Automatic racing transmissions operate in much different conditions than their street driven relatives. Racing units are designed and built to have much firmer shifts via high hydraulic pressure, the gears and shafts are made from steel developed by the military and space industries and the valve bodies are reconfigured to allow transbrake or second gear launches.
The minimum requirements for today's high power race engines means that very few of the original OEM components are used in a modern racing transmission. In fact, our Top Sportsman powerglide transmission uses no OEM components - from the input shaft to the output shaft, every major component is new and designed entirely for drag racing usage.
BTE is unique among racing transmission building organizations because of our ability to manufacture our own primary components. After a weekend at the racetrack, we can prototype, test, and manufacture starting the following Monday.
This week, we will look at some of the ways we develop new transmission improvements and how they are implemented into the racing transmissions we build every day.
