GMC Yukon, Yukon XL Transmission Problems



  • I was driving home today and heard a loud noise like I had been hit and all of a sudden my truck slowed down. I pulled over and looked at the vehicle and saw no damage. When I got back in the car I tried to put the truck in drive and it didn't move. I put the truck into 2nd gear and was able to make it home. The truck will drive in gears 1 and 2 and will reverse. It will not move in Neutral, D (Drive) or 3rd gear. Does anyone have a clue on what's going on? Is it extremely expensive?
  • Sounds like the 3-4 clutches. Your looking at a rebuild. what trans do u have? **L65 or **L60? if you have the 60 u might want to do some upgrades on that model.

    I have a 2007 yukon with 90k miles. of course warranty just ran up 2 months ago and transmision stopped working yesterday. It works in PRN21 but not in D or 3rd gear. This happend while i was accelerating after a red light. Any thoughts anyone?
  • The transmission that is in the gmc's 4L60E & 4L65E have weakness in the 3-4 clutches. I am fairly confident that is your problem. You are looking at a rebuild.

  • It seems like this is a major issue with the transmission. I have just had the second one go out. Had the first one replaced at the local GMC dealer here in Montgomery, Alabama at 600 miles "outside of the original warranty", my cost $3500. Now, Tuesday this week, November 29, 2001 at 160k, vehicle won't move. Was working just fine, parked, went to leave, no reverse, no forward gear, nothing. Local dealer wants another $3500 for a NEW one, or can go to a Local shop and have it rebuilt for $2000. Sounds like GMC needs a recall on this model. Does anyone and any suggestions of any upgrades for a rebuild, any performance parts. HELP!
  • I agree that the transmission and the paint on these vehicles are horrible and should be recalled.
  • Sarah,
    As (one of) the latest victims of the bedeviled transmissions on the 04 Yukon :lemon: , I have been searching for a solution that will meet three criteria: 1) speedy repair, 2) inexpensive, and 3) permanent. I have been reading this forum and I have noted that you, as a representitive of GM Customer Service, acknowledged that there is a problem with this product and have confirmed a willingness for GM to fix the problem. But as was stated in a previous post, the $3500 repair job was not cheap, and now that the problem is back, it is NOT permanent. So, please let us, the sorry customers :mad: , know what GM is doing to help fix this problem.
  • Customer Service Representatives, like me, are able to set up customer assistance cases which are evaluated on an individual basis. As far as a more comprehensive solution, these customer assistance cases add to the database that GM uses to make larger decisions. Essentially, we are a starting place. While I cannot guarantee how a case will be resolved, I can say that we do investigate many things in our decision making, including previous service work.

    I hope this helps to clarify what I can do as a part of Customer Service. I understand that the process can be frustrating, and I apologize for that.

  • Sarah,

    I appreciate your response as well as your dedication. While I may be a bit cynical, I do believe in the addage "You get what you pay for." The sticker price for this Yukon was on the far side of $40,000! It has had numerous inconvenient problems and is now sitting idle with a bad transmission :lemon: .
    Staring down a $3K+ repair bill (not to mention a loss of confidence) makes me think "I did NOT get what I paid for." I don't see how a long history of expensive repairs changes anything. The transmission fails once or it fails three times, it still failed. Nobody is going to say "Boy, those GMC's have a bullet proof tranny!"
    My plan is to have it fixed and then sell it. :(

  • I am the original owner of a 2003 Yukon XL which has less than 60k original miles. I have meticulously maintain the vehicle using only Mobil 1 oil and dealer original equipment. The transmission recently stopped working in 4th gear. I can manually shift from 1, 2, 3, into 4, but the truck will not start off when placed in either 3rd or 4th gear. Anyone know what could be the problem? I have always been a GM guy, but I am extremely disappointed to experience transmission problems with less than 60k miles. Does GM stand behind their products anymore?
  • Is ur 2003 Yukon 4WD?

