Zusammenfassung:	An automatic transaxle for use in an automotive vehicle driveline including a compound planetary gearset (16), a hydrokinetic unit (12) and a torque splitter gear unit (14) that cooperate to define torque delivery paths from the vehicle engine to a driven gear (64); the driven gear (64) being located between the hydrokinetic unit (12) and the compound planetary gearing (16) and the torque splitter gear unit (14) being located within the housing for the hydrokinetic unit (12); and clutch-and-brake means for establishing and disestablishing each of the forward driving ratios and the reverse drive ratio, the clutch-and-brake means being arranged in a compact fashion within the housing (74) for the compound planetary gearing (16) to provide a minimum axial length of the assembly; the driven gear (64) being connected drivably to the vehicle traction wheels through a differential gearing mechanism (75); the hydrokinetic unit (12), the gearing (16) and the differential mechanism being enclosed in a common cast housing (70).
