Local Autozone has it on sale. Anybody use it, or have used it? Gonna change my tranny soon and was wondering if I should try it.

 

I use the 75W-140 full syn in mine.

 

I just changed the trans fluid on mine and used the HD branded 80W-140 synthetic. No problems yet but, I've only put a few hunnert miles on it.No weird noises or shifting problems. Guess I'll find out how it holds up next week when I go to Maggie Valley on vacation.

I just put Valvoline full syn 75w140 I think it was. Seems just fine. No problems. Very little difference from whatever 20w50 was in it.
