Im trying to find a tranny 5 speed for my cummins swap into my f350. I was going to do the 5600 but heard they wernt worth it to big and heavy. And still have number of problems. I was reading somewhere that someone had suggested a differnt. Tranny. With bigger fly wheel and stuff does anyone think of somthin. As of now im going with 4500

 

My dad has the 6 Speed in his '01 and I likes it a lot, its super nice! The NV4500, I have never had my hands on, I hear it just has different ratios and is just as nice.

 

both my cousins upgraded to the new venture 4500 they have identical 91.5 ctd's getrags are worthless and the 94 has a 4500 never had any problems haulin 25k two or three times a week for.... since i can remember just a new clutch once in a great while but ur not gonna go wrong with a new venture id bet my buddys left nut on that one, and uh hes a pretty good buddy.
