I'm assuming your meaning the torque convertor lock solenoid... for that you'd have to seperate the motor from tranny and locate it on your stock toque convertor... or may need the whole convertor..

Where is module on brake peddle for shifting out of park on cadilac srx4 2007


There is no module on the brake pedal . There is a brake switch , do the brake lights work ? If the brake lights work switch is ok .
Automatic Transmission Shift Lock Control Description and Operation
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 solenoid (serviced as the automatic transmission shift lock actuator), as well as the body control module (BCM) and the engine control module (ECM). The shift lock solenoid is located within the floor shift control assembly with vehicles equipped with floor shift.
• The body control module (BCM) controls the voltage supply circuit of the shift lock control solenoid. The following conditions must be before the BCM will supply voltage to the shift lock control solenoid.
The BCM controls the voltage to the shift lock control solenoid through the shift lock control solenoid controlled voltage circuit. The following conditions must be met before the BCM will supply voltage to the shift lock solenoid:
• The ignition is in the ON position.
• The engine control module (ECM) sends an input via GMLAN serial data to the BCM indicating the transmission is in the PARK position.
• The BCM determines the brake pedal is applied according the brake pedal position.
Since the shift lock control solenoid is permanently grounded, the BCM supplies voltage to the automatic transmission shift lock control solenoid, mechanically unlocking the shift lever allowing the driver to move the shift lever out of the PARK position as the solenoid energizes. When the brake pedal is not applied, the BCM turns the control voltage output of the shift lock control solenoid OFF, de-energizing the shift lock control solenoid. The de-energized solenoid mechanically locks the shift lever in the PARK position.
During remote start operation, the BCM will de-energize the shift lock control circuit, locking the shift lever in the PARK position.

Your best bet ,have it towed to a qualified repair shop !

Holden cruze 2009 key stuck in the ignition won't go to off position , can't get it out of park .What is the problem ?


Is it shifter on the floor ?
Ignition Lock Cylinder Control Actuator
If the vehicle is equipped with a floor mounted console gear shifter, it has a ignition lock cylinder control actuator system in the steering column. The ignition lock cylinder control actuator's purpose is to prevent the ignition key from being turned to the OFF position when the transmission is in gear and the vehicle may still be moving. The column ignition lock system consists of a ignition lock cylinder control actuator , and a park position switch that is located in the A/T shift lock control switch. The ignition lock cylinder control actuator contains a pin that is spring loaded out to mechanically prevent the ignition key cylinder from being turned to the lock position when vehicle transmission is not in the Park position. If vehicle power is lost, and/or the transmission is not in the Park position the operator will not be able to turn the ignition key to the lock position and will not be able to remove the ignition key from the column.

GM had problems with these ! Has a TSB - technical service bulletin !

My 2003 GMC ENVOY won't shift out of 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.

How to replace a TCC solenoid on a 2001 dodge ram


The solenoid is inside the transmission.
Just because you have a P1740 that doesn't mean the TCC is assertive, have you done the testing with alive data scanner?

The factory doesn't serive the TCC solenoid seperatly, you need to buy the entire valve body, you may be able to buy it in the aftermarket not sure, talk to a local transmission rrepair shop, they may no this.

2 - WIRE HARNESS
3 - PARK ROD
4 - GOVERNOR PRESSURE SOLENOID
5 - GOVERNOR PRESSURE SENSOR
REMOVAL
The valve body can be removed for service without having to remove the transmission assembly.

The valve body can be disassembled for cleaning and inspection of the individual components.

The only replaceable valve body components are:

Manual lever.
Manual lever washer, seal, E-clip, and shaft seal.
Manual lever detent ball.
Throttle lever.
Fluid filter.
Pressure adjusting screw bracket.
Governor pressure solenoid.
Governor pressure sensor (includes transmission temperature thermistor).
Converter clutch/overdrive solenoid assembly and harness .
Governor housing gasket.
Solenoid case connector O-rings.
Shift transmission into NEUTRAL.
Raise vehicle.
Remove gearshift and throttle levers from shaft of valve body manual lever.
Disconnect wires at solenoid case connector (Transmission Case Connector).
Position drain pan under transmission oil pan.
Remove transmission oil pan and gasket.
Remove fluid filter from valve body.
Remove bolts attaching valve body to transmission case.
Lower valve body enough to remove accumulator piston and springs.
Work manual lever shaft and electrical connector out of transmission case.
Lower valve body, rotate valve body away from case, pull park rod out of sprag, and remove valve body.
INSTALLATION
Check condition of O-ring seals on valve body harness connector . Replace seals on connector body if cut or worn.
Check condition of manual lever shaft seal in transmission case. Replace seal if lip is cut or worn. Install new seal with 15/16 deep well socket (Manual Lever Shaft Seal).
Check condition of seals on accumulator piston (Accumulator Piston Components). Install new piston seals, if necessary.
Place valve body manual lever in low (1 position) so ball on park lock rod will be easier to install in sprag.
Lubricate shaft of manual lever with petroleum jelly. This will ease inserting shaft through seal in case.
Lubricate seal rings on valve body harness connector with petroleum jelly.
Position valve body in case and work end of park lock rod into and through pawl sprag. Turn propeller shaft to align sprag and park lock teeth if necessary. The rod will click as it enters pawl. Move rod to check engagement.
CAUTION: It is possible for the park rod to displace into a cavity just above the pawl sprag during installation. Make sure the rod is actually engaged in the pawl and has not displaced into this cavity.

Install accumulator springs and piston into case. Then swing valve body over piston and outer spring to hold it in place.
Align accumulator piston and outer spring, manual lever shaft and electrical connector in case.
Then seat valve body in case and install one or two bolts to hold valve body in place.
Tighten valve body bolts alternately and evenly to 11 N·m (100 in. lbs.) torque.
Install new fluid filter on valve body. Tighten filter screws to 4 N·m (35 in. lbs.) torque.
Install throttle and gearshift levers on valve body manual lever shaft.
Check and adjust front and rear bands if necessary.
Install the transmission range sensor
Connect solenoid case connector wires.
Install oil pan and new gasket. Tighten pan bolts to 13.6 N·m (125 in. lbs.) torque.
Lower vehicle and fill transmission with Mopar® ATF +4, Automatic Transmission fluid.
Check and adjust gearshift and throttle valve cables, if necessary.

• The ignition is in the ON position.
• The ECM sends an input via GMLAN serial data to the BCM indicating the transmission is in the PARK position.
• The BCM determines the brake pedal is applied according the brake pedal position.

The de-energized solenoid mechanically locks the shift lever in the PARK position.
During remote start operation, the BCM will de-energize the shift lock control circuit, locking the shift lever in the PARK position.
Circuit/System Description
The body control module (BCM) controls the shift lock solenoid by providing battery voltage to the shift lock control solenoid. The BCM utilizes a smart driver to control the voltage supplied to the shift lock solenoid. The smart driver monitors the voltage and current flow of the control circuit.
Diagnostic Aids
• Use a scan tool to verify there are no brake pedal position sensor and/or transmission internal mode switch (IMS) DTCs set that could cause the BCM not to provide battery voltage to the A/T shift lock solenoid.
• If the automatic transmission shift lock control circuit is shorted to battery positive voltage, the A/T shift lock solenoid will be inoperative. The vehicle will shift out of PARK without depressing the brake pedal.
Your best bet is have it towed to a repair shop !

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.
Shift Lever Does Not Move with Brake Pedal Depressed
DEFINITION: Transmission shift lever will not move out of the PARK position with the ignition ON and the brake pedal pressed.

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 !
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 park/neutral safety switch.

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.
