Easytronic

Easytronic is the Opel tradename for a type of transaxle-based semi-automatic transmission or gearbox, as used in some Opel/Vauxhall cars.

Easytronic is not a tiptronic gearbox design; it does not have a torque converter. It is fundamentally a conventional manual transmission, with a single-plate dry clutch. The transmission is controlled by an electronic control unit (ECU).

The Easytronic is generally used in smaller modern front-wheel drive cars, including the Corsa 1.0 & 1.2 & 1.3D, Tigra 1.4 90 ps, Meriva 1.6 & 1.8, Astra 1.4 & 1.6, Zafira 1.8 140 ps and Vectra/Signum 1.8 140 ps.

The Easytronic transmission is manufactured for Adam Opel AG by ZF Friedrichshafen AG.[1]

This system combines a clutch actuator, a gear selector and a clutch. Imagine the gear selector is your left hand and the clutch actuator is your left foot. With the clutch fitted in the usual place between the engine and gearbox all that is happening is that the car engages gear according to the speed of the vehicle via the clutch actuator while the gear selector simply selects correct gear. The clutch actuator works on hydraulic fluid which is operated via a master cylinder which is built in. The gear selector is composed of two motors: a select and a shift. Easytronic transmission combines all the ease of an automatic with the control of a five-speed manual gearbox. Set to manual mode the Easytronic changes gear simply by moving the lever forwards or backwards, while automatic mode is just that, complete with kickdown.
