I am getting ready to start my project truck Cummins swap, getting the 12 valve mounted and running is not a major worry of mine, my worry is that since my plan is to use the dodge auto and transfer case (47RH/NV241DLD) at least at first (Almost completely because funds are a little low to be buying a $1200 adapter setup to go to a c6 or a sm435 with a 205 and that the dodge tranny is very fresh from a strong rebuild), my worry is getting the tranny to shift and operate properly, with a functional overdrive and torque converter lock up, the donor truck was a rollover so i have the complete wiring harness with the gauge pod, steering column and the computer. Would my best option be to go with a manual valve body, I would be fine with that but i cant find one? or will it be possible to run what i have? Any Advice is much appreciated, Thanks!

P.S. i have spoke with fordcummins.com on this issue and they have no insight-

Truck specs: 1975 Ford F250 Highboy, standard cab long bed, dana 60 high pinion front, sterling 10.25 rear (4.10's), painless wiring harness, fresh paint, 38" PJ dirt grips on mickey Thompson super singles, and soon a 12 valve cummins!

 

you should be able to use the dodge transmission. when you wire it though your going to have to make sure all of your sensors are hooked up to the computer and working. the computer will be what controls your shift points and transmission controls. its all going to be electrical things that make it work. i would recommend using the stock dodge wiring harness for all of the engine tranny, and just splice in to make the gauges work

 

A bud of mine installed a 12v into a 56 ford. he used the 47rh trans and only needed to put two toggle switches for od and torque converter lockup. switches are on the ground side of the circuit. I think he found a wiring diagram online. I have riden in his truck and the switchs work like they are spose to.

 

Not sure about the lockup, since my A518 doesn't have it, but this is how I wired up my OD and it works very nicely.
