Abstract

This invention pertains to transmission testers, and specifically to automatic transmission testers, and methods for their use. The headstock is mounted for pivotation about a vertical axis. A novel eddy current brake provides active control of loading of the transmission while the transmission is being tested. The prime mover is preferably an electric motor, with motor controls, adapted to temporarily suspend acceleration of the speed when the transmission shifts gears.
