Active Select: features, advantages & disadvantages

Active Select is a system of manual gear shifting in automatic transmissions for Opel, Holden, and Vauxhall vehicles. It was released in the early 2000s. The manual mode enhances the vehicle’s dynamic characteristics. For instance, it ensures a more reliable start on slippery surfaces, and improves manoeuvrability. It is essential for gaining speed as it allows for faster acceleration.

How it works

The Active Select system is available on classic transmissions equipped with a hydraulic torque converter, planetary gear sets, and electronic control. In automatic mode this transmission can adapt to individual driving styles. For example, if a driver prefers a sporty style, gears will be shifted at higher RPMs. To activate the manual mode, the driver slides the gear lever from the “D” position to the left, then briefly moves it to the “+” or “-” position to shift gears up or down. The selected mode and gear are indicated on the dashboard.
