For sale we have a really nice 2015 GMC Yukon XL. We purchased this vehicle with a bad transmission. Our shop rebuilt it and installed a lot of updates parts in it, including a valve body kit and a thermal bypass kit. We are offering a 3 year unlimited mile warranty on the transmission.
We have also gone through it and taken care of some of the other small issues such as installing new shocks and struts, fixing one of the power running boards, replacing leaking transmission oil cooler lines, etc.
I have personally used this vehicle to take my family on vacation pulling a large pontoon about 500 miles round trip. It performed flawlessly, and runs great with all of the work we have done to it.
We have this at our Winthrop location
