Mercedes-Benz Automatic Transmission 722.9 Technical Training Materials
Transmission Application
- 722.9 transmission will be offered in the future:
– as an option in new SLK (R171 – 09/04)
– standard equipment for new M Class (W164 – 2005)
– standard equipment for new R Class (W251 – 2005)
– standard equipment for new G Class (X164 – 2006)
– standard equipment on CLS 350 / 500 (late 2004)
– standard equipment on E350 (late 2004) - 722.9 for W164 / W251 / X164 will be equipped with shift by wire (no shift rod). Instead an electric control module is fitted to operate shift control valve and monitor position via a positioningsensor.
- End of production or outgoing models are unlikely to receive the 722.9 transmission (W163, R170, V463)