    Well I guess its time for me to officially join the discussion at 92k miles. My transmission is running hot and having problems with 3/4. I thought I was covered with the power train warranty, but the local dealer just told me I was 19 days too late. I am anxiously waiting to hear back from GM Customer Service. Not happy at all if I have to drop $3,000.
  • We have the same slippage problem as posted numerous times on this site and several others I’ve found. I drive my car everyday back and forth to work and I’m so used to the problem now that it's become just a part of how you drive it. We've had the transmission rebuilt and it didn't make any difference. The mechanic actually said he couldn't fix it. What do you do after that? The car slips when I slow down or come to a stop. It started happening when it was cold outside so i thought it had something to do with condensation - but nope not that. I love my Yukon XL and like everyone else, it wasn't cheap and we are still paying for it. I wanted to be pissed and I want to stomp my feet at GMC but I honestly, even after this disaster, i wouldn't by another brand. YES - I'm an idiot. . . . but i like this SUV. I didn't get into a bunch of details because it is the same problem as posted over and over again. We have tried the same things and we have exhausted our check book. I've emailed the CSR person who has posted on this site. I'll update my post with their response. Hopefully, i can add something positive. Again, I’m and idiot . . . . but wish me luck!!! and prayers go out to everyone else that your travels are safe!!!
  • I see you are already working with us, and am unsure as to whether or not you are working with Christina, my co-worker who helps with emails. Do you have a Service Request number? We can keep an eye on its progress, if you like. Please send us an email and we can get you an update on the progress.

  • I haven't noticed any followup on replies. I've recevied an email from Christina (Thanks Christina!) but no one has reposted their resolutions. I'm curious to know what the final outcomes have been.

  • I have a 1999 Yukon Denali that has just been through it's second rebuild in a year. It had problems right after the second rebuild and I brought it back to the shop, they repaired the problem. The transmission has worked fine for about 1 1/2 weeks but now when traveling at highway speeds the lockup seems to start slipping when going up even the slightest hill. once going downhill or level it seems to lock up again. If I step the throttle down or put the selector in 3rd it seems fine (but with the rpm at 3000 instead of 2000. The "Check Engine" light also came on about the same time.
  • Update: Went to the auto store and hooked up a code reader. Listed "Transmission Component Slipping" Drove back to work (Not far) and light did not come on. Trip home will be the big test.
  • I just replaced my 4l60e transmission with a heavy duty rebuild. It shifts fine from 1st to 2nd but the engine races when it tries to shift to 3rd. I just installed it yesterday, so i'm thinking its something electrical. What is the function of the module that bolts on to the outside of the transmission on the shift lever just before the shift cable? The shift lever goes through it and it has 2 or 3 electrical connections. Please give your thoughts.
  • I had my maintenance done on my truck and never pulled anything with it. I only have 102k on the transmission and now I've lost 3rd-4th gear. Is this a common defect on this unit? I had my cluster replaced two years ago through a recall? Should I have this rebuilt or replace it?
  • If you would like for us to check to see if there are any recalls on your vehicle, please feel free to email us the last 8 digits of your VIN.

    I posted on here a couple of months ago as I was experianceing slipping. would turn off the truck for 2 mins turn back on and it would work again. this lasted about a week then it slipped to bad. I barely made it to the shop. well the tranny was done.

    GM customer service contacted me thru here. but it looks like they are just trying to cover up a known faulty product. yes you can bring it to out facility they said. but if we find no issues you will have to pay ~$800for the tear down. Well of course GM is not going to find no issues with the OEM parts they put in the 46le for the Yukon / XL . Because they suck!!!! and last as just long as they were meant to, that is why you see people complaing of 3 and 4 transmission rebuilds.

    So here is my advice if anyone wants it. And I am by no means an expert. but I did do a lot of research before shelling out $2600 because for me that is painfully an awefull lot of money.

    Anyway the 46le actually IS a good transmission design. it is found in a lot of different product lines from the S-10 and blazer ( which I own and on 80,000 miles with no issues ( knock on wood)) to the corvette!!!!. and I guarantee the corvette can hammer on the transmission pretty hard.

