Manumatic most often refers to an automatic gearbox; with some elements of manual transmission control (e.g. a gear can be manually selected instead of having the computer control all shifts). This type of transmission was introduced in the beginning of the 21st century.

Gearbox operation

Just like that of a manual gearbox, the automatic gearbox's primary job is to allow the engine to operate in its narrow range of speeds while providing a wide range of output speeds.

Without a gearbox, cars would be limited to one gear ratio, and that ratio would have to be selected to allow the car to travel at the desired top speed. If you wanted a top speed of 80 mph, then the gear ratio would be similar to third gear in most manual gearbox cars.

You've probably never tried driving a manual gearbox car using only third gear. If you did, you'd quickly find out that you had almost no acceleration when starting out, and at high speeds, the engine would be screaming along near the red-line. A car like this would wear out very quickly and would be nearly undriveable.

The key difference between a manual and an automatic gearbox is that the manual gearbox locks and unlocks different sets of gears to the output shaft to achieve the various gear ratios, while in an automatic gearbox; the same set of gears produces all of the different gear ratios. The planetary gear set is the device that makes this possible in an automatic gearbox.

The modern gearbox is by far, the most complicated mechanical component in today's automobile. Imake model) gearboxes contain mechanical systems, hydraulic systems, electrical systems and computer controls, all working together in perfect harmony which goes virtually unnoticed until there is a problem.

On a rear wheel drive car, power flow on a rear wheel drive the gearbox is usually mounted to the back of the engine and is located under the hump in the centre of the floorboard alongside the gas pedal position. A drive shaft connects the rear of the gearbox to the final drive which is located in the rear axle and is used to send power to the rear wheels. Power flow on this system is simple and straight forward going from the engine, through the torque converter, then through the gearbox and drive shaft until it reaches the final drive where it is split and sent to the two rear wheels.
