MULTISPEED POWER TRANSMISSION Abstract of the Disclosure A multispeed transmission has a planetary gear arrangement and two pair of countershaft gears. The countershaft gears are drivingly connectible between the output of the planetary gear arrangement and the output shaft of the transmission. One pair of the countershaft gears provides a rotating reaction for the planetary during one speed ratio and a reduction ratio during at least one other speed ratio. The other pair of countershaft gears provides a reduction ratio from the planetary during the one speed ratio and a single reduction ratio between the transmission input and the transmission output in at least one other speed ratio. The planetary transmission is controlled by clutches and brakes to establish a reduction ratio, a direct drive and an overdrive ratio.
