Howdy guys,
I finally bought a rebuilt 3.03 today, never used. It came out of a 72 mustang with a 351. It looks exactly like the one i took out of the car. Im not sure if i have to break it in or how to do so though. He got it rebuilt 7 years ago, but then decided to put in a 4 speed, so its never been used like i said earlier.
So how do i break it in? And what kind of gear fluid should i use? I use 90w in the rear and previously in the old 3.03, is that the one i should be using?
Thanks guys!
Ryan
