ok i got a 91 v6 4wd ext cab dakota and it runs great but the trans is fu@#ed it has 1,4,5 and rev and i cant find a nv435 so i was woundering if i can put a nv2500 or a ax15 and what would be involved in doing this?

drag racers know where the finish line is....they don't have to drive around in circles looking for it !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
