Got the 3 speed tranny out of the shop a few days ago and I am fixing to install it this weekend.
Guys, I was wondering what kind of oil should I use for the tranny?
It's a half ton 1953 Chevrolet truck with an enclosed driveshaft.
Is SAE 140 too heavy? Should I use SAE 80W-90?
While I am at it, what about the gear oil for the rear end? Same as the tranny?
Thanks in advance.
