Three problems related to transmission failure have been reported for the 1997 GMC Yukon. The most recently reported issues are listed below.
The transmission failed at 140,000 miles, however it was not clutches or bands, but a "hardened" part in the tail shaft, since there was no warranty I had to pay to replace the transmission, the replacement would not up shift, and I am not sure I can trust the vehicle to continue to perform like it should, I think gm needs to address this problem, if we have parts that are supposed to last forever breaking, it sounds to me like they have a reliability problem!! I think they should pay for the replacement!.
Transmission. Replaced when the car had less than 5,000 miles on it, the replacement transmission failed, I was told, as the direct result of towing a 7,300 pound RV on flat terrain in overdrive. My owner's manual states I may tow in overdrive. I paid.
