Abstract

An interlock device for a shift mechanism of a multi-speed power transmission device includes a shift rod capable of selective axial positioning at a plurality of predetermined locations for specific gear ratio operating conditions and a neutral non-operating condition. The shift rod includes detents in the surface thereof associated with these locations and a position locating device is aligned with the shift rod to be capable of being forced into engaging contact with one of these detents by the introduction of pressurized air into a power cylinder acting thereon. Selective axial positioning of the shift rod is prevented when the torque transmitting power source providing the input to the transmission device is in a power mode and causes the pressurized air to be applied to the power cylinder.
