I use Mobil 1 ATF and the AC Delco tranny filter. There are two different pan sizes its seems for the truck, at least thats what the dealer told me. I had to crawl under the truck to measure the man depth to get the correct filter. One pan is deeper than the other. Turns out my truck had the deeper pan. I am not sure why there are two different sizes. They did not seem to know at the dealer. I got a "Thats just the way it is"
