I just bought a 4 speed tranny that was on a 60. Can I attach it to a 3 speed transfer case or do I need a split case. I have a 72-40 with original f engine and drivetrain. I have looked at the tech stuff but I am a very GREEN mechanic and I did not know if a 60 4 speed would be different than a 40. I also do not know the year of the tranny. On the plus side I only paid 100 bucks.
