POWER TRANSMISSION Abstract of the Disclosure A power transmission has a planetary gear arrangement controlled by a plurality of selectively engageable clutches and brakes to provide forward and reverse speed ratios. A selectively operable input gear arrangement is utilized to establish a negative ratio of substantially 1:1 between the transmission input and the planetary gear arrangement. The selective use of the negative ratio input permits substantially equal forward and reverse drive ratios. The negative ratio input arrangement also permits extended coverage when employed with some of the other forward ratios established by the planetary gear arrangement.
