<p>A transaxle driveline for a wheeled vehicle having an engine and gear system on a common axis that is transverse with respect to the center plane of the vehicle and having tandem driveshafts for the traction wheels, a differential gear mechanism mounted on a countershaft situated in prallel relationship with respect to the axis of the engine, the differential drive gearing being located between multiple ratio planetary gear elements (12) of the driveline and hydrokinetic torque converter (10) and a compact clutch-and-brake (CL,, CL2 and CL3 resp. B1 and B2) arrangement for various ratios to be shifted in the multiple ratio gear system within a transmission housing having a minimum axial dimension, the gearing being adapted to provide four forward driving ratios including an overdrive ratio and direct drive ratio, the latter having three operating modes, one of which is fully mechanical, one of which is hydrokinetic and the third of which is characterized by a split torque delivery path that is partly hydrokinetic and partly mechanical.</p> |
