Automatic transmission gear and clutch arrangement

A multi-speed transmission comprising:

• a transmission housing having a center support and a front support, the center support including a first apply fluid passage, a second apply fluid passage, a third apply fluid passage, and a first dam fluid passage, and wherein the front support includes a fourth apply fluid passage and a second dam fluid passage;
• a first, a second, a third, and a fourth planetary gear set each having a first, a second, and a third member;
• five torque-transmitting mechanisms each having a first apply chamber and a piston for selectively interconnecting at least one of the first, second, and third members of the planetary gear sets with at least one other of the first members, second members, and third members of the planetary gear sets, and the transmission housing, and wherein the first apply fluid passage is in communication with the first apply chamber of a first of the five torque-transmitting mechanisms, the second apply fluid passage is in communication with a second apply chamber of the first of the five torque-transmitting mechanisms, the first dam fluid passage is in communication with a dam chamber of the first of the five torque-transmitting mechanisms, the third apply fluid passage is in communication with the first apply chamber of a second of the five torque-transmitting mechanisms, the fourth apply fluid passage is in communication with the first apply chamber of a third of the five torque-transmitting mechanisms, and the second dam fluid passage is in communication with a dam chamber of the third of the five torque-transmitting mechanisms;
• an input member continuously interconnected to one of the first, second, and third members of one of the planetary gear sets, the input member having:
• a first, a second, and a third bore disposed parallel to a longitudinal axis of the input member;
• a first input port in communication with the first bore and a second input port in communication with the third bore;
• a first and second dam port in communication with the second bore;
• a first apply port in communication with the first bore;
• and
• a second apply port in communication with the third bore;
• an output member continuously interconnected to at least one of the first, second, and third members of one of the planetary gear sets;
• an intermediate member rotatably fixed to the first member of the fourth planetary gear set, the intermediate member having:
• an intermediate bore in communication with the second bore of the input shaft;
• a first apply side port in communication with the first apply chamber of a fourth of the five torque-transmitting mechanisms;
• a second apply side port in communication with the first apply chamber of a fifth of the five torque-transmitting mechanisms;
• a first dam side port in communication with a dam chamber of the fourth of the five torque-transmitting mechanisms;
• and
• a second dam side port in communication with a dam chamber of the fifth of the five torque-transmitting mechanisms and the intermediate bore;
• and
• a plurality of interconnecting members continuously interconnecting one of the first, second, and third members of the planetary gear sets with another one of the first, second, and third members of the planetary gear sets.
