IN PLACE

  1. Remove the instrument panel cover below the steering column, then remove the steering column shrouds to gain access to the brake transmission shift interlock (BTSI) solenoid. The solenoid is part of the interlock cable assembly.
  2. Disconnect the wire connector from the rear of the BTSI solenoid.
  3. Insert the ignition key and turn it to the ON position.
  4. With the brakes applied, try moving the shifter out of the PARK position.
    • If the lever now moves freely in and out of PARK, perform the Circuit Test below.
    • If the shift lever still does not move from the PARK position, remove the BTSI solenoid from the shift lever assembly. If the shift lever now moves freely in and out of the park position, the BTSI solenoid is faulty and the interlock cable must be replaced. If the shift lever still does not move from the park position, the problem is in the shift lever assembly or the ignition interlock cassette
