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

When the C3 clutch pack in an 8L90 automatic transmission shows friction material wear at positions 1, 3, 5, 6, or 7, replacing the individual plate at the correct thickness is the direct path back to proper clutch apply. This listing covers a single HT friction clutch plate at .063 inch thickness, specified for those five positions within the C3 pack of the 8L90, and nothing else.

The 8L90 is a demanding eight-speed unit, and the C3 clutch pack sees repeated thermal cycling under normal operation. The .063 specification is not interchangeable with other thickness variants that may appear in different positions of the same pack, so matching the plate to the correct position number before installation matters. If your diagnosis points to C3 and the worn plate falls in positions 1, 3, 5, 6, or 7, this is the part that fits that slot.

This is a single-piece listing. There are no steels, no seals, no Automatic Transmission Filter, no band, and no additional hardware included. If your repair calls for a full friction and steel set or a complete overhaul kit for the 8L90, that would be a separate purchase. Review your parts list against what is shown here before placing the order.

The year range for this application runs from 2015 through the current model year. Confirm the unit code on the transmission before ordering, and cross-reference the C3 position map from your rebuild reference to be certain positions 1, 3, 5, 6, and 7 match your disassembly notes. Shipped weight is 7 lb.
