Abstract: A multiple speed ratio hydrokinetic transmission for a wheeled vehicle comprising a planetary gear set having two input torque flow paths and a hydrokinetic torque converter having an impeller element connected to one flow path and a turbine element connected to the other flow path; a friction lockup clutch which, under relatively high peed driving conditions, establishes a mechanical torque bypass path for engine torque in parallel with a torque flow path established by the hydrokinetic unit; and an overrunning coupling located between the friction clutch and the turbine element to adapt the transmission for a direct mechanical torque transfer from the vehicle engine to a driven member or a split torque path that is partly mechanical and partly hydrokinetic; provision being made during high speed ratio operation for a regenerative torque distribution between the input elements through the friction clutch and the overrunning coupling thereby providing improved driveline efficiency and improved driveability fo
