The lock-up clutch includes a reaction plate, a clutch plate, and an anti-rattle plate. The reaction plate is fixed to the front cover and includes a plurality of windows circumferentially spaced from each other. The clutch plate includes a plurality of tabs each engaged with the reaction plate via one respective window. The anti-rattle plate is fixed relative to the front cover and engaged with each of the plurality of tabs in the corresponding windows. ## Claims ### Claim 1 A torque converter, comprising: a front cover arranged to receive a torque; a lock-up clutch engaged with the front cover, the lock-up clutch including: a reaction plate fixed to the front cover, the reaction plate including a plurality of windows circumferentially spaced from each other; a clutch plate including a plurality of tabs each being engaged with the reaction plate via one respective window; and an anti-rattle plate fixed relative to the front cover and engaged with each tab in the corresponding windows. ### Claim 2 (depends on 1) The torque converter of claim 1, wherein the anti-rattle plate circumferentially compresses each tab against the reaction plate in the corresponding windows. ### Claim 3 (depends on 1) The torque converter of claim 1, wherein the plurality of tabs are configured to receive a drive torque and transmit a coast torque. ### Claim 4 (depends on 1) The torque converter of claim 1, wherein the clutch plate includes a plurality of further tabs each being engaged with the reaction plate via one respective window, each of the plurality of tabs being circumferentially spaced from each of the plurality of further tabs. ### Claim 5 (depends on 4) The torque converter of claim 4, wherein the plurality of tabs and the plurality of further tabs are alternatingly arranged circumferentially about the clutch plate. ### Claim 6 (depends on 4) The torque converter of claim 4, wherein each of the plurality of further tabs are configured only to receive a drive torque, and the plurality of tabs are configured to receive the drive torque and to transmit a coast torque. ### Claim 7 (depends on 1) The torque converter of claim 1, wherein the anti-rattle plate includes a plurality of fingers circumferentially spaced from each other, each finger contacts one respective tab in one respective window. ### Claim 8 (depends on 7) The torque converter of claim 7, wherein the plurality of fingers extend radially outward from an outer diameter of the anti-rattle plate. ### Claim 9 (depends on 1) The torque converter of claim 1, wherein each window includes a drive side and a coast side spaced circumferentially from the drive side, the plurality of tabs each being in contact with the drive side of the respective window and being spaced from the coast side of the respective window. ### Claim 10 (depends on 9) The torque converter of claim 9, wherein the clutch plate is arranged to receive a drive torque via interfaces between each tab and the respective drive side of the corresponding windows. ### Claim 11 (depends on 9) The torque converter of claim 9, wherein the anti-rattle plate includes a plurality of fingers each configured to engage one respective tab, each finger contacts the one respective tab in the one respective window. ### Claim 12 (depends on 11) The torque converter of claim 11, wherein each of the plurality of fingers is spaced from the respective coast side of the one respective window. ### Claim 13 (depends on 12) The torque converter of claim 12, wherein the clutch plate is arranged to transmit a coast torque via interfaces between each finger and the corresponding tabs. ### Claim 14 (depends on 1) The torque converter of claim 1, wherein: the reaction plate includes a plurality of notches circumferentially spaced from each other, each notch being arranged between two circumferentially adjacent windows of the plurality of windows; and the anti-rattle plate includes a plurality of fingers fixed to the front cover, each of the fingers extending through one respective notch. ### Claim 15 (depends on 14) The torque converter of claim 14, wherein the anti-rattle plate includes a plurality of further fingers each arranged circumferentially adjacent to one respective finger, each further finger extending through one of the two circumferentially adjacent windows. ### Claim 16 (depends on 15) The torque converter of claim 15, wherein each tab is arranged circumferentially between one respective finger and one respective further finger. ### Claim 17 (depends on 15) The torque converter of claim 15, wherein the plurality of further fingers are arranged to receive a coast torque from the clutch plate. ### Claim 18 (depends on 17) The torque converter of claim 17, wherein each tab is in contact with the reaction plate and one respective further finger in the one of the two circumferentially adjacent windows. ### Claim 19 (depends on 1) The torque converter of claim 1, wherein the clutch plate is disposed axially between the anti-rattle plate and the front cover. ### Claim 20 A method for assembling a torque converter, comprising: providing a front cover defining a cavity; inserting a clutch plate into the cavity, wherein the clutch plate includes a plurality of tabs; providing a reaction plate including a plurality of windows circumferentially spaced from each other; coupling the clutch plate to the reaction plate by inserting each of the tabs into one respective window; aligning an anti-rattle plate relative to the reaction plate; pressing the anti-rattle plate into the cavity; rotating the anti-rattle plate relative to the reaction plate to compress the tabs against the reaction plate in the respective windows; and fixing the anti-rattle plate relative to the front cover.
