GMC Yukon, Yukon XL Transmission Problems



  • 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.

    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,

  • 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.

    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?

  • 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?
  • Greywolf,
    I pretty much had the same issue.
    Hate to be the bearer of bad news.
    Cost me $2600.00

    Good Luck
  • Ughhh... Hope drive train is still covered. I think it is to 100,000 mi.

  • I've been reading threads on tranny sounds on Yukons and I there are so many I could spend the next month doing only just that and never finish. Wow.

    I recently purchased a 2002 Yukon XL 1500 4x4...132,000 miles. First day I drove it (online purchase) I discovered a whirring noise from under the console. THe noise whirrs a little bit on accelertaing, but it is worse on letting off the gas at any speed. Of course, I can really hear it when I let off the gas under 45 mph. It will whirr even if I let off the gas at 10 mph. Doesn't really matter what speed. The noise stops instantly when I put it into neutral. Doesn't whirr in park or neutral, moving or stopped. Once I get to the stop sign or red light and stop, the noise quits. It also quits as soon as I apply a little gas. The sound is almost like new tires buzzing on flat asphalt.

    Any ideas?
  • Is the Transmission issue with the 05's? I have a 2005 GMC Denali XL and the transmission is going bad. 2 weeks ago the ignition fell apart inside the steering when when I got to work and now this. I have always bought GM vehicles and I've never had a problem out of all 8 of my GM vehicles that I've ever owned. I had a 2003 Denali XL and never experienced a problem. Anyone if GM plans on recalling these transmissions or helping out with the cost of replacing them? My husband has a 2006 Mercedes which had a transmission problem last year and Mercedes and the dealship paid to have the transmission replaced.
  • just paid a $3250 bill for a transmission for my 2007 gmc yukon xl with 73000 miles.i bought it new and always maintained it as scheduled even stuck $850 into it 11000 miles ago for preventive maintenance including a tranny flush and new filter.accelerating from city to highway driving without any warning "bang" and it jumps into neutral.i got it rolling again to nurse it home the last 60 miles taking it directly to the dealer.3 days later service writer called and said $2700 for a rebuild or $3250 for a new one.i talked to the gmc distict rep about the reliablity of the vehicle and how it was always serviced never stuck ,plowed snow or towed a heavy trailer.he offered me a 15000 mile service package" whoopee".i wasnt interested as i plan to replace the vehiicle soon. do you think it will be another gmc? should have took that $850 i stuck in preventive dollars and bought a extended warranty policy.

    Like so many others, my transmission failed on my 07 Yukon. 56,000 miles - well under the 100,000 mark and less than 2 years past the 5 yr warranty. $3200 to replace.
    After a week and a half and 4 different reps telling me they are contniuing the escalate my case, GM came back with $0 in assistance....but they did offer free oil changes tire rotations for 2 years....great.
    This will be my last GM purchase. Professional Grade? Not so much...
  • HI
    I have a 2007 Yukon XL, 5.3L, 4Wheel drive (rarely used) and I recently took it to my dealer in Las Vegas for strange noises/delays when switching between 2 and 4wheel and engaging the transmission. They said it was the transfer case, it was gone and needed all new guts, fixed under Vehicle One warranty which was due to expire with a few hundred miles! I was happy. 4,000 miles later, Transmission blows up, not repairable they say, needs a new one at $4200! I said you need to talk to Vehicle One, this is related to my complaint when I brought it you 4k miles ago. Vehicle One says no, out of warranty. Service manager is now working his way up the chain within Vehicle One, trying to establish these are related, they need to Goodwill this or do something. But its not looking good.

    I have Vehicle One's rep number in the Las Vegas Area, anyone got a winning strategy on getting Vehicle One to just fix it?

    [This car was bought at 64K from the servicing dealer, all service there, all the proper scheduled maintenance. I bought a 50K Vehicle One warranty covering me to 114K. All highway miles in 2 wheel drive, 4 or 5 towing trips between Vegas and LA, 4 or 5 times in 4 wheel (no trailer) due to mountain snow]
  • 95,000 - heard a couple of clunks - then nothing. I was able to get it moving enough to get off of the main road by pressing the traction control button - rebuilt GM tranny - $3200. Ugh!
