  • Control system and method for transmission clutch control
    Patent number: 8972131
    Abstract: A control system for a transmission includes an actuator module, a timer module, and a pulse module. The actuator module engages N hydraulic clutches and disengages M hydraulic clutches to operate the transmission in a gear ratio, wherein N and M are integers greater than zero. The timer module determines a first period starting when the transmission begins operating in the gear ratio. The pulse module selectively supplies a pressure pulse to P of the M hydraulic clutches based on the first period, wherein P is an integer greater than zero. A method for controlling a transmission is also provided.
