Abstract: A method is provided for operating a hydraulic control system for a transmission having first and second torque transmission paths arranged in parallel with one another between a common input shaft and a common output shaft, first and second hydraulically controlled clutches arranged in the first and second torque transmission paths, respectively, and a hydraulically controlled gear synchronizer in the second torque transmission path for selectively coupling a shaft for rotation with a gear wheel to effect a change in the transmission ratio through the second torque path while the second clutch is disengaged. To prevent wear on the synchronizer and the gear, prior to activating the hydraulic control for moving the synchronizer into engagement with the gear wheel, the hydraulic control system is operative first to move the synchronizer into a neutral position in which torque cannot be transmitted through the first torque transmission path.
