I am getting ready to do a fluid exchange and filter change on my 04 Yukon 2500 with the 6.0/4L80 combo. My manual states Dex III, but I see a lot of reviews here tell folks to use the Dex IV in the same tranny. Which one should I be using? The truck has just shy of 100K. I don't know what the difference is between the fluids. I have searched a lot and am still confused.
I love these trucks, I have a 00 2500 Silverado with 200K and its still running strong! (same 6.0/4L80 combo)
Thanks for the help.
