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.
