My "new to me" 08 Yukon XL Denali with 80k miles will soon be getting all of its fluids changed. It was a grocery getter and not a tow vehicle during the first 7 years of its life. Along with the differentials, transfer case, coolant, and engine oil, I'm going to do a transmission filter and fluid change out soon.
Do I stick with the oem tans fluid by ACDelco? Or should I consider national brands like Valvoline Max life ATF, Amsoil or Mobil 1? What do these 6l80e transmissions like to drink?
She's a dedicated tow vehicle for us...and will be pulling a travel trailer all over the midwest.
