Abstract
A manual planetary power transmission includes two planetary gearsets and three torque-transmitting synchronizer assemblies. Two of the synchronizer assemblies permit the control of one gear member of the planetary gearsets individually. The third synchronizer permits control of two of the planetary gear members individually or simultaneously. The three synchronizer assemblies are manipulable in combinations of three to provide six forward speed ratios and one reverse speed ratio in the planetary gearsets.
