ABSTRACT:
An automatic transmission brake adapter for use in high performance vehicle drag racing. In electronic controlled automatic transmission, the transmission is held in both reverse and drive allowing the engine to accelerate without movement of a vehicle. Release of the reverse gear and associated rapid acceleration of the vehicle in drive is accomplished by a modular transmission brake adapter using the existing electronic automatic transmission control system without extensive modification thereto.
