Question about 2005 Chevrolet Uplander

1 Answer

I have a Chevy 2005 uplander. When I try to shift out of park it stays locked up. In the manual it says that there is a torque lock and my mechanic says that it should release when the brake is depressed. Sometimes it does but 50 to 60% of the time it stays locked and it takes several minutes of working with it to get it to release. Do you think that the switch in the brake pedal needs to be replaced, if there might be another problem, can this switch be bypassed, and what the repair cost might be.

Hello, sounds like you need to change the switch, sounds like the switch is going bad, because it is taking time to let you put your car in gear, soon as you put foot on brake the switch should activate, almost immediatley, then put the car in gear, i had a nissian , that did this, went to junkyard, bought used one for 20.00. new one was about 50.00. still working today.

Can't shift my Chevrolet Uplander out of park.


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 body control module (BCM)


?€¢
The powertrain control module (PCM) or the transmission control module (TCM).

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 PCM / TCM sends an input to the BCM indicating the transmission is in the PARK position.


?€¢
The BCM determines the brake pedal is not 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 locking the shift lever in the PARK position as the solenoid energizes. When the brake pedal is 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 releases the mechanical lock allowing the driver to move the shift lever out of the PARK position. When the transmission is out of the PARK position, the shift lock control solenoid remains de-energized.
The body control module (BCM) controls the A/T shift lock control solenoid by providing battery voltage to the A/T shift lock control solenoid. The BCM utilizes a smart driver to control the voltage supplied to the A/T shift lock control solenoid. The smart driver monitors the voltage and current flow of the control circuit.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC B2705 Gearshift Unlock Circuit
You could have a bad brake light switch , automatic transmission shift lock control solenoid.
the BCM or wiring problem
Install a scan tool. Turn ON the ignition, with the engine OFF. Press and release the brake pedal several times while observing the BTSI solenoid parameter in the body control module (BCM) output data list

2008 chevy uplander seat belt wont retract how do i fix it


Please check if your seat belt has "Retractors" or "Automatic Retractor".

Follow these steps to determine if you have a retractor system that will hold car seat securely or your seat belt won't retract as should be:

A. Pull belt all the way out.

b. Allow belt to retract about 6 inches (15 cm).

c. Pull out on belt again.

If belt is locked and you cannot pull the belt out any further, you have an Automatic Locking;

If you pull the belt again all the way out and won't return to normal operation, then the mechanism is damaged, but try first the "retractor" lock to be sure. By Federal Law, nobody will sale a seat belt in a junk yard, try the dealer or order thru the dealer the whole seat belt or the mechanism. I hope that is just a matter of the automatic retractor; you can see this information in your car's manual. Try and we will see.

Liftgate on 2005 uplander won't open


The locking mechanism on the rear lift gate for the Chevy Uplander has some plastic and rubber-coated parts that can get jammed. If you can pull back the panel from the inside top near the glass, you can reach down and try to spray some silicone lubricant into the lock. This could help get those parts unstuck so they spring back when you pull on the handle latch from the outside. Once you get the rear hatch open, I recommend taking out the locking mechanism and thoroughly lubricating it. Your rear lift gate will start to release very easily from then on.

Chevy uplander rear liftgate will not unlock


The tailgate on my 2008 Chevy Uplander refused to open. The unlock fuse was fine. The handle pull worked fine. I could even hear the little motor that unlocks the tailgate whirr when I pushed the unlock button. But the gate would not release. Turns out the problem was the lock mechanism was jammed because it had dirt in it and not enough grease. From the inside, I pulled the lift gate panel out at the window so I could look down and see the lock mechanism at the bottom of the lift gate. I reached down and prodded it with my screwdriver until I noticed that parts of the mechanism weren't sliding back and forth like they should. I sprayed it with a silicone lubricant until the parts started working again. Finally, the lock unlatched and I could open the rear hatch. I could then remove the entire plastic panel and remove the lock mechanism. I found that the mechanism has lots of rubber and plastic parts which get chewed up and start to jam if not properly lubricated. I cleaned out the dirt with my silicone spray and thoroughly lubricated all the moving parts. The latch now lets go of the post very easily, and the lift gate no longer gets stuck.

Power train control module. Reprogram with the correct software and calibration. If that doesn;t work, then PCM must be replaced and programed with correct software. Bring to a mechanic.

2005 chevy uplander having diffculty putting into Drive. sometimes have to wait 5 min some type of sensor most be going bad


check the brake lights and see if they work when this problem happens, U may have a problem with the Park lock system, this locks the gear shift out until the brake pedal is pushed, then a electric solenoid releases a pin and allows u to come out of park, if the brake lights check ok then the solenoid may be sticking at times. Does this sound more like your problem?
