ok so i have a 94 cummins and it needs the tranny rebuilt the guy said just for the parts its gonna be 800 and well my question is how much would it cost me to put in a six speed i know there are people who have done this and i would really be helpful if someone could help me out

 

i had mine rebuilt by amco and it was 2800 to rebuild either get a built tranni like sun coast or 5 speen dont rebuild to stock
