ABSTRACT:
A change-speed transmission for a passenger automobile has a compound gear train which gives four forward speeds and a reverse. The compound gear train includes two basic planetary gearsets and a dual-pinions planetary gearset located between the two basic planetary gear sets. All the ring gears are connected with each other for simultaneous rotation and act as a reaction member, to provide a first forward speed, for one basic planetary gearset which has a carrier as an output, sun gear of which being connected to carrier of the dual-pinions planetary gearset, the sun gear of the one basic planetary gearset and the carrier of the dual-pinions planetary gearset being connectable to an input during all forward speeds. Sun gears of the dual-pinions planetary gearset and other basic planetary gearset are connected with each other for simultaneous rotation. The carrier of the other basic planetary gearset is brakeable to give second forward speed, and the sun gears of the other basic planetary gearset and dual-pinions planetary gearset are brakeable to give third forward speed and the last mentioned sun gears are connectable to the input to give fourth forward speed.
