i bet ya can't wait.i read a vette mechanics opinion (well known)he said there is nothing wrong with the G.M. brand,but some report noise or slight bindage.he said this could be due to the limited slip additve and the G.M. fluid seperating when the car sits over night,you get up the next day and drive,but it takes a few miles for the two fluids to mix thru the differential.over time this is wear.i don't know if this was ever provin.
i use red-line.has the additive,but its particals don't seperate.i have had it in there for one year with no problems,actually the rear end felt smoother immediatly after changing.i have put many 1/4 mile runs on the car,and will change it soon (about every 18 months).just my opinion/experience.not trying to sway you either way......:smokin:
