I would definitely recommend taking your vehicle in to be diagnosed. Please keep me updated on your progress.

I was accelerating from a stop sign and suddenly lost drive in all ranges plus no 4wd. When I inspected underneath the truck I noticed that wire harness that holds the switches for the transmisson and and transfer case had somehow come loose and all of the wires got riped by the one of the drivelines. I also had a blown fuse on the 4wd fuse. Long story short, I fixed the wiring, replaced blown fuse and ended up replacing torque converter and put the transmission back in the truck. Now when I start it up (with the rear axle jacked up) the rear axle does not spin unless I rev it up. Now the weird thing is that it spins the same way in drive than it does in reverse. Do I have some wires crossed here or what? Im stumped! Any insight to this matter would be greatly appreciated. Thanks,
Matt
I have a 2003 1/2 ton extended cab that sometimes feels like it is slipping out of gear (only for about a 1/2 second at a time) The odd thing is that I noticed that when it happened, the temp gauge would drop to the coolest !!!
I could not think why the two things would be related, but maybe that is the problem.
Will it get worse if not addressed, and about how much would the dealer charge to fix/replace the "Heat Temp Sensor"??
THANKS !!!
Was the dealer about to fix your concerns? Please e-mail me and keep me updated on your situation. Thank you!

has anyone experienced a whining after shifting from 4x4 to 2x4? This has been happening since I got the truck and no one at the dealer seems to know why. We've taken out other trucks and they don't make the noise. We've had the transaxles apart and no sign of wear. It drives me nuts as it gets worse in the colder weather. If you move the 4x4 shifter back and forth just a little sometimes it will stop. It sounds like the front axles haven't fully disengaged.
Thanks for any help
The fluid leaks down into the wiring that impacts the CC and other electronics.
Can you please e-mail me with your VIN, current mileage, involved dealer, and complete contact information including a good number to reach you at? Please also include a summary of your situation including how many times you have been to the dealer. I look forward to hearing from you!

As well as the same transmission being offered in a number of dodge pickups
Don't drive or you could do more damage to transmission ! Just something to look at ! GoodLuck
Torque Converter Control hydraulic circuit could be worn. You might need to replace the Torque Converter !
thanks
my dealers service manager drove my truck, and he heard and felt the hard shifting then told me they can't fix it and there is nothing he can do for me, he said its just something I've got to live with it.
wow, I didn't know what to say. I just spent 40K on my dream truck, my first ever NEW car ( I am 45 years old ) and I hate driving it.
anyone else with a low speed hard shift problem?
i have the same issues. hard shifting and searching for a gear between 40-50.
i was told this is a "learning" transmission. 9000 miles should be enough to correct this problem.
service rep rode with me says there is no fix.
will be taking it back soon to complain about this horrible issue.
never had a new vehicle transmission/engine perform as poorly as this and according to everything i have read and continue to read this is not an isolated incident. it is time for GM (who received all our tax support) to step up and admit this problem and fix it.
I wish I had read up more about these trucks before buying. I looked at a Dodge for less money but the same options, maybe I should have bought it. I don't understand how this can be allowed to continue.
I just made my first payment, I wonder if I can return it?
this is great, I am trying to write a review for my truck just over to the right of this message and it will not let me.
I am trying to worn others and I get the run around even here, not just from GM.
I understand your frustration and apologize. Please e-mail me with your complete contact information (mailing address, phone, first & last name), VIN and current mileage, and the involved dealer. I would like to address this issue further with you through email. Thank you!

2011 with 2K miles and the transmission shifts hard and makes noise.
I plugged my laptop into the diagnostic port and monitored the TPS (throttle position sensor) and the RPM. I increase the engine to 2000 RPM them quickly removed my foot from the gas peddle. When I removed my foot from the gas peddle it took almost 8 seconds for the TPS to go down to idle position. I tried the same test on a 2002 Cadillac and a 2007 GMC Envoy. Their TPS went to idle immediately upon removing my foot from the gas peddle.
My 2010 Silverado is currently at the Chevy dealer to get this taken care of.
This explains why sometimes when making a quick stop it is jerky. It's like trying to stop with your foot on the accelerator. This may also explain the poor gas mileage I am getting compared to my '05 Silverado.
What I need to know is if this is unique to my truck or do all 2010's have the same problem. I took it to my local dealer and, as expected, they reported that everything was within specs.
Thanks
If you are unhappy with the diagnosis at your dealer I would definitely recommend taking your vehicle to another dealer for a second opinion. I would ask them if the delay is normal and if this has to do with your fuel economy. I hope this helps. Keep me posted!

Christina. I may have already talked to you when I had the BBB complaint filed and I had a daily conversation with the GM lawyers and engineers about this widespread problem.
Thanks
We learned that it takes 8 seconds from the time you release the accelerator until the time the TPS gets to idle position. What's more alarming is at the 20% point it holds for about 2 seconds before going lower. This is about 1100 rpm. (For reference, 23.5% = 2000 rpm, 16.9% = 600 rpm, idle.) If you try to stop the truck within 5-6 seconds from the time you release the accelerator, you will likely feel the transmission jerk as it downshift.
This situation is particularly exciting (actually dangerous) if you are driving when the road is slick. When you release the accelerator you expect the engine to go to idle immediately to remove power from the drive wheels. When that doesn't happen, you are quickly out of control.
Here's the real kicker. When I went to my Chevy dealer this morning (3rd trip) I got a different customer rep. He was VERY interested in my graph. It turns out he just purchased a 2011 Silverado and has noticed the same problem, but didn't know what was causing it. He took my log information and is going to work on a solution.
If anyone would like a copy of my log, e-mail me at larrykoch@hotmail.com
I apologize for your frustrations. Since you are already working with the BBB and GM lawyers, you will need to continue in your course of action.

the service tech road with me and he said he heard and felt the hard shifting but he said its something I have to live with. " they all do that" were his words. then I was told I should take my truck to another dealer for any future service. WOW!
my tax dollars helped bail out GM and this is the thanks?
2K miles on my 2011 truck and I HATE THIS THING!
i have followed this forum and researched other sites to confirm that our issue is not isolated. gm knows this is a problem but, they obviously do no intend or know how to fix our vehicles. i have been told by gm customer service that my 2010 sierra six speed transmission is operating as it is designed. that is bunk. i asked for an address for the gm vp of customer relations but, they will not give it out.
they say there is nothing else they will do.
i also get the "go to another gmc dealer" answer.
this would be a nice truck if my transmission shifted correctly.
ford six speeds DO NOT jerk and search for a gear. neither should gm.
gm needs to be proactive and address this issue while they still have an opportunity not to alienate past, present and future customers.
does anyone have an address to any position above the normal customer service?
i see that customer service does monitor these forums but, it is apparent that we are all getting the same response.
but here is a thought, the service rep told me the transmission is operating at normal factory spec.s, hard shift and all.
this tells me hard, loud shifting is a characteristic GM has purposely built INTO 6 speed transmissions?
I should have bought the Dodge.
