Abstract
A multiple ratio transmission having planetary gearing with clutches and brakes for establishing selectively each gear ratio, a hydrokinetic torque converter connecting a torque input shaft to a torque input shaft for the gearing and a hydrokinetic torque converter bypass friction clutch for connecting the torque input shaft directly to one of the torque input elements of the planetary gearing whereby the transmission may be conditioned for (i) open converter power drive mode, (ii) a normal drive mode wherein the converter is operated with an open bypass clutch during low speed ratios and wherein a split torque delivery is achieved in a higher speed ratio and wherein the torque converter is bypassed through the clutch during operation in the highest speed ratio, and (iii) an economy light throttle drive mode wherein the transmission is conditioned for open converter operation in the low speed range and for operation with the bypass clutch fully engaged for each of the higher speed ratios.
