Since the popularization of the [[hydraulic automatic transmission]] in the 1940s, many automatic transmissions have allowed indirect control of the gear selection, usually in the form of locking out higher gears. This was provided to allow engine braking on downhills or prevent the use of [[overdrive (mechanics)|overdrive]] gears when towing and was typically achieved using positions such as "3", "2", and "1" on the gear selector.

An automatic transmission with a ''manumatic'' function provides a greater level of control by allowing the driver to request an upshift or downshift at a specific time. This is usually achieved using "+" and "-" positions on the gear selector or with paddle-shifters mounted beside the steering wheel. On modern gear selectors with "+" and "-" positions, the positions are on a connected longitudinal gate to the left or right of the standard gear positions. Several Chrysler and Mercedes-Benz vehicles from the 2000s have horizontal gates at the bottom of the shifter pattern. Manufacturers use a variety of tradenames for the manumatic function, as listed below.

The driver often does not have full control of the gear selection, as most manumatic modes will deny a gear change request that would result in the engine stalling (from too few [[RPM]]) or over-revving. Some transmissions will hold the requested gear indefinitely, while others will return to automatic gear selection after a period of time.
