Abstract
A hydromechanical transmission shifting control system and method includes a hydromechanical transmission and a number of clutches connected to the transmission. A microcontroller receives various signals generated by the operator, engine, transmission, and the load. The microcontroller controls the ratio of the input to output speed of the transmission as well as the engagement or disengagement of the number of clutches based upon the various input signals.
