How a Manual Transmission Gearbox Works

This quick introduction into the world of Manual Transmission Gearboxes is from “Geeks On Cars”.

Manual Transmission Gearbox  Image converted using ifftoany

Manual-transmission gearboxes are the simplest types of gearboxes and involve the manual movement of a sliding gear along the gearbox’s main shaft using a shifter. The shifter is attached to a gear lever, which moves the sliding gear. When the driver engages the clutch, the sliding gear disengages from its existing position and can slide up and down the gearbox to re-engage in a higher or lower gear. Manual-transmission gearboxes contain a diagonal gear that sits beside the main gears and ensures that the sliding gear is synchronized with main gears. This synchronization allows the sliding gear to seamlessly engage with the main gears and prevents the gears from clashing with one another, which can damage the transmission. Modern gearboxes contain two sliding gears, one of which engages exclusively with the reverse main gear. This second sliding gear is constantly synchronized with the reverse main gear and allows the operator to seamlessly shift from forward to reverse.
