10L90 [17-UP] Automatic Transmission Steel Clutch Pack

A single steel clutch plate sized for the 10L90 automatic transmission, also applicable to the 10L80, covering units produced from 2018 onward. Where a full kit is not needed, this plate lets a technician replace the one worn or damaged component in the clutch pack without purchasing parts that will sit unused on the shelf.

The 10L90 and 10L80 share a ten-speed architecture that distributes load across multiple clutch packs, and a steel plate that has lost its flatness or surface integrity directly affects engagement in whichever pack it serves. Replacing that plate with one that meets the stock dimensional requirements restores the contact surface the friction disc relies on to transfer torque cleanly. No machining or fitting work should be needed: the plate is selected to match the stack geometry of these units.

At REMCO, parts like this one are. The plate is picked individually, checked against the part record, and boxed with a contents list so the technician receiving it can confirm what arrived before opening the bench. REMCO has worked in automatic transmission parts since 1991, and that process has not changed.

Before placing the order, confirm the transmission identification code stamped on the unit, the model year of the vehicle, and the specific clutch pack location this plate is intended for. Stack depth and plate count can vary within the same transmission family depending on build date and assembly line, so cross-referencing the position is the step that helps avoid a return.

• Restores clutch pack engagement in 10L80 and 10L90 units from 2018 onward, addressing slip and delayed shifts caused by worn steel plates.
• This listing is a single steel clutch plate only. No friction discs, no seals, no Automatic Transmission Filter, and no other components are included. Verify your full parts list before ordering.
• The plate dimensions are matched to 10L90 specifications so it seats flush against the friction discs without requiring additional machining or shimming to fit the stack.
• Single steel clutch plate, 14 lb shipping weight. Sourced individually and checked against part records before packing. A parts list is included in the box.
• Before ordering, confirm the transmission code on the unit, the model year, and the exact clutch pack position this plate is needed for, as stack thickness varies by application.
