The transmission is one of the most expensive and complex systems of any car, it needs regular diagnostics and maintenance, therefore, at the first suspicion of a malfunction, it is recommended to contact the service center
So, the gearbox is:
- Variator, it is stepless.
Automatic transmissions appeared on cars after the war: the first serial Buick “on autopilot” was released in 1947. The principle of operation of an automatic transmission is notable for the fact that gear shifting occurs due to the interaction of planetary mechanisms and a hydromechanical drive using electronic actuators.
The robotic transmission is an evolutionary continuation of the development of the manual transmission. The robot, essentially, is a manual transmission in which the clutch release and gear shifting are performed by two servos controlled by an electronic unit. This type of box conventionally combined all the positive aspects of a manual transmission and the convenience of a machine.
The first prototype of a robotic box was created by Adolf Kegress in 1939. He thought of the dual-clutch transmission, but the further development of this promising invention stopped due to financial difficulties.
Volkswagen engineers ventured back to development and later serial production only in 2003, having installed a preselective transmission on the sports version of the Golf model. Until now, the VAG corporate group is actively promoting this type of boxes of its models.
