So I am just getting parts gathered for my swap. I have a 94 GMC 3500 6.5 diesel that I am putting a 24 valve out of a 2000 dodge truck. I was going to use my 4L80E, but I have decided not to so now I am deciding between a 47rh or a 47re. They both should bolt right to the cummins but some people I have talked to say I will need to use the 47re cause it is partly electronic so I can buy a controller to change shift point and such which is why these people say the 47rh wont work very well is cause I cant change shift options. So which transmission is better for my application?

Go to destroked.com they have alot of different parts for doing Cummins conversions. Motor mounts,trans controllers, adapter plates. You may even choose to use the 4L80E in the set up

Ya I have been there and talked to them and talked to autoworld repowers. By the time I spend over 2000 dollars to keep my bone stock tranny, that the cummins will tear up any way I could spend the money on a 47rh or re and have a pretty well built tranny to go behind the cummins. I am just wondering which one the re or rh would work better?

So I am leaning toward a 47rh, does anyone have anything good bad or indifferent about it?

fed ex gets an allison 545 behind there 5.9 cummings. it isnt over drive but has a low first.

Both are made to run behind your Cummins; not a great need to adjust shift points unless you just want the option. I ran these options when I decided to put an automatic in my Cummins truck. The RE and controller from Suncoast can be made to work in your truck. It just gets wired into the VSS signal. The RE does use a TCM, IIRC.

So if I do the RH then there wouldn't be much need to adjust shift points then? Did you run either of these trannys if so which did you like better? Thanks

The only thing you can do, without a full build, is change solenoids on the RH. I weighed my options and opted to go with the Allison 1000. I'm not a fan of the 47 personally. I did talk to a lot of people and asked a ton of questions. The resounding answer was the 48RE, to be honest.

Bare in mind, I was never recommended a stock transmission of any model.

If you are not building a monster you can probably get by with a stock 47RH or RE for quite a while.

Hopefully someone with some Dodge transmission knowledge will chime in. I can also ask some of the 12 valve guys what they did with theirs.

The RH will require adjustments to the governor assembly to make shift point changes. You can make small changes via the throttle cable, but this will raise them across the board. The RE is electronic and can be adjusted via a laptop. On the RH there are only 2 solonoids in it, lock-up and OD. They can be cudely controlled via 2 pressure switches and a microswitch(the vacuum switch in the write-up obviously won't work for a diesel) to act as a WOT switch. http://www.transmissioncenter.net/SwapInformation.htm Most all of the 48RE improvements can be applied to a 47RE from what I've read, the people at GOERANDS can answer all your questions and help you with a killer build for a DODGE tranny.
