A multi-speed transmission includes an input shaft, an output shaft, and a planetary
gear arrangement having three planetary gear sets. The input shaft and output shaft
are continuously connected with members of the planetary gear sets. Six torque-transmitting
mechanisms selectively connect specific members of the planetary gear sets with
other members of the planetary gear sets, or with the transmission housing. Fluid
for applying two of the torque-transmitting mechanisms is carried through a shaft
which is connected to a sun gear of the first planetary gear set. The six torque-transmitting
mechanisms are engaged in combinations of three to establish seven forward speed
ratios and a reverse speed ratio between the input shaft and the output shaft.
