A transmission gear synchronizer apparatus includes first and second friction races mounted for movement coaxially with each other in a spaced apart relationship, with the friction races being mounted for coaxial movement into and out of engagement with friction surfaces. An annular shiftable clutch collaris positioned between the two friction races, with the clutch collar being mounted for coaxial movement with respect to the friction races to enable engagement of the clutch collar with transmission gears, the clutch collar having at least one orifice through which a pin can be extended. A first pin extends through the clutch collar orifice, and is secured at one end to the first friction race, with the other, distal end of the first pin extending toward the second friction race, where alignment of the first pin within the clutch collar orifice is required to enable the clutch collar to move axially with respect to the friction races. A spring biases the first pin out of alignment with the clutch collar orifice so that alignment of the first pin within the clutch collar orifice requires force to overcome the bias of the spring, where one end of the spring is connected to thedistal end of the pin and the other end of the spring is connected to the secondfriction race.
