We design the Allison 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.

The chart below shows the K factor and torque ratios as related to our converter stalls. Below is how to interpret the K factor and torque ratio numbers. The lower the K factor, the better the converter will couple. The higher the K factor, the easier the converter will spool up. The torque ratio is the torque multiplication number. For example, if a converter has a torque ratio of 1.85, then for every 100 lbs of input torque, the converter will deliver 185 lbs of output torque. This is at a converter stall or speed ratio of 0. This ratio will go down as the speed ratio goes up. Engine modifications will directly affect stall speed. Stall speeds listed below are approximate & will vary based on engine torque.
