Beschreibung
Zusammenfassung:	A motor vehicle drive train device includes a multi-group transmission with a main group providing at least one forward transmission gear and at least one reverse transmission gear, and a downstream group downstream from the main group. The device also includes a control and/or regulation unit having a gear change function for shifting the main group at least in one transmission gear change operation in order to engage a transmission gear opposite to the current direction of travel. The control and/or regulation unit has a synchronization function which is provided for shifting the downstream group in order to engage the transmission gear opposite to the current direction of travel.
