Abstract:
1. A method of operating a dual clutch transmission, the method comprising: sensing a deceleration rate of a first shaft, with a transmission control module, when a synchronizer is positioned in a neutral position to define a first rate of deceleration; moving the synchronizer along the first shaft from the neutral position toward a gear with a synchronizer actuator fork; sensing a deceleration rate of the first shaft, with the transmission control module, while the synchronizer actuator fork moves the synchronizer along the first shaft to identify a change from the first rate of deceleration to a second rate of deceleration; and identifying a location, with the transmission control module, of the synchronizer actuator fork relative to the first shaft at which the rate of deceleration of the first shaft changes from the first rate of deceleration to the second rate of deceleration as a synchronous position of the synchronizer actuator fork.
