how manual transmissions work

How in depth do you want?
I drive stick. You have a clutch that connects the output shaft from the engine to the input shaft of the transmission. You disconnect the engine from the transmission when you disengage the clutch via a foot pedal, a piston presses on the diaphragm, releasing the pressure from the friction plate. From there, you’re able to select a gear via a shifting lever, or stick. This stick connects with a shifting fork that interacts with rods in the transmission to push/pull gears into a mesh (mesh is when the teeth of gears interlock).
There are of course speed differences between the gears, for this, most car transmissions have synchronizers to bring all the gears to the same relative speeds to make the shifting process easier. You *can* shift without the use of a clutch through what is called “floating”, but this requires very precise speed matching between your engine RPM, the speed you’re currently going, and the gear you wish to go into. This is a more common thing among trucker’s though, as the RPM ranges are much narrower making it easier to Rev match.
