	Drivetrain Design and Development Section of Southwest Research Institute

Since 1990, the transmission test and evaluation services and capabilities for transmission efficiency and development testing and evaluation systems have been aggressively developed at Southwest Research Institute (SwRI).

To date, SwRI has evaluated transmissions ranging in size from 1.6- to 8.0-L engine applications and produced by manufacturers from around the world. SwRI has developed an extensive database of transmission efficiency data.
