Abstract
A power transmission has a selectively controlled two-speed, underdrive and direct drive, planetary mechanism disposed between a torque converter and a multi-speed gear arrangement. A control for the two-speed planetary mechanism responds to vehicle operating parameters, such as throttle and brake, for establishing the selection of the ratio condition in the two-speed planetary mechanism.
