A drive system is described for a vehicle having a first and a second set of wheels comprising: an engine; a transmission connected to the engine adapted to produce a range of drive ratios; a rotatably mounted driving member having a first clutch surface connected to the transmission output and continuously driveable connected to the first set of wheels; a rotatably mounted driven member having a second clutch surface; and lockup means moveable to an engagement position where the driving member and driven member are driveably connectable and moveable to a disengagement position where the connection is released. The connection is made when the speeds of the driving member and driven member so permit. This includes a hub on which a third clutch surface is formed continuously engaged with either the first clutch surface or the second clutch surface and adapted to engage selectively either the second clutch surface or the first clutch surface with which the hub is not continuously engaged.
