48RE to 6 Speed Conversion

Im just gonna through this out there, im sure there is alreay a thread out there on this but anyways.....I got a buddy thats just sick of his auto and wants to through it off a cliff and go with the 6 speed, ive done like 6 other convrsions but none on a dodge. Im a duramax fan and owner at heart and a Power Stroke tech by trade. Im just wanted to make sure there wasnt something special about this conversion befor i went through with it. Oh ya his through is a 2005 2500 Crew Cab with the 48RE, Any tips.....

Put it this way, unless he has money to blow it is cheaper to build up his auto. Without a donor truck(another guy that wants to trade) then it is the upper end of $8000 if I remember right. With a donor truck it can be free. One thing to remember, the best chance of doing this is that both trucks need to be the exact same truck that rolled off the line with different trannys. Otherwise you will run into a whole lot of electrical BS.

I am in the process of talking to another member on here for a trade. I will post a thread with a lot of pics and how to's.

fyi you will change every wiring harness under the hood. it might would be better to buy another truck. but if you are saving money and don't mind the wrench time it may be worth it

Yes that can be the case. I have heard of people that have done it without trading all the harness'. Thats why I said do it with the exact same year only, otherwise you will run into a lot of problems. Not enough people have done this though to call it "fact" just yet. So keep in mind even if you do it with the same year, expect a lot of problems.
