This removes the need for a physical clutch pedal. Most manual transmissions for cars allow the driver to select any gear ratio at any time, for example shifting from 2nd to 4th gear, or 5th to 3rd gear. The design of most manual transmissions for cars is that gear ratios are selected by locking selected gear pairs to the output shaft inside the transmission. Contemporary manual transmissions for cars typically use five or six forward gears ratios and one reverse gear, however, transmissions with between two and seven gears have been produced at times. This claim needs references to reliable sources. Operating such transmissions often uses the same pattern of shifter movement with a single or multiple switches to engage the next sequence of gears. Western Europe were equipped with manual transmission, versus 16. A manual transmission has several shafts with various gears and other components attached to them. This allows for a narrower transmission since the length of each countershaft is halved compared with one that contains four gears and two shifters. For reverse gear, an idler gear is used to reverse the direction in which the output shaft rotates. Independent rotation of the input and output shafts is made possibly by one shaft being located inside the hollow bore of the other shaft, with a bearing located between the two shafts. The input shaft runs the whole length of the gearbox, and there is no separate input pinion. This means the output shaft rotates at the same speed as the selected gear, thus determining the gear ratio of the transmission. The dog clutch is a sliding selector mechanism that sits around the output shaft. However, the clutch can move back and forth on the shaft, to either engage or disengage the splines. This movement is controlled by a selector fork that is linked to the gear lever. The fork does not rotate, so it is attached to a collar bearing on the selector. Once these speeds are equalized, the dog clutch can engage, and thus the new gear is now in use. In a modern gearbox, the action of all of these components is so smooth and fast it is hardly noticed. The synchromesh system must also prevent the collar from bridging the locking rings while the speeds are still being synchronized. The synchro ring rotates slightly because of the frictional torque from the cone clutch. In this position, the dog clutch is prevented from engaging. Once the speeds are synchronized, friction on the blocker ring is relieved and the blocker ring twists slightly, bringing into alignment certain grooves or notches that allow the dog clutch to fall into the engagement. Mechanical wear of the synchronizer rings and sleeves can cause the synchromesh system to become ineffective over time. Larger differences in speed between the input shaft and the gear require higher friction forces from the synchromesh components, potentially increasing their wear rate. This means that moving the gearshift lever into reverse results in gears moving to mesh together. When reverse gear is selected, the idler gear is physically moved to mesh with the corresponding gears on the input and output shafts. To avoid grinding as the gears begin to the mesh, they need to be stationary. However, some vehicles do employ a synchromesh system for the reverse gear, thus preventing possible crunching if reverse gear is selected while the input shaft is still spinning. Most transmissions include a lockout mechanism to prevent reverse gear from being accidentally selected while the car is moving forwards. This can take the form of a collar underneath the gear knob which needs to be lifted or requiring extra force to push the gearshift lever into the plane of reverse gear. Vehicles with manual transmissions use a clutch to manage the linkage between the engine and the transmission, and decouple the transmission from the engine during gearshifts and when the vehicle is stationary. In most automobiles, the gear stick is located on the floor between the driver and front passenger, but some cars have a gear stick that is mounted to the steering column or center console. This was actuated either manually while in high gear by throwing a switch or pressing a button on the gearshift knob or on the steering column, or automatically by momentarily lifting the foot from the accelerator with the vehicle traveling above a certain road speed. When the crankshaft spins as a result of the energy generated by the rolling of the vehicle, the motor is cranked over. This simulates what the starter is intended for and operates in a similar way to crank handles on very old cars from the early 20th century, with the cranking motion being replaced by the pushing of the car. Recently, many automatic transmissions have included more gear ratios than their manual counterparts. Driving a vehicle with a manual transmission is more difficult than an automatic transmission for several reasons. Lastly, a car with an automatic transmission obviously does not require filexlib.
