My guess is the trans won't shift because of no power. There is a safety switch that is activated by the brake lights...no power means no lights and no lights means no shifting. Solve the power issue and you should have the trans working again.

For power it's time to get a probe and start at square 1. Battery? Have you tested it? Cables solid and CLEAN? These get overlooked a lot. Electrical is a hard one to solve over the net. But they are not hard to solve...just can be time consuming.

My 2003 Oldsmobile altero gets stuck and i have to jiggle the shifter or leave it set for a min befor if will go from park to reverse ect.. Just got the car yesterday

Your problem is more then likely with the Automatic Transmission Shift Lock Control .This is a safety thing . Has a switch , wiring and a electrical solenoid .
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:
ā€¢ The automatic transmission shift lock control solenoid
ā€¢ The automatic transmission shift lock control switch
ā€¢ The park/neutral position switch

Sorry to here your having a problem with it already .
There are diagnostic step to find the problem , involves using a DVOM - digital volt ohm meter an using a wiring diagram to locate test points in the circuit . Plus you will need to take parts of your vehicle apart to get to those test points . The most likely part to fail is the park neutral safety switch . The contacts wear inside after hundreds of times of moving the shifter . But without testing this is just a guess .

With the ignition in the ON position, battery positive voltage is supplied to the park/neutral position switch. With the transmission 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, mechanically 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, de-energizing the automatic transmission shift lock control solenoid. This allows the shift lever to move from the PARK position.

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:
?ā‚¬Ā¢
The brake pedal is depressed.


?ā‚¬Ā¢
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.

Abs light on wont shift out of park

Hi Judy , what kind of vehicle do you have ? Year an model ? ABS light has nothing to do with it not coming out of park . Problem with automatic transmission shift lock control ! Probably !

With the ignition in the ON position, battery positive 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 park/neutral safety switch provides a path to ground for the automatic transmission shift lock control solenoid in the PARK position. This energizes the automatic transmission shift lock control solenoid, mechanically 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 de-energize. This allows the shift lever to move from the PARK position. When the shift lever is out of the PARK position the contacts in the neutral safety switch open and the automatic transmission shift lock control solenoid is de-energized.

I have a 2006 mitsubishi galant es. I was recently in a rear end collision. The following day my brake lights went out. A couple hours later while reversing out of a parking spot, I went to put my car in...

here is what the code means.
http://engine-codes.com/p0705_mitsubishi.html

P0705 Mitsubishi Description The park/neutral position (PNP) switch includes a transmission range switch. The transmission range switch detects the selector lever position when the shift lever is in the N or P shift position and sends a signal to the Transmission Control Module (TCM).


When is the code detected? The transmission range switch detects the selector lever position and sends a signal to the TCM.

No back up lights. I need to know where the sensor is located at the transmission.

Look for the selector cable on the top or front of the transmission. The switch is the one the shift select rod comes though that has a lever on it and the cable is connected to the lever. This same switch also lets the car start in park or neutral. this is not as likly as the fuse being blown or the bulbs being bad or the light sockets the bulbs go in being bad too and there's the reason for the fuse to be blown.

Can a 1998 4x4 S-10 blazer be dinghy towed?

Yes it can, just place your Transfer Case in Neutral position.
Shifting into NEUTRAL
To shift the transfer case to NEUTRAL do the following:

Make sure the vehicle is parked so that it will not roll.
Set the parking brake.
Start the vehicle or turn the ignition to RUN.
Connect the vehicle to the towing vehicle.
Put the transmission in NEUTRAL (N).
Shift the transfer case to 2HI.
Simultaneously press and hold the 2HI and 4LO buttons for 10 seconds. The red NEUTRAL light will come on when the transfer case shift to NEUTRAL is complete.
Shift the transmission to REVERSE (R) for one second, then shift the transmission to DRIVE (D) for one second, or FIRST (1) for vehicles equipped with a manual transmission.
Turn the ignition to LOCK.
Place the transmission shift lever in PARK (P), or FIRST (1) for vehicles with a manual transmission.
Release the parking brake prior to towing.

Shifting Out of NEUTRAL
To shift out of NEUTRAL:

Set the parking brake and apply the regular brake pedal.
Shift the transmission to NEUTRAL (N) and turn the ignition to RUN with the engine off.
Press the button for the desired transfer case shift position (2HI, 4HI, AUTO 4WD or 4LO).
After the transfer case has shifted out of NEUTRAL the red light will go out.
Release the parking brake.
You may start the engine and shift the transmission to the desired position.
Excessively shifting the transfer case into or out of the different modes may cause the transfer case to enter the shift protection mode. This will protect the transfer case from possible damage and will only allow the transfer case to respond to one shift per 10 seconds. The transfer case may stay in this mode for up to three minutes.

NEUTRAL: Shift the vehicle's transfer case to NEUTRAL only when towing your vehicle.
Good luck and hope this answers your question.
