My 2004 Yukon XL tranny just went out at 80K miles. Never pulled anything...always treated kindly...and boom...the tranny is gone. Really makes me sick. This was a great truck until yesterday. I thought about calling GMC but I know they won't help. Oh well, I am having a Jasper remanufacture installed and will drive till it drops...which may not be too long~!

2007 Yukon Severe Transmission problems by yukon6

Our 2007 Yukon Denali XL had its first transmission failure at 1,850 miles. At 55MPH it came out of gear, would not re-engage until we turned the ignition off and on three times. Limped back to the dealer with only 4 operating gears. The dealer rebuilt it. At 2,430 miles, while in the Sierras outside Yosemite at 2500 feet, the transmission heated up to almost 200 degrees (outside temp only 78), and it came out of gear again. This time it would not shift out of first gear until we let it sit overnight. Drove it back to the dealer. Now they are talking about putting in a new transmission.
 
While at a meeting with some business friends, I found out another 2007 Yukon owner and a 2007 Suburban owner both had the same problem! The dealer was replacing the Chevy transmission at 15,000 miles after the transmission failed, would not come out of third, and heated up so bad the transmission was toasted. The other Yukon owner had a complete transmission failure while on vacation and the vehicle was not drivable. The dealer replaced the transmission. Coincidence or a fundamental design problem?

Its difficult to say these transmission problems are design related or not unless there is a significant amount of failure within a same model, year and type of transmission... In this case, it is my opinion, the quality of the parts used (GM's parts vendor) are in question as well as the transmission assembly quality. It would be interesting to learn if the two Yukons (possibly also the Chevy ??) mentioned in your post were assembled out of the same plant and each built date...

Thanks for your response. I will check with dealer to see where my transmission came from. When the first transmission problem occurred I checked for TSB's (tech service bulletins) and postings on the net. I found a major gear assembly problem that was leading to catastrophic failures which supposedly was remedied by 2007. Another neighbor of mine had that problem with their Yukon.

Our 2007 Yukon with the two serious transmission failures in the first 2400 miles was returned as "fixed" today. This time an internal solenoid was replaced. We shall see what happens next. How can you trust any vehicle that fails this much in such a short time? If you are considering a new Yukon DONT! Check out the transmission problems on the internet.

I just had the same problem with my 2003 Yukon XL--only 84,000 miles. The dealer quoted over $2500 for a new factory transmission. Would you recommend Jasper remanufactured as a better quality option?

Good luck on the transmission. i just had a third transmission issue at 2650miles. Jasper might be OK just make sure there is some type of warranty.

Sorry to hear about your transmission problems, isn't there some kind of lemon law that may be able to assist you by having the same problem within such a short window? By the way, do you have a 5.3L Engine 4-speed transmission or the 6.2L with 6-speed?

Yes I would recommend Jasper. Make sure you get the three year/30K warranty.
 
UPDATE:
GMC (customer service) paid me 60% of the $3000.00 tranny repair bill even with it being OUT of warranty. Gotta love those guys~!
