2-Tronic — gear boxes for Peugeot cars

2-Tronic is a 5-speed automated transmission installed on some Peugeot cars since 2005. It features a manual control mode and can adapt to individual driving style.

Operating principle

The 2-Tronic transmission is based on a manual gearbox equipped with two electromechanical devices controlled by a computer. One of them is responsible for gear selection, and the second one for engaging and disengaging the clutch. In order to switch to the manual mode, the driver slides the gear lever into the “M” position and then moves it to “+” or “-” to upshift or downshift. In this mode, the transmission can also be controlled with the help of paddle shifters.
