ABSTRACT:
A transmission for an automotive vehicle, includes an input shaft, an ouput shaft, a coupling device having an input portion thereof connected to the input shaft, and a gear mechanism for transmitting the power from the input shaft to the output shaft in such a way that three forward and one reverse drives can be obtained. The gear mechanism including first, second, third and fourth rotatable members. The fourth rotatable member is connected to the output shaft. In addition, first and second clutches are provided between the gear means and the coupling device. The first clutch is connected to the first rotatable member of the gear mechanism. The second clutch is connected to the second rotatable member of the gear mechanism. First brake selectively brakes the third rotatable member of the gear mechanism. Second brake selectively brakes the second rotatable member of the gear mechanism. Further, the transmission includes a third clutch connected to the input shaft, and a planetary gear set having fifth, sixth and seventh rotatable members. The sixth and seventh rotatable members are connected to the gear mechanism. The fifth rotatable member is connected to the third clutch.
