![]() Manual transmission cars are as old as the motorcar itself, but does that mean a manual transmission is better than an automatic? Here are some advantages and disadvantages to a stick-shift setup: The friction clutch is a lossless, direct drive to the wheels. To prevent the crunching associated with gear changes on old-style unsynchronized gearboxes, synchronization rings or cones are used. Most modern manual transmissions are of the constant-mesh type, with the shift lever operated by the driver connected to shift forks that move around dog clutches to engage the different ratios. While this may mean some manuals don't feel as smooth or swift in between each shift, many enthusiasts prefer the option to be in charge of gear selection. This causes a momentary pause in acceleration, which some feel is reason enough to believe an automatic transmission is better than a manual gearbox. Here, the driver must manually move a lever through an H-gate to select the gear they want while depressing a pedal that operates a single clutch to disconnect and reconnect the drive. The standard manual stick-shift transmission is the least popular of all car transmission types available in the US, and leaves all the work to the driver. So, how do the different types work, and if you have to choose between manual vs automatic transmission, which is best? ![]() Any transmission connected to an internal-combustion engine, whether a manual or an automatic, works on this basic premise. The higher gear ratios result in far less wheel torque, but gives the vehicle the "legs" for economical cruising on the highway - more speed. The lower gear ratios provide plenty of wheel torque to climb steep grades and do hard work - simply put, more power, but less speed. Some transmissions have an infinite number of gears, which you'll read more about below. Depending on the transmission, there can be any number of gears: as few as five and as many as ten. Manually selecting the desired gear requires depressing a clutch pedal to disengage the connection between the engine and the wheels in order to change gears. This torque is sent to the wheels using the appropriate gear ratio, which is selected either manually, or automatically. ![]() ![]() It is a crucial part of the drivetrain that transmits torque to the wheels via the differential, which splits the power between the wheels and is, in turn, connected to the driveshafts and wheels. In terms of a definition, a transmission is the link between the engine in your vehicle and the wheels. And, while there is much more to it than simply that, understanding what a transmission is will help to make these distinctions a little easier. If you are under the impression that there are only two types of transmission for a car - namely a manual and automatic transmission - you aren't alone. ![]()
