Is it possible to put a 2022 Sierra in neutral with the car off?

My 2022 Sierra Denali had a fuel pump issue and randomly shut off while I was in line on the road with a bunch of other cars. We could not get it in neutral and the tow truck that eventually came had to drag it onto the bed which is obviously not great. I guess this is for safety purposes, but is there really no way to override this feature to move a stalled car out of a dangerous situation?  I have to regularly park in a garage for work and if my car won’t start in there it would be too low for a tow truck to get in.

In the owner's manual, transmission use section: look for "car wash mode". Several options, but for a tow:

 

To place the vehicle in N (Neutral) with the engine off and the vehicle unoccupied:

 

1. Drive to the entrance of the car wash.

2. Apply the brake pedal.

3. Open the door.

4. Shift to N (Neutral).

5. Turn off the engine and release the brake pedal.

6. The indicator should continue to show N. If it does not, repeat Steps 2–5.

7. Exit the vehicle and close the door. The vehicle is now ready for the car wash.

8. The vehicle may automatically shift to P (Park) upon re-entry.

 

Should work with the truck on (long press of the start/stop), the engine doesn't need to be running.

Can I assume you have the updated 2022.5 with the shift by wire console shifter?

 

If so, no, the engine must be running to exit park position.  Transmission requires hydraulic pressure (engine running) to relieve the park pawl.

 

The only bypass is a special tool that GM dealers would have for moving a dead vehicle around the lot.  Its a cable that is installed which allows a temporary override of the park pawl.

 

If you had the column shift, those can be shifted with the engine off.  


Not sure why GM didn't add one of those pull cables like Jeep and other vehicles have.

@newdude will the two speed transfer case shift to neutral with the engine off?

 

 

Transmission has to be in neutral to shift the transfer case into neutral first, so engine has to be running on a console shift truck.  It doesn't specify for column shift but I assume they wrote it this way to cover both.

I think its hilarious GM thinks this can be pulled off easily just to go through a car wash.

 

1. Drive to the entrance of the car wash.

2. Apply the brake pedal.

3. Open the door.

4. Shift to N (Neutral).

5. Turn off the engine and release the brake pedal.

6. The indicator should continue to show N. If it does not, repeat Steps 2–5.

7. Exit the vehicle and close the door. The vehicle is now ready for the car wash.

      Fluid Change Questions

      By Chuck FB · Posted

      There would be one way of determining the quality of the factory oil although probably more than a typical oil lab test, and that would be to draw out some oil from a new truck and send a sample to a lab that could do a more elaborate test of the oil. The issue with too little oil in the diff may not be the lack of lubrication of the diff bearings and gears themselves ( although a lack of oil volume for cooling ) but the wheel bearings because at some point the oil would be too low to properly get onto the spinning axle or fed along the axle tube. That was the claim by the local dealer from a couple of trucks in recent years that had the wheel bearings fail and they figured from lack of sufficient oil due to a severe underfilled diff and some of the bearing material made its way to the diff and it got damaged as well so the axle housings were just replaced on warranty. But your right that if the diff is over filled by whatever margin that it causes more churning of the oil than is desirable and that is no good either and can cause a pinion seal to leak. Also old oil I believe can tend to loose some of its properties like antifoaming and another good reason to change the diff oil every so often.

      I would be surprised if the diff's were not filled (with the cheapest gear lube) at the axle factory before being shipped to GM.  If you ever watched them building trucks they install the axles and all suspension parts with the frame upside down and then turn it over before its time to install the engine.     Too much gear lube in a axle can be worse than not enough especially with a lower quality GL where is get whipped up with entrained air (foam)  weakening its ability to lubricate.

      This is the 6.6 gasser section of the forum, you should either delete or modify your previous post as it is misleading for anyone looking for factual information on their 6.6 gas engine.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Well....I've done my first intake gasket. Probably wrong, but...we'll see?   Ultra black on the china walls and 1/4" up onto the sides of the intake gaskets. Permatex High Tack (couldn't find Gaskachinch) on the head side of the intake gasket. I read wrong and it says you're supposed to put it on the mating surface of the head, not the gasket. Hoping it's like a PB&J sandwich where it doesn't matter what side the PB goes on so long as there's jelly. That crap is messy/sticky and I got a dab or two on the intake port openings, tried to wipe it off. Hopefully it won't be a big deal and will only aid in sealing.   Per instructions I left the intake (top side) of the gasket dry except for a light smear of RTV around the coolant ports. Wiggling the intake in there was a bear but I had help to free me of surrounding wiring/stuff but I was basically able to set it straight down lined up with the bolt holes.   I did not think to wait until the RTV skinned over but there probably was 5-10 minutes while it sat before installing the intake.   Bolts finger tight first. Then, followed the Chilton's manual pattern to snug them to 15 lb-ft.   Waited a little over an hour, and then did the final torque in sequence again to 35 lb-ft.   Yesterday I replaced the fuel pressure regulator and got my new "nut and bolt kit" (fuel lines) installed. Damn GM used security torx on the spider, which I don't have, so I got scammed at the local HW store for an off-brand security Torx bit set.   The new driver's door mirror arrived yesterday, so, there's a chance this thing could be running and road legal tomorrow? I don't want to get my hopes up.   This will be my first time stabbing a distributor, too. Although, lucky me, someone else marked the old distributor for removal previously, I did see that. (Someone's been here before!!). Engine is still at TDC so it *should* be just a matter of transferring the mark to the new dizzy and rotating it into place.

      2027 GMC Sierra: Official Discussion

      He has his dad’s newer truck he’s put away. He has several old cars he rotates between him and his family. I’ve seen a restored square body and a SS Chevy truck he’s sometimes drives. He did raffle off a new suburban recently. As much as he is watched if he drove new stuff as a rule we’d know it. It would be fine by me. I don’t care what people prefer. I got one more new one in me. I’d rather my wife get one. I can’t get her out of the Genesis. Don’t tell anyone. I want her to get an electric truck. I want to put a generator in the back. Just because. She hasn’t bit yet.
