ABSTRACT:
A power transmission control system includes a single selector valve for setting three speed ratios and neutral position disposed between a fluid pressure source and three selectively engageable fluid pressure operated clutches for obtaining three speed ratios. The selector valve prevents fluid communication between the fluid pressure source and each three clutches and permits draining of the fluid pressure within each of the three clutches when in the neutral condition thereof. The selector valve permits the communication between the fluid pressure source and a selected clutch corresponding to the driving speed ratio selected thereby and prevents the communication between the fluid pressure and the non-selected clutches and permits draining of the fluid pressure from the non-selected clutches when in the one selected position.
