Well, that's the short version. So, we bought one of the first of the current gen Yukon XL to arrive on the dealer lot in my city in May 2014. It's an SLT 4wd with tow package. The only previous transmission issue we had was about a year or two ago, a/the solenoid for shifting in/out of 4wd went out and stuck us in 4 low. I didn't fool around with that and had it towed to the dealer (on a trailer).
Flash forward to a week ago last night, my wife tells me she felt a little hesitation in 1st while she was out of town on a weekend trip. Seemed minor. The next day, she calls me upset telling me she thinks her car is about to break down and she almost hit someone because she's pressing the gas and nothing happens then the car takes off. I didn't even think slipping transmission. I thought it might have been one of the "hesitation issues" I've seen discussed on here and other places. So, I had her take it to the dealer that evening. The dealer waits 3 days then calls me late Friday afternoon that I need a new transmission to the tune of $4,400. Said "the torque converter went out and there's metal everywhere and it's lodged the valves open." I didn't know what to think and I wasn't going to tow it somewhere else for a second opinion. The next day was Saturday so we briefly looked at new Yukons before I told her I wasn't paying that much for another Yukon when the transmission went out that quickly or at least the dealer was going to try to fleece us for one.
It just doesn't make sense. I've driven a ton of Chevys for work trucks over the years and never had a transmission issue. Then I throw down over $65k on this beast for the wife and this #%$& happens. I've only towed with the thing 3 times over 4 years. Thought we were gonna get a boat but...we didn't.
