Governor Assembly

The governor assembly, see image, regulates a speed sensitive oil pressure that increases with output shaft or vehicle speed. Governor-pressure is used to vary the shift points and modulator pressure.

The vehicle speed signal to the modulator valve is supplied by the transmission governor, which is driven by the output shaft. The governor consists of two sets of flyweights, two springs and a regulator valve. Centrifugal force of the flyweights is imposed on the regulator valve, causing it to regulate a pressure signal that increases with increasing speed.
