8L90 C3 [15-UP] Automatic Transmission Friction Plate (1 3 5 6 7) (Waved)

When rebuilding the C3 clutch pack in an 8L90 automatic transmission, using the correct plate geometry for each position is not optional: the waved profile in positions 1, 3, 5, 6, and 7 is what allows the pack to apply smoothly and hold load without chatter. This is a single waved HT friction clutch plate sourced for exactly that application, not a flat plate and not a general-fit substitute.

The 8L90 is a complex unit, and the C3 pack in particular sees significant heat and load cycles. The high-temp friction material on this plate is suited for that environment. At 7 lb, it is a solid, full-thickness piece, not a lightweight substitute.

This listing covers one plate. It does not include steel plates, separator plates, seals, an Automatic Transmission Filter, a band, or any other component. If your rebuild calls for the full clutch pack or additional hardware, those need to be sourced separately. Verify your parts list against what you actually need before placing the order.

This plate applies to 8L90 transmissions in the C3 clutch pack, model designation C3, for units from 2015 and up. Before ordering, confirm the transmission code stamped on the unit matches 8L90, identify that the pack you are working on is the C3, and check that your production date falls within the covered range. A mismatch in any of those three points means this is not the right plate for your job.

• Replacing a worn C3 friction plate in an 8L90 unit stops clutch pack slippage and avoids repeated teardowns caused by using the wrong plate type for those positions.
• This listing is for one friction plate only. It does not include steels, seals, Automatic Transmission Filters, bands, or any other clutch pack components. Confirm the full scope of your rebuild before ordering.
• The waved profile of this plate is specific to positions 1, 3, 5, 6, and 7 in the C3 clutch pack of the 8L90. Using a flat plate in those positions will not replicate the correct clutch feel or apply pressure the pack needs.
• One waved HT friction clutch plate for the 8L90 C3 clutch pack, positions 1 3 5 6 7. Item weight: 7 lb. Single unit per order.
• Before ordering, verify the transmission code is 8L90, confirm this is the C3 clutch pack, and check that your application falls within the 2015-and-up production range.
