A torque converter and multi-disc lock-up clutch has a pair of clutch discs splined to the input shell of the torque converter, a friction disc splined to the clutch piston intermediate the clutch discs and a friction pad secured to the clutch piston. The clutch piston is drivingly connected with the turbine of the torque converter. The clutch is controlled by fluid under pressure delivered to the torque converter such that during disengagement, the fluid passes between the clutch discs and the friction disc prior to entering the torque converter.

A torque converter and multiple disc lock-up clutch assembly wherein engagement and disengagement of the clutch is controlled by fluid flow reversal through the torque converter, said assembly comprising; an input shell; a first annular splined member secured to the inner surface of said input shell

A torque converter and multiple disc lock-up clutch assembly wherein engagement and disengagement of the clutch is controlled by fluid flow reversal through the torque converter, said assembly comprising; an input shell; a first annular splined member secured to the inner surface of said input shell; a clutch plate piston drivingly connected to the turbine of said torque converter; a clutch apply chamber formed by said turbine and said clutch plate piston; a second annular splined member secured to said clutch plate piston and being substantially concentric with and having lesser outer diameter than the inner diameter of said first annular splined member; a pair of annular clutch discs having splined outer diameters meshing with said first annular splined member; an annular clutch friction disc having a splined inner diameter meshing with said second annular splined member and being disposed intermediate and in controllable friction drive relation with said pair of annular clutch discs; an annular friction surface secured to said clutch plate piston adjacent to and in controlled friction drive relation with one of said pair of annular clutch discs and axially spaced from said annular clutch friction disc by said one annular clutch disc; and means for supplying fluid to said clutch apply chamber so that the clutch plate piston can be pressurized to enforce a friction drive in the clutch assembly between said annular clutch discs and said annular clutch friction disc and said annular friction surface.
