Abstract
A power transmission has three axes on which rotatably supported gears and selectively operable clutches are disposed to provide five forward speed ratios. The two highest speed ratios (fourth and fifth) have identical input clutch and gear units. The fourth ratio, the torque transmission path, includes a transfer gear ratio and utilizes the second speed ratio gears to develop a speed ratio different from the fifth speed ratio.
