text: A618/47RH-RE for heavy-duty use behind the V10 gasoline and Cummins diesel engines. The 47RH was used in the 1994 and 1995 model years, while the 47RE was used from 1996 through 2002. The 47RH was released first and was only used in the Ram 2500 and 3500 series trucks. The transmission was able to produce 450 lb-ft of torque and was able to tow trailers up to 19,000 pounds. This transmission was rated to be the highest capacity in the one-ton series of trucks produced by any manufacturer. The RH was a hydraulically operated 3-speed transmission with a hydraulically controlled overdrive gear. The RH was later replaced by the RE however it was by name only since they are both hydraulically controlled.
  The NV3500 was offered in 1500 and light-duty 2500 trucks. The NV4500 was standard in heavy-duty 2500 and 3500 trucks; the NV4500HD for V10 and diesel models. An NV5600 was offered in 1999 and 2000 Rams and was the only transmission offered behind the High Output diesel in 2001 and 2002.
