Tranny fluid change
Got 70,000 miles on the current ATF oil, so today it and the spin-on filter got changed. I also dropped the pan to see if there was any sludge and it was clean. Love this Duramax/Allison combo.

If anyone has figured out how to do a fluid exchange on an AISIN please post method. IMHO it's stupid to not remove all the fluid.