    The problem lies in the components used for the yukon line ( corvette transmission use diffrent internals!!!). Plain and simple. the OEM internal componets used for yukon's suck and are under engineered and obviously judging by this forum to not last very long.

    So when I when to my tranny guy. I definately did not pick the cheapest guy. I sat down and told him what my expectations were from a tranny and what I wanted to do. in my case pull a 20 foot boat thru the mountains.

    so he DID NOT use oem parts on the rebuild. he put in a hardend sun shell. 5 gear planetary upgraded spragues, larger tranny cooler bla bla bla. all the upgraded stuff will cost a few more hundred extra dollars.

    Only time will tell for me if it will last longer. but I truley think the OEM parts are a bad design for the YUKON product line


    oh and as a footnote I bought my truck used and had to replace the tranny at the 120k mark. however the previous owner was the original owner and he had to replace the tranny at the 60k mark.

    good luck everyone
  • 2011 AWD drivr tran or transmissions or winding up and winding down so hard that when you stop it feels like some just tapped your back bumper. It is so dangerous that you have to reapply the break. It also happens during acceleration. This feels more like a thunk feeling. GMC continues not to accept their is a problem and explains that the way they are built. This is a big cover up.
  • Good morning,
    I see that you are experiencing some difficulty with your transmission. Have you already had this looked into by your dealership? I would like to see how we could be of assistance in addressing your concern.

  • Hello,

    I just wanted to put my two cents in this thread. I have 2003 yukon 4x4. transmission made whining noise last night. This morning it wont go into reverse. I purchased 2 new GM products at the dealership within the last 12 years this yukon being one of them. I like the yukon.. problem is that they are inferior products. I should not have to worry about a transmission at 149k miles. I already replaced the water pump, rear axels, unit that controls the shifting into 4 wheel drive. So disappointing. Of coarse after searching the internet "The sudden loss of reverse in a 4L60E or a T-700R4 is a common problem in respect to the actual amount of internal problems these transmission have" NICE!
  • I have a 2003 Yukon with only 83,400 miles on it and the transmission would not go into 2nd. After accelerating and letting off the gas then it would shift. After reading the posts here I knew I was in trouble. I contacted GM and they said IF I went to an authorized dealer "They might" be able to help. Again, after reading the post I decided it would be better to go to our own mechanic. Well, after testing the transmission hoping for the best that it was a sensor or leak in the line, the bad news came. After getting into the transmission it turns out the all the plastic parts had started to disintegrate! Like others have said GM cut cost by using inferior parts. I called GM today and asked if they would help pay for the new transmission. She told me only if you go to a GM dealer they MIGHT have been able to help. Why would I go and have them use the same cheap parts? I told the mechanic about this blog and he already knew about the cheap plastic parts and said he would never use OEM parts to redo a transmission. With that said...I'm thinking there should be a Class Action lawsuit agaist GM for using plastic parts in a transmission. Any takers????
  • I was told the same thing if I take my Yukon to a GM dealer they might be able to help. So I had my transmission rebuilt with no help from GM. Another problem I'm having is every time I run my Yukon and park in my garage I smell gas. So now I'm going to have to take it to the garage once again. Their is no leak under my Yukon when I park it. Once again trying to cut costs by using cheap parts! Good luck to you...I'll be glad to go on board with a class action suit!!!
  • Just dropped off my 2006 Yukon Denali at the mechanic with 66,000 miles. Transmission is toast. It is slipping when trying to take off, especially on a hill, and makes a squealing noise, as if 2 plates are trying to clutch together. While driving, it suddenly revs as the tranny slips.

    What a shame that the transmission only lasted 66K miles. I have loved the car until now. A high end SUV like this should last longer. Should have been a red flag to see a 36K warranty. My local GMC dealer has ripped me off on previous repairs, when they mis-diagnosed a loose oil filter. So, unfortunately, can't take it to them. I'll review Consumer reports very carefully on my next purchase.
