Abstract
A plurality of pins couple the cones and the shift collar of a transmission auxiliary section together so that they rotate as a group. When the shift collar is moved laterally from neutral, the shift collar engages blocking surfaces on the pins and moves the corresponding cone to match the speeds of the input shaft and the corresponding gear. The invention shortens the pin lengths of the synchronizer and therefore the length of the transmission, by eliminating contact between the shift collar and the small diameters of the pins in the neutral position.
