Hello everyone. I'm a diesel newb. I wish to swap a cummins 6 or 4 into my 1977 dodge sportsman rv. I'm working at a shop and was given an allison 545 trans and the supposed right adapter to mount to a cummins. Was told there a guy with a 4bt around as well. At the time i didn't know which Allison I was receiving. Looks like the 1000s + are the desired type. Is it worth using this transmission and can anyone identify the parts I have? I have a good 727a with a small block in there now, wonder if I can or should stick with that. I would prefer the easiest swap that offers the best mileage if possible. I know the 545 is a 4 spd with now OD. Is there a manual trans that would be simpler?
