Abstract
A four-speed transmission with an overdrive, high-speed ratio comprising multiple ratio torque transmitting gear elements wherein one gear element serves as a reaction element for intermediate speed operation as well as for overdrive operation with the direction of reaction torque distribution to a reaction element during intermediate speed ratio operation being opposite to the direction the reaction torque distributed to that same element during overdrive operation, and double acting brake servos for effecting optimum reaction braking for both intermediate speed operation and overdrive operation, the servos being hydraulically interconnected through a common shift valve circuit for timed engagement and release.
