GMC Yukon, Yukon XL Transmission Problems



  • You're not alone on this. I made the fatal mistake to try again with GMC. We first bought a 2002 GMC XL Denali. At about 56,000 miles the transmission dropped. Called GM and asked for them to help with the transmission since it is inexcusable that you pay this much for a car and at 56,000 miles the transmission goes? Would not budge. I have 4 kids so I need a reliable car and we don't want to buy a mini-van. 2 years ago we traded that in for a used 2007 GMC 5.3 XL just like yours. While looking someone mentioned that GMC and Suburbans are known to have transmission issues at around 55,000 miles. We ignored the warning and bought the 2007 GMC Yukon SLE XL. Like you we are starting to get the hammering issue with the transmission at 65,000 miles. When we accelerate from a stop position it hammers (bangs) or jumps into gear. I'm sick over this car as we can't afford to pay $3,000 for another transmission. I have never experienced a vehicle that has so many predictable issues. Even before this I was so paranoid that I swore I felt the slight hammering at about 50,000 miles and asked my mechanic and he could not detect it. I'm not sure if this will save me from paying for the fix since they have it in the system, but I'm sure they will weasel out of it somehow. I also had a steering fluid leak back at around 52,000 miles and GMC did honor the fix as it was close to the warranty. I'll give them that but for a car like this to have issues is ridiculous. I should have learned my lesson and not bought a GMC again. I have zero faith in this car or any GMC or Suburban and feel like I could break down at any second. I go on vacation with my family and I'm always praying we make it back and don't break down on some back road. Whats worse I'm concerned my wife and kids don't have a reliable vehicle and could breakdown somewhere. With such a big family (6 of us) I have few options other than a minivan. One thing I do know is I'll NEVER buy another GMC or Suburban again if this 2007 has yet again another transmission problem. A Ford Excursion or Range Rover L4 can't possible be worse. BTW, If a class action does develop I'm on board.

  • Another one here. I have a 2003 Yukon XL with the exact issue you mention about punching the gas and the rpms surge but no acceleration. I'm trying to get prepared for the $3500.00 expense to replace the transmission. My truck only has 74k on it. This is absolutely ridiculous that a $45K vehicle can drop a transmission after 74K miles. I really wanted to keep this vehicle for a lot longer but after seeing all the failures here I think I'm going back to the imports!!!
  • GM opened a customer service issue for me. a rep returned my call. she said no way she can help because just-over 100k miles. so maybe you have a chance. it took a bunch of emails and phone calls, but finally spoke with someone at gm. i am starting to wonder if it is Ethenol in gas!!! my other vehicle was fine when i got it out of storage, now it is acting up too. Dealer would rather sell tranny than a $8 additive or carb cleaner. I have NOT tried either yet, but it's a thought.
  • My prior posts #95 & #115 are exactly in line with your thoughts. As much as I also would very much like to see an organized effort move forward, yet this forum is still awaiting someone to take the lead. When this does occur, count me in!
  • Well if any of you open up a class action lawsuit include me in. The transmission in my 2005 yukon denali has gone through 2 transmissions, am AC unit, and a list of mechanical items that is ridiculous for a vehicle this age. Class action lawsuit...Lets all go because it is only going to get worse and GM could care less! They told us to take a jump! Really? A vehicle that costs 55,000 and thats the kind of service you have well screw them, I will never buy another GM nor will my friends, family or co-workers and I live near the plant. So who will have the last laugh!

    We're sorry to hear that you've had these troubles with your Yukon; had you already worked with Customer Assistance on this?

  • Took my Yukon to the dealer on today due to tranny jerking and hesitating from 25-50 mph. Its subtle and sometimes it's rough. I also get that "bump" that you guys keep talking about. I only have 50000 miles on it! They haven't given me a complete diagnosis yet but the general mechanic believes something is wrong internally in the transmission. Since this problem has arisen my mpg has dropped to 14.5. The dealer also alerted me of a recall on the tranny dipstick. It has the tendency to crack! And mine already did.

    I remember when my dad had a 68' 442.....indestructible!!!

  • I have 3 with similar but different transmission problems. All over 100k. the one i bought new is at 105k. The lady at GM insist that IF is was less than 100k they could do something about it, but since not, then to bad for me. Well she didn't say that last part but that was effect. I have her name and number if you want I can probably find it.
  • Did she say it was if the truck was under 100K? Ours is at 120,000. Yeah what a deal. Nice vehicle, fully loaded to the hilt, but really there needs to be a guarantee with these problems. Thanks anyway. Keep me in mind if you hear anything and I will the same for you.
  • I'm now joining this club of transmission issues at 112,000 miles. I was driving in a shopping area yesterday when I was attempting to make a left-hand turn and my Yukon made a loud bumping sound from the rear that sounded like someone had rear-ended me. Then the vehicle stopped, but the engine was still running. I couldn't get it to move no matter what gear.

    Fortunately, I wasn't in a normal street intersection or I could have been hit. I shudder to think about what COULD have happened in a higher-traffic area. Good Samaritans pushed me out of the intersection. Vehicle is now at a dealership and I'm bracing for what they're going to say when I get the call tomorrow AM.

    My Yukon - which still looks as pristine as the day I bought it built for me and brand new in January 2004, has largely been trouble-free save for a few recall issues, including the IP cluster issue that made the speedometer go wacky and a clunking sound that it made when I cut the wheels.

