This is for a 88T2 -
I know you guys want 75w90 in your diff, but im going to change all my fluids tom and I dont think they carry redline at normal parts stores.

So first off where can I get Redline oil at, if any normal parts store? Napa, autozone, checker, walmart?

If I cannot get it at any store what should I use instead? Just get synthetic oil of the same viscosity?

Also what viscosity and brand(if no one carrys redline) of tranny fluid(along with the diff if different from what i said)?

 

go to a mobil 1 they will have the tranny/diff fluid indefinately but on the oil part you will need to go to a tune shop or maybe a pepboys that will have redline. i believe i saw royal purple and redline at pepboys a 3 days ago

 

Advance Auto carries Redline

 

I have no problem running mobil 1. Ran it in the past and loved it. So 70w90 is correct for the clutch type rear diff right?

Then what viscosity should I use for the tranny fluid?

Ill search for some redline first since iv read tons of posts on here about people loving it, but if not ill go with the mobil 1.

thanks guys
