Chevy Silverado and GMC Sierra Transmission Problems

  • I already posted a reply to you but I wanted to see if there were any other similarities to our experience. I my case it was it was about 5 degrees F outside. I was travelling on a straight flat highway at 55mph with the cruise control engaged. The road conditions were slippery but I had not lost traction in any way. I did not touch anything when the incident occured but did hear a bang or a thump when everything started happening. Did you have any similar circumstances?
  • I am also getting the "our engineers say it is operating as designed" story. customer service told me "if it does not show up in the diagnosis, then there is nothing wrong" yet the jerking in my transmission remains.
    I told customer service that my dealer scratched my truck the first time I took my truck in for this problem and I asked if the scratch shows up in their diagnosis. I guess not because the dealer is not going to fix the scratch either.

    I hope all our tales of owe reach potential GM truck buyers before GM sells one more truck.

    if you are reading this and have not made a decision on your next truck purchase, please consider another manufacturer.

    AGAIN, I own a 2011 Silverado with a 5.3 motor and 6 speed trans with less then 3K miles on it and the transmission has been a problem almost since day one.
  • GM, I have two 2010 chev 2500HD 6 speed auto/manual work trucks each with less than 3200 miles on them. Both are used for snow plowing. One of the trucks continues to throw the check engine light on and when this happens I lose my indicator light on the column PRDM1. I am able to accelerate in reverse as normal. When I try to take off in D M or 1 I can feel the tranny is stuck in 3rd (or higher) gear. I at that point must turn the ignition off and restart the vehicle until the indicator light on the column shows which gear the shift lever is in. It is not uncommon to have to restart this vehicle 20 times in a row before the computer resets and the tranny shifts as normal again. I have had the truck to 3 dealerships now and they are telling me that the code indicates the vehicle is being shifted while the vehicle is still moving and or the rpm's are too high when the initial shift is made. If this were the case why wouldn't both of these trucks be throwing codes at me and the shifting issue be happening in both vehicles? The tranny does not get hot ever while plowing. The vehicle is not being shifted improper. I have personally plowed snow for 25yrs and have driven both trucks this season. My father has been plowing for almost 50 yrs and has also driven both trucks this season. Neither of us have had this issue occur outside of the vehicle that is currently giving us problems. I know as well as you do that the issue is not being caused by driver error. Do you have a fix available that will solve this issue I am experiencing? If not, do you have another place I can turn within GM that will fix this problem properly? Resetting or erasing the code is doing nothing other than causing me down time and irritation. I appreciate your help in this matter.
  • Sounds like we have the same trouble. Bought a used 09 silverado with the 4.8L v-8 and 4 spd tranny. Drove fine the first month or so, then started to act up. doesn't down shift properly. When turning a corner onto our next road, slowed down to about 30K, hit the accelerator and instead of gently picking up speed it slips into neutral and revs to 5000 rpm. Have had it into the dealer a few times and aren't getting anywhere. Problem is inconsistent and never happens when they're test driving it. Think I'll go back to Ford!
  • Ive got an 09 silverado ls with the 4.8 and 4 speed. ive noticed since i bought the truck new that when starting out from a dead stop it feels like the truck is about to rip the U-joints out of the drive shaft it jerks so hard. this Jerking happens when slowing down on the highway as well, especially noticed when the transmission downshifts from 3rd to 2nd, and from 2nd to 1st. out of fear i checked my u joints and what hard parts i could, and they are all in good shape.

    I have also noticed this transmission 'burning', if you will, transmission fluid. i havent wound any leaks in the transmission anywhere, yet I've had to have fluid put in the tranny about every other time ive changed the oil. this is ridiculous for only 28k miles.
  • My 2010 silverado 4x4 did the exact same thing on tues. feb,8th. I took it to the dealer and got a call that the problem is one they are experiencing, caused by a flaw in the throttle body. they said it will take days to repair as GM is only releasing the repair parts on an "as needed basis" The dealer is Del Chevrolet in Paoili,Pa. I will keep you updated as I get results and/or responses from the dealer.
  • I have a 2003 Sierra that is doing the same thing. Didi you ever find out what caused the problem with your transmission?
  • I haven't found out yet, but i'm going to see if theres anything that I could change about my driving style that would help it... assuming its similar to other problems posted on this forum and it deals with throttle body position and an O2 sensor then there has to be a way to fix it, whether it be driving very very very gently or hopefully another, simpler fix that GM would come up with.....

    Bardol,
    I apologize that you are experiencing troubles. Have you taken your vehicle into the dealer? If not I would recommend doing so for diagnosis.

  • I have a 2010 GMC sierra with trans problems as well.. it started as a whine at about 10000 miles and just every now and then. Then at 12000 it was every day so I took it in to the dealership. They looked at it and also the AC smell I told them about. Ordered part for AC but said they did not know what the whine was...Part came in for AC so I took it back and they installed the "kit" and it fixed the AC problem so far..Said they ran tests and needed a torque converter.. Ordered part...waited and it came in.. RR torque converter and same issue...did not correct problem...RR power steering pump...said it was fixed...went and picked up and did not make it out of the dealership and whine was back...Left truck again...RR alternator...RR water pump...RR tentioner...whine is gone but now it has a new noise coming from trans...when slowing down and then getting back into the accelerator it sounds like it is searching for a gear and then "clicks" changes to a lower gear and noise is gone....Does this off and on on every trip I take in the truck..Went back to dealership today to have exhaust leak fixed and had the service manager ride and listen...said he could not hear the noise I was describing....finally got tired of driving him around and him not able to "hear" it...He was nice just no help in the matter...Noise is hard to explain so I was hoping he would listen and be able to help..Still have not got the trans problem fixed but was told it is probably nothing to worry about...$36000 to me that does not perform and make strange noises from a major part of the drive train is a worry to me...

    I read your post now I don't fell left out. I was talking to someone today and they said it could be the trans is going again? In my truck. I pull a 2 horse trailer and there a dressing room on it. For a 1500 my truck pulling alot of weight. I am looking at replaceing the truck before I lose every thing. I don't have the money to really buy any thing so I will shop around. I am thinking of going with a Ford F-250. I replaced my trans at 110,000 miles and just this past summer it started with the R thing. Its been getting worse as the winter been going on....
  • 2010 Sierra now has 3500 miles on it. It has tiny rust spots all over the sides
    of the truck. Have been working with the dealers body shop foreman. Today the body shop tried an acid wash to neutralize the rust spots. It did not work.
    The shop foreman said he will contact GM to see what the next step is. I've
    heard the GM excuses (thru my dealer) from the tech service department. Rail
    dust etc. Don't really care what the excuse is. If I wanted a rusty truck I
    would have bought used. I am pleased with the way my dealership has approached this, so far. Since I'm disgusted with this vehicle there are a couple other things I don't like. The new 6 speed auto trans shifts into 5th gear when cruising around town at 30 mph. And apparently the Active Fuel Mgt shuts down 4 cyls at the same time. I am very unhappy with this truck. Even if they gave me back $10,000 dollars of my $30,000 dollar investment I don't like this truck. $10,000 is what I could have saved buying the same truck used. I am very disgusted with GM. Thanks for the brand new rusty truck.

    If tech says it's rail dust, the correct procedure would be to clay it to remove all the impurities. You should make your dealer aware of this since claying wont take long or cost much compared to how he may ruin the finish by buffing it.
  • I have 145,000mi on my truck and the same problem started long time ago. I had all kind of stuff done on the transmission and everything looked good in there. Then I realized that it would do it more after a long drive and I also notice that it would only do it if I was running on Gasoline; it never does it when I run it on propane. They checked it more and realize it had nothing to do with the transmission but with the oxygen-gasoline mix. The sensor sends wrong signals to the transmission and it asks the transmission to shift faster as if you were really pushing it. I didn't change the sensor since it was very expensive, I just turn it off for a few seconds and it goes back to normal. It also helped a lot that I tuned it up. It hardly does it anymore.
  • I have a 2000 GMC Sierra with just over 200,000 miles on it. Yesterday after I had been driving for about 15 minutes around town, I was stopped at a stop light on a slight grade. When the light changed, I starting to give the truck gas but it did not immediately go. I kinda felt like it was creeping up the hill very slowly for a couple seconds. Then after a couple seconds it started to go like normal. Do this sound like a transmission problem? If so, what could it be?

