1LE diff fluid - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

About to install my 1LE diff. I got 2qts. of 75-90 from the dealership. It says the friction modifier is already added. This is the same fluid that is factory filled in the ZL1 and the fluid that is called for in the rear axle chatter TSB. Is this the proper fluid for this diff and how much do I use? The dealer is saying 1qt. which seems low.

I was told the fluid for the zl1 is the incorrect one. Not compatible withe the seals. I used gm oil and then added the gm additive. 1qt will fill it unless you spill some. Your owners manual will also say 1qt.
