Manual transmission is also known as 'shift transmission.' The manual gear lever acts as a shift fork, moving the sliding gears inside the gearbox to engage the corresponding gear, thereby meshing the driving and driven gears to transmit power and drive the vehicle. Hence, it is called 'shift transmission.' Its working principle involves shifting the gear lever to switch the driving gears on the countershaft, combining with the power output shaft through different gear sizes to alter the torque and speed of the driving wheels. Manual transmissions also include additional gears like 2 and 1 for starting or climbing slopes. When the clutch is depressed to shift into a new gear, the synchronizer aligns the speeds of the two gears to be meshed inside the transmission, ensuring smooth engagement. After releasing the clutch and easing off the accelerator, the engine speed naturally decreases accordingly.
