Manumatic

Manumatic is a portmanteau of the words manual and automatic, that applies to a class of automotive transmissions.

Manumatic refers to an automatic transmission that allows convenient driver control of gear selection. For most of automotive history, automatic transmissions already allowed some control of gear selection using the console or column shifter. Manumatics enhanced this feature by providing either steering wheel mounted paddle shifters or a modified shift lever for more convenient operation. Different car manufacturers have been using a variety of labels for their manumatic transmissions, such as 'Tiptronic', 'Geartronic', 'Touchshift', 'Sporttronic', 'clutchless-manual' and others.

Some manumatic and semi-automatic transmissions allow the driver to have full control of gear selection, while many will intervene by shifting automatically at the low end and/or high end of the engine's operating range, depending on throttle position. Manumatics and most semi-automatic transmissions also provide the option of operating in the same manner as a conventional automatic transmission by allowing the transmission's computer to select gear changes.