    I will be sure to report back on what I learn from this experience. Spending 3K+ on a nearly 9-year-old vehicle is not something I want to do.
  • I have a 2007 Yukon and this is the exact same thing that happened to me in November of 2011. I took it to the dealership and found out that a small band inside of the engine had popped. I spent $5000 to get it fixed. Once it was fixed I have had no issues. Good luck!
  • Yo bugger2023: >> Much like yourself, all of us on this forum have a similar experience w/the excessive early failure from our OEM 4L60E tranny. In order to pursue this ongoing scenario, perhaps this discussion should continue elsewhere devoid of mounting scrutiny??
  • Yo cjsly172, currently u don't know me, but after reading your seemingly exact re occurrence of the very same reason which has brought all of us here , was due to premature 4L60E tranny failure. Albeit this reply is ~3 months post following your breakdown. Yet each vehicle owner on this website is here for the very same reason, seeking answers and justification from the premature tranny failure of the 4L60E. Although I am not a certified ASE mechanic, after reading your posted story, I'd probably be 100% correct in assessing what your likely repair bill is going to be following what I researched and learned during my quite similar tranny reconstruction. In the event you have already repaired your vehicle, I'm curious to know what caused the failure and how the repair was handled. Please reply back when available.
  • Hello Sara,

    Yes we had worked with GMC and they said since the truck was over 100K there was nothing they could do even with the extended warranty. I am open to any suggestions you may have.

    Thank you

    Good morning bugger2023,

    If you were to email us at with either your service request number (71-**********) or the last 8 digits of your VIN, we could review the file and see if there's anything further we can do.

  • So the dealership called this morning and I'm looking at $3,300 to replace the transmission. I had no warning it was going to go until it completed failed on me Saturday. I did call GMC today to check on any recalls and there aren't any.

    This is a big chunk of change to spend right before the holiday season. Sigh.
  • I have read every post about the transmissions going on the Yukon XL. I see that some state a big "clunk" and yes, "Clunks" sounds like gears/transmission. Years ago my dad showed me trans fluid (when changing the fluid) big chuncks, meaning trans is going bad. I assume My problem is with the trans system, but I haven't had any clunking noises AND the trans stopped just days after a transmission fluid and filter change. The fluid and filter were clean... ie: no chunks. MY Problem/symtoms: For a few days, when driving the rpm revs, but truck doesn't "switch" immediately. When it does, no "clunk" sound or jerk. It just speeds up like normal. Yesterday, when driving, I slowed for traffic in front of me, but when I tried to accelerate back up, NOTHING HAPPENED. I just coasted... right into the intersection! I tried every gear but it just didn't move. No clunking sound. Engine excellerated, but no movement. As we sat there during rush hour for the police to come, I had left it in 2nd gear and all of a sudden, my truck started moving. Again, no warning, no clunk, no jerk like a gear "caught". It is like a sensor doesn't tell the trans to switch. What could some of the sensors/fuses be that work with the transmission? What else we can check???

  • Well,,,,,,, First of all it doesn't move. Second, my vehicle is OLD. Third, the Dealership is more expensive than local service company. Forth, no Dealership in my town, would have to have it towed to another town.... more $$$$. Five, just want to eliminate any other issue AND know that all bases have been covered before spending $3000 on a rebuilt transmission. (PS: I am long time friends with the owner of the closest GMC dealer and they do good service, BUT cost is very important. We have 4 kids in college and High School, Medical Bills still unpaid, own a business that has been hurt in the recession, etc.... Again, just want to eliminate any "low cost" fixes.
  • gmcustsvcgmcustsvc Posts: 4,251
    We completely understand, janschrock! I wasn't sure how old the vehicle was in your original post and had just wanted to get a better picture of how/if we could be of assistance.

    All the best,
    GM Customer Service
  • Sorry new to this posting stuff. We have a 2005 Yukon XL and do city driving. We kept up on maintenance and this morning my son was driving to school and had bad whinning noise. I see that there has been alot of issues with transmissions. Idles fine put it in gear and starts to make a whinning sound. Had it towed to tansmission shop they took the pan off and no metal in pan. He thinks something broke inside, big $. The care only has 69,000 miles on it. Is a transmission only supposed to last 69,000 miles? I find it hard to believe.
  • erv4erv4 Posts: 1
    Just started looking at all the posts about the trans problems with these trucks, I wonder what I'm in for. Mine has 110K miles and has been very well maintained. Oil was changed at 60K. Just began to experience an issue yesterday with no OD gear and shift points suddenly are at higher rpm.
    Anyone from GMCUSTSVC: Is GM doing anything about covering repairs to these transmissions?
  • gmcustsvcgmcustsvc Posts: 4,251

    I'm having the same transmission issue as hundreds of other people in this forum. Why should we all be spending this ungodly amount of $$ to fix this problem they caused?? When is GMC going to do something about this?? Cmon customer service person respond to me, I need help!!
  • gmcustsvcgmcustsvc Posts: 4,251

  • With 60,000 miles, my transmission is now acting up. While passing a car today, at full throttle, the transmission could not decide what gear it wanted. It geared down 2, back up 1, back down to normal passing gear. Also have "lost motion" in reengaging after coast. Also, rolling slowly into parking space, got a bang and lurch. Thought I hag been hit from behind. Anyone having these problems?
