Running a special on heavy duty built cummins 48RE 47RE 518/618 transmissions with a new billet torque converter. These are built to handle high horsepower/torque cummins engines. As long as you have a great aftermarket cooler system this transmission will last a very very long time. Dodge cooler systems are a major problem for the transmissions. If you pull daily or have a programmer this is the transmission you want for half the cost of the big name brand companies who overcharge for the same build. Heres a list of what's in side.
