GM Yukon XL Denali Transmission Temps
My main tow vehicle is my RAM CTD, but when we take the RV as well the truck has to pull my 7000 pound boat. So then we use my 2011 Yukon XL Denali to tow the Malibu. It has always run hot - both...

Towed the boat for the first time since I had the new trans cooler installed.
Just flat land down I76 and back. Cruise set about 70 MPH, outside temps in the low 90’s, most of the time in 5th gear running about 2400 RPMs, the trans never got above 180*. It spent most of the time in the 160* range. Before the cooler install it ran 200* - 220* on this same trip. Must say so far I am pretty impressed.
I’ll give it more of a test next week as we will be using it to tow the boat to Utah. The ride home will be the real test - eastbound over Vail Pass and the Eisenhower tunnel is where it would run up to 250*+ before. Will report back again.
