  • Patent number: 8225695
    Abstract: An arrangement for inhibiting axial movement of a range clutch in a transmission includes a driver adapted to move the range clutch axially on an output shaft between a high range position and a low range position, a sensor arrangement adapted to sense at least one of reverse rotational direction and potential reverse rotational direction of at least one of a main shaft and the output shaft and to generate an inhibit range shift signal upon sensing at least one of reverse rotational direction and potential reverse rotational direction, and a controller adapted to inhibit operation of the driver upon receipt of the inhibit range shift signal from the sensor arrangement. A transmission and a vehicle including such an arrangement are also disclosed. A method for inhibiting axial movement of a range clutch in a transmission, and a method of retrofitting a transmission with an arrangement for inhibiting axial movement of a range clutch are also disclosed.
