The training discusses the design, operation and structure of data transmission in automated gearboxes, on the example of the popular ZF AS-Tronic 12-speed gearbox used in some trucks. We discuss the replacement of clutch discs in MAN, DAF and Renault vehicles equipped with the AS-Tronic gearbox, the stroke and the thickness of the disc programmed in the gearbox controller. After installing a new disc, which will not have the parameters saved in the controller, it may turn out that the car will not leave the workshop. And even if it does, the gearbox can go from automatic mode to emergency mode. Discussion of common mistakes made by workshops that practice disassembling and assembling the gearbox. Selection of clutch and parts depending on the configuration of the vehicle. For example, a vehicle equipped with a power take-off that lasts more than half an hour has a clutch disc with a reinforced vibration damper. Important information when selecting and replacing gearbox parts.
