ABSTRACT:
An assistor for operating a transmission, to be installed between the gearshift lever and the shift lever for actuating the shift jaws of the transmission, comprises a semicylindrical cylinder, a vane type piston adapted to turn slidingly within the cylinder, and a directional control valve for supplying a fluid to chambers defined by the vane of the piston. Operation of the gearshift lever opens the directional control valve to supply the fluid to one of the chambers separated by the piston vane, whereby the piston is turned and its turning output is transmitted from its boss to the shift lever.
