Gear selectors and selector forks
The gear selector piston is connected to the selector
fork. To change gears, oil pressure is applied to the
gear selector piston, thereby moving it. When it
moves, it also moves the selector fork and the sliding
sleeve. The sliding sleeve actuates the synchronising
hub and the gear is engaged.
