True, Lots of miles but I really enjoy this vehicle. I use it to field service airport equipment throughout the midwest. Its mostly highway miles. In the first year i had several problems: bad torque converter, bad radiator, bad a/c condenser, but seems to be ironed out now. Burns no oil.
OK guys 1st post. 2015 GMC Yukon XL Denali. 171,300 mi. 8sp trans. I just did a pan drop, filter and refill with Amzoil Signature fuel efficient ATF. Also did the same thing 50K miles ago. The old fluid looked and smelled fine, it was just a little darker shade of red. So far I'm happy with Amzoil.