    I own a 2011 Silverado 1500, 5.3L V-8, 6 speed transmission. When driving with the cruise control set, if I push the tow/haul mode button on the end of the gear shift lever, the light on the instrument panel comes on as it should, but the transmission will not downshift into tow/haul mode unless I deactivate the cruise control. The only way to use the tow/haul mode is to activate it before setting the cruise control or deactivate cruise, turn on tow/haul mode, and then reactivate cruise control, if desired. I just traded an exact 2010 model for this one and I could activate tow/haul mode at any time whether the cruise control was set or not. Is any one else experiencing this problem? What is GM telling you and what is the fix?

    I have an 03 Sierra 1500, and I am experiencing instrument cluster problems. The speedometer pegs at 120 mph. I had heard that there is a recall on this problem, and was wondering if anyone has any information on this. Also the tow/haul on the shifter will not activate no matter what I do. Does anyone have any information on this as well. Any help will be greatly appreciated.

    Us too-I'm cross posting this under TrailBlazer and Silverado problems:

    Mar 10, 2011 (10:09 am)
    Below is the complaint (personal contact info removed) I sent into Chevrolet's website on 3/6/11 under their customer service contact section. Up until yesterday morning they had not responded. I had to call the 800 # after we dropped TrailBlazer of at the dealership. Still waiting to hear if it is the same problem, but it certainly feels like it. Last time they offered nothing towards repairs so I hope they stand behind their product this time. (After all didn't the tax payers stand behind them via a large bail out?) If not, I will pool all resources at my disposal to try and get GM to recall these unsafe/unreliable parts. Maybe a class action suit like another member posted will be necessary...?

    2003 Chevy TrailBlazer EXT
    2003 Chevy Silverado

    In December of 2007 the Silverado would not go into reverse. Parts 24224999 valve assembly, 24221142 plate PKG, 24208576 FLTR kit were replaced at Pellegrino Chevy in Westville, NJ. Repairs completed on 12/8/06. The mileage was 29,578. Was covered under extended warranty we bought-out of pocket costs $0.00
    In December of 2007 the transmission was slipping badly on the TrailBlazer. It seemed unable to go into third gear. Parts 24224997 valve assembly, 24220200 F-plate, 24221350 GSKT kit and 24208576 FLTR kit were replaced at Pellegrino Chevy on 12/21/07. The mileage was 84,568. Out of pocket expense $1087.59!! Appears to be same exact problem. Called Chevy and complained. Received GM Loyalty certificate good until February of 2009 towards the purchase of a new GM. Still have certificate as our Chevy trucks were still quite new to us and we were NOT interested in buying a new vehicle. Fast forward to today. The transmission has slipped again on the TrailBlazer. It is Sunday and I was entering a highway trying to get up to 50 miles an hour, with my 14 year old son with me, when the engine just started really revving and the truck was barely accelerating. This is seriously unsafe and if it does turn out to be the same problem I will be most unhappy. We could have been rear-ended! The TrailBlazer only has 104,000 miles and change so it made it just about 20,000 miles for the tranny to fail again. I would really like to hear directly from a customer service rep before I put it into the shop-again. There is nothing I can do with it on a Sunday afternoon anyway.
    Thank you in advance for any and all help,
    Gina and John S., loyal GM owners.
    P.S. I'm glad I have a 1991 Camaro as a back up vehicle or I would end up renting a car and/or missing work.
  • Tell everyone and continue to tell everyone. We're still fighting with GM over our 2009 transmission shifting issues. It has gotten worse the longer we've owned it. My husband and my Dad were both GM guys. My Dad has passed away now and my husband still wants to be a GM guy, but is beginning to think otherwise. GM won't stand behind what they build .... we shouldn't stand behind them.....I think we need to do a major lawsuit and demand our bailout money returned to us. I haven't owned a GM in years and I will NEVER buy another GM product!
