None of the 727/618/47RH series have a mechanical OD. The 47RH has TCC and OD, but both are electrical. That transmission came in the 94-95 year models. The rest of the transmission is hydraulically controlled via govenor housing.
If your current trans has lock up TC then it all should interchange. Ofcourse driveshaft changes.Thanks again,
Are you aware of any fitment problems? The truck has the Cummins adapter for the 3-speed. I suspect I will have to use another driveshaft or shorten the one I have. What about the torque converter and pilot shaft?
Whoa! For that price he could buy and build himself a nice 47RH.gearvenders makes a od that goes on the back of your current trans they are 2500-3000 bucks if i remember right.there was one for sale on here not to long ago you might look back in the forsale section and see if its still there.
No you want one from a diesel. The govenor weights , VB ,and internals are different.I had a thought. Since I will be engaging the OD with a manual switch, could I use a transmission from a gas model, like a V10 or 360?
