We design the 47/48RE converter components here at Goerend Transmission, and also manufacture them from start to finish using our eight in-house CNC machines. This ensures accurate dimensions that work with your transmission. This also means you are communicating directly to the manufacturer, which is very rare in this industry, and allows us to answer all questions quickly and accurately. We build our billet front covers and clutch pistons from steel forgings, greatly reducing any chance of porosity. Our stators are designed to rotate better when going into coupling mode, as well as assist torque multiplication and are guaranteed to never break. Our patented internal design insures that the torque converter clutch will lock up on the computer and valve body’s signal. Our knowledge, equipment, and patented converter components allow us to build the converter to match your needs, no matter if you use it as a daily driver or a dedicated race truck.
Truck: 2004 early 305/555 Cummins.
Stock converter was always pretty poor, then I picked up a tuner and the weak link of the stock converter was a huge issue. I bought this lower stall 15ss and it transforms the behavior of the truck. Where it would previously wind out way past peak torque before sending any significant amount of power through, this lower stall converter transfers the power far earlier. It also transfers significantly more torque to the transmission when unlocked. When unlocked this results in a lower rpm for a given speed and a much more responsive throttle. It's the most transformative change of anything I've ever installed on a truck.
