TranstarSynchronizer Ring

A synchronizer adjustes the speed of the shaft so that the gears align more quickly as you shift. The slider pushes against the keys or balls in the synchronizer, which then push against the blocker ring. That ring then pushes against the gear's cone, and the friction it causes helps the shaft speeds to equalize.
