I just finished rebuilding my gsr motor that I baught a while back and took it for a drive and my buddy said i might not have gotten a gsr tranny with it. What marks or numbers can I look for on the tranny to tell what tranny it is?
Thanks HT

In 5th gear it should take just under 3.5 turns of the crank to get 1 turn of the wheels/diff.
