ABSTRACT:
A hydrokinetic multiple ratio transmission having a compound planetary gearset with clutches and brakes that are selectively engageable and released to establish two underdrive ratios, a direct drive ratio and an overdrive ratio, as well as a reverse ratio, the clutches and brakes being operable by fluid pressure operated servos, the clutches and brakes for establishing the underdrive ratios and the direct drive ratios being disposed between the planetary gearing and a hydrokinetic torque converter, a friction clutch engageable for overdrive operation and disposed on the opposite side of the planetary gearing and two torque input shafts, one being concentrically disposed with respect to the other, the torque input shaft for overdrive operation being connected to torque input portion of the overdrive clutch through an intermediate shaft adapted for articulation to accommodate eccentricities between the bearing supports disposed on opposite sides of the planetary gearing.
