gear oil for break in??

what gear oil should you use to break in the tranny I am using 85W-90 in the car right now, is this okay, haven't started it yet, going to swap it out for some redline synthetic later.

Make sure it is GL-4 and not GL-5 then it would be OK. When you switch to Redline go with the ShockProof gear oil.
