When stock friction material starts glazing or holding inconsistently in a 4L80E or 4L85E, swapping in a Stage 1 red clutch pack is one of the first moves a transmission technician makes. This is a single red friction clutch pack designed specifically for 4L80E and 4L85E automatic transmission units built between 1991 and 2016, and it is sold as an individual component, not as part of a rebuild kit.
The red friction compound handles heat differently than standard gray material. In applications where the unit sees repeated high-load shifts, towing duty, or performance use, conventional frictions tend to glaze over time, which leads to soft engagement and eventual slippage. The Stage 1 red material is formulated to maintain consistent grip under those conditions, giving the clutch pack a more defined apply feel and extending the service interval before wear becomes an issue.
This listing covers one clutch pack friction assembly. There are no steels, no Automatic Transmission Filter, no gaskets, no seals, and no other components included. If your repair requires a full friction and steel set or a complete overhaul kit, you will need to source those pieces separately. Check your parts layout against what this item covers before placing the order.
The item weighs 2 lb. Application is 4L80E and 4L85E transmissions, model years 1991 through 2016. Confirm the transmission identification code stamped on the unit before ordering, as related transmission families can look similar but require different components.
- Stage 1 red friction material delivers firmer, more controlled engagement in 4L80E and 4L85E units, reducing slippage under load compared to standard gray friction material.
- THIS IS A SINGLE CLUTCH PACK PIECE ONLY. No steels, no Automatic Transmission Filter, no seals, no rebuild kit included. Review your parts list carefully before ordering to avoid a return trip.
- Red friction compound is formulated for higher heat tolerance in performance and heavy-duty applications where stock frictions tend to glaze or wear prematurely under repeated high-load shifts.
- Single clutch pack friction assembly, Stage 1 red material, fits 4L80E and 4L85E transmissions, model years 1991 through 2016. Item weight: 2 lb.
- Before ordering, confirm your transmission code on the unit itself matches 4L80E or 4L85E and verify the model year falls within the 1991-2016 application range.
