Redline 75W90 for differential question - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I want to change the fluid in my differential and I think I want to go with Redline 75W90. It says it doesnt need any additional friction modifier added but I want to know from those that have used this if they needed any or not?

I would stick with the factory stuff with the factory diff

I used it no friction modifier no noise no issues 18000 mile on my vert
12000 on my silvy

Used it here fine no problems. Seems smoother.

No problems and no additional additives for 10,000 miles. Put it in at 500 miles when I did gear swap to AAM 3.91s. Very quiet, no noise at all.

Also use Redline D4 ATF in my M6. Had 2nd gear grinding issues from the beginning until trans would warm up. Tried all the others (GM, Mobile1, Royal Purple). Redline made the most difference especially when trans temp was < 180*.

Funny you mention that because I'm changing over to the D4 in my M6 for that exact reason. I figured once the car was up in the air I'd do the differential at the same time.
