ABSTRACT:
A hydraulic control for a power transmission has an electronically operated mode during normal operation. In the event of loss of electrical power, a power interrupt valve is operable in conjunction with a manual valve to direct fluid pressure to the proper devices as selected by the operator, thereby permitting operation to continue in a manual override mode.
