    • A multiple speed ratio hydrokinetic transmission for a wheeled vehicle comprising a planetary gear set (20) having two input torque flow paths and a hydrokinetic torque converter (18) having an impeller element (38) connected to one flow path and a turbine element (40) connected to the other flow path; a friction lockup clutch (164) which, under relatively high speed driving conditions, establishes a mechanical torque bypass path for engine torque in parallel with a torque path established by the hydrokinetic unit (18); and an overrunning coupling (152) located between the friction clutch and the turbine element (40) 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 (164) and the overrunning coupling (152) thereby providing improved driveline efficiency and improved driveability for the driveline with reduced harshness in ratio changes.

    • PURPOSE: A six-speed shifting method for an automatic transmission of a vehicle is provided to reduce development cost for a new power train by operating six-speed drive with an existing five-speed power train and to improve durability by controlling a side shifting unit of fifth and sixth gears in a direct coupling. CONSTITUTION: A power train of an automatic train for a vehicle includes a main shifting unit and a side shifting unit. The main shifting unit hooks up with three clutches, two brakes and an one-way clutch as two single pinion planetary gear sets. The side shifting unit hooks up with a clutch, a brake and a one-way clutch as the single pinion gear set. The main shifting unit outputs same deceleration in forward one and two-speeds, deceleration in forward three-speed, same speed in forward four and five-speeds and acceleration in forward six-speed. The side shifting unit outputs deceleration in forward one, three and four-speeds and same speed in forward two, five and six-speeds. Therefore, Six-speed drive is operated by using an existing five-speed power train. Driving performance is improved by reducing shifting difference for each deceleration level. Shifting feeling is improved by limiting a shifting level between two-speed and three-speed and between four-speed and two-speed to control the main shifting unit and the side shifting unit at the same time.
