I am considering a 4 speed Saginaw tranny, mainly cuz my 3 in the tree freezes up going into 2nd( at least TRYING to go into 2nd) it wont go into gear. it's a 54 3100 panel truck with the 235-6. Is getting a Saginaw worth the expence, are they pretty dependable? sorry for the "rookie" question but that's what I am .Thank you. John Deurr
