Abstract
A vehicle transmission transmits torque from an engine to a drive axle and includes a power shift transmission and a reverser module. A control system and method automatically partially disengages the reverser module during a shift of the power shift transmission with nearly no effect upon the operating condition of the engine, so that a portion of the torque generated by the engine continues to be transmitted at all times to the drive axle.
