There are 3 types of transmissions for bus and coach: manual transmission; manual transmission with robotized gearbox and the automatic transmission, which is still not so expanded and used mainly for special purposes like city buses.

Valeo S.A.T. technology advantages for bus fleets and bus drivers
More powerful engines, longer ratios and new lifetime specifications have led to the development and introduction of more complex clutch designs such as Valeo S.A.T. (Self Adjusting Technology). S.A.T. is revolutionary Valeo technology that uses a self adjusting facing wear compensation device on the pressure plate, thus enhancing clutch life and improving pedal comfort. Valeo S.A.T has an integrated system in the pressure plate cover assembly, featuring in compact design and enabling easy and quick fit.
The TH Damper breakthrough is a direct result of Valeo's ongoing commitment to research and development in transmission systems, and like all Valeo clutches, the TH Damper is manufactured to Valeo's highest quality standards.
TH Damper is able to increase dampening performance by 40%, while transmitting engine torque up to 3,500 Nm. This dampening performance allows engine speed reduction by up to 200 RPM, translating into fuel savings of up to 2%.
Valeo’s TH Damper features five distinct characteristics that enable it to achieve these results:
- A bigger damper of 285mm allows torque up to 3,500 Nm, while reducing noise, vibration and harshness.
- Five larger springs increase vibration dampening and limitates angular stiffness by -30%
- A spring seat bed allows the spring to operate only in compression mode, avoiding torsion.
- Original Equipment quality friction materials ensure high thermal resistance and limits vibration.
- A pre-damper reduces gearbox noise at low revs.
Valeo TH Damper with Valeo part 827561 and 827569 is fitted for example at Scania Coach .
