摘要:
A synchronizer actuating system with selectives for use in dual clutch transmission is provided. The synchronizer actuating system includes an apply finger and a fork mounted on a shift rail. The fork grips a synchronizer sleeve that supports a synchronizer. The synchronizer is moveable to a neutral position. A three area piston assembly is operable to engage and actuate the apply finger. The three area piston assembly includes a hydraulic neutral position. A selective element is coupled to the synchronizer actuating system to calibrate the hydraulic neutral position of the three area piston assembly to the neutral position of the synchronizer sleeve.
