A Tiptronic transmission can function as an automatic transmission or a manual transmission depending on which setting has been selected. Tiptronic devices often have special performance settings to give the driver more control over a vehicles performance and make automatic mode feel more like a sports car.
Tiptronic manual shifting is controlled through buttons with a plus sign for up-shifting and a minus sign for down-shifting. This is similar to what many sports cars use in order to give an authentic feel. The first Tiptronic system was originally produced by Porsche; since then, later systems adopted similar technology with the same name.
Tiptronic systems allow drivers to choose whether they want to drive automatic, where the computer does gear shifting or manual mode where the driver has the opportunity to change the gear. Other systems have tried to emulate the feel of manual without giving you full control, but the Tiptronic transmission is the first device that offers a choice. The system has safeguards in place that keep drivers from going past the RPM red line when operating under manual control. If drivers fail to use manual shifting for a certain amount of time with Tiptronic, the software on the transmission automatically switches back to automatic and controls all shifts through the computer once again. It is then necessary to turn it on again to go back to manual.
