Chris,
Mike better read the label on the bottle again. I checked with my
tranny man along with several others before I changed and the Mobil 1
tranny fluid is completely compatible with older organic based fluids.
I changed mine 2 years ago (12K miles) and the tranny runs great. Many
other GMC'er have done the same with no problems, but the choice is
yours to make.
