摘要： A method of adjusting a pressure signal to an actuator piston to control movement of a synchronizer actuator fork of a transmission includes moving the synchronizer actuator fork from a start position into a target position by applying an initial fluid pressure value. The time required to move the synchronizer actuator fork is measured to define a measured actuation time, and compared to a target actuation time. A correction factor is applied to the initial fluid pressure value to define a revised fluid pressure value when the measured actuation time is not within a pre-defined time range of the target actuation time. When the measured actuation time is greater than the pre-defined time range of the target actuation time, the initial fluid pressure value is increased. When the measured actuation time is less than the pre-defined time range of the target actuation time, the initial fluid pressure value is decreased.
