note: the above issues started at mid 50k miles and were repaired at 62k miles

I have a '17 XL (non Denali) with the 6-speed and also had harsh shifting. GM warrantied my transmission for a full rebuild and new (updated) torque converter. So far almost 20,000 miles after the repair and so far so good. GM gave me a 2 year unlimited mile warranty on the repair.

Hey all, Glad i found this post. I too have a '17 Yukon XL 4x4 and with factory 20" wheels and the 275/55/20 stock tires rub on the front side of the UCA. I have since leveled it with the Bilstein 5100 adjustable strut and got 275/60/20 All Terrain tires. Now it rubs so bad at lock it will stop the car! 1/4" spacers were tried and didnt help so we went to 1 1/4" spacers. NOW it rubs on the rear part of the front fender. Wife is pissed as this is her DD and is embarrased any time shes backing out of a parking spot. Rather than cut the fender I will most likely lower the struts to get it closer to stock and get rid of the spacers.
