Geartronic — gear boxes for Volvo cars

Geartronic is a manumatic gearbox with a hydraulic torque converter and a manual mode function, which is used on Volvo passenger and commercial vehicles. It was released in the 1990s. It is now available on almost all models of the make. The manual mode allows the driver to take control of the vehicle if necessary; for example to improve its off-road capability or dynamics in certain driving situations.

How Geartronic works

By default, the Geartronic operates as an automatic transmission, independently calculating and changing the gear ratio. In order to switch to manual, the driver slides the gear lever into the “+S-” slot and then to “+” or “-”, depending on the gear they want to shift to. Many modern Volvo models also have paddle shifters for manual transmission control. After switching to manual, the colour of the dashboard indicator “+S−” changes to orange, and a number appears to indicate which gear is engaged.
