A power transmission having axially aligned input and output shafts is provided with a planetary gear train for each shaft respectively with the carriers for the planetary pinions interconnected, with the pinions all meshing with a common ring gear, and with a gear reduction from the input gear train to the output gear train. Power is applied to the transmission through a torque convertor, and initial high torque-low speed operation changes gradually until a one-to-one ratio is established.
