  • Publication number: 20060266614
    Abstract: A clutch assembly for a transmission having a pressurized fluid source includes selectively engageable clutch plates including an apply plate. A piston is movable between an apply position and a release position to respectively engage or release the clutch plates. An apply plate cover cooperates with the apply plate to at least partially form an annular cavity that is sealed to contain pressurized fluid provided by the pressurized fluid source when the piston is moved to the apply position, thereby allowing pressurized fluid flow radially inward across the engaged clutch plates. The annular cavity is opened to allow fluid to empty therefrom when the piston is moved to the released position, thereby allowing centrifugally pumped fluid to flow radially outward across the released clutch plates. A method of reversing cooling fluid flow across clutch plates is also provided.

  • Publication number: 20050090361
    Abstract: A compact longitudinal transmission has an input shaft rotatably supported in a front end wall, an output shaft rotatably supported in a rear end wall, and a housing interconnecting the front end wall and the rear end wall. Three planetary gearsets disposed within the housing are controlled by five torque-transmitting mechanisms including four friction disc or plate mechanisms and one band mechanism. The band mechanism being disposed radially outboard of the rearmost one of the planetary gearsets.

  • Publication number: 20050090354
    Abstract: A power transmission includes three interconnected planetary gearsets and five selectively engageable torque-transmitting mechanisms. The planetary gearsets and torque-transmitting mechanisms are disposed within a transmission housing. The torque-transmitting mechanisms are selectively engageable to provide six forward speed ratios and one reverse speed ratio in the planetary gearsets between an input shaft and an output shaft.

  • Publication number: 20050090352
    Abstract: A power transmission has three planetary gearsets, which are interconnected and also having at least one member continuously drivingly connected with an input shaft. Two of the planetary gearsets are connected with an output shaft. Five torque-transmitting mechanisms are disposed between two end walls and an outer housing, which define four spaces within the power transmission. The torque-transmitting mechanisms are disposed within two or more of the four spaces or combinations of two of the spaces.

  • Publication number: 20050090360
    Abstract: A power transmission has three planetary gearsets, which are selectively controlled by five torque-transmitting mechanisms to establish six forward speed ratios and one reverse speed ratio for the transmission. The torque-transmitting mechanisms include piston mechanisms, which are slidably disposed within members of the transmission housing including a front end cover, a rear end cover, and a shell interconnecting the front end cover and the rear end cover.
