Phantom of the Opera
LONG time ago, I got to reading about modern stick shifts using ATF and much thinner oils in the trannies.....
the olde muncie in this '72 shifted like a tree trunk....so I up and changed over to 30 weight syn engine oil...Mobil 1.....and it shifted SO much smoother, and lasted some 3 years before I tossed it over for a automatic overdrive....
so it makes me wonder if some GM additive and 30 W syn engine oil is not good for diffy's....
I know that diffy's in FWD cars seem to run on ATF...so why not???
