Claim:
1. A method for shifting gear ratios of a transmission system comprising: providing a first floating gear rotationally mounted upon a first shaft and a floating gear activation system for controlling torque transfer between the first floating gear and the first shaft, the gear activation system comprising a first device having a friction interface for frictional engagement with a friction interface disposed on a first side of the first floating gear, and a second device having a locking interface for interpositional engagement with a locking interface disposed on a second side of the first floating gear, the second side opposing the first side; providing a second floating gear rotationally mounted upon the first shaft and the gear activation system comprising a third device having a friction interface for frictional engagement with a friction interface disposed on a first side of the second floating gear, and a fourth device having a locking interface for interpositional engagement with a locking interface disposed on a second side of the second floating gear, the second side opposing the first side; engaging the friction interface of the first device with the friction interface of the first floating gear by sliding the first device along the first shaft; disengaging the locking interface of the second device from the locking interface of the first floating gear by sliding the second device along the first shaft; engaging the friction interface of the third device with the friction interface of the second floating gear by sliding the third device along the first shaft; disengaging the friction interface of the first device with the friction interface of the first floating gear by sliding the first device along the first shaft; engaging the locking interface of the fourth device with the locking interface of the second floating gear by sliding the fourth device along the first shaft; disengaging the friction interface of the third device with the friction interface of the second floating gear by sliding the third device along the first shaft; and shifting a transmission of torque from the first floating gear to the second floating gear without interrupting a delivery of torque through the transmission system.
