ABSTRACT:
A multiple ratio automotive vehicle transmission having a hydrokinetic torque converter and a compound planetary gear unit that establish a plurality of underdrive ratios, a direct drive ratio and an overdrive ratio, the ratio changes from the first underdrive ratio to a second underdrive ratio from the second underdrive ratio to the direct drive ratio each being established by engagement by a single torque establishing device, brake means for controlling application and release of the torque establishing devices to effect transmission of reaction torque from a reaction element of the gearing to a stationary portion of the mechanism, said controlling means being adapted to establish optimum shift points during ratio changes regardless of the magnitude of the torque being delivered at the instant a ratio shift occurs.
