When the clutch pack in a 4L60E, 4L65E or 4L70E automatic transmission is the source of slip, burnt material or inconsistent engagement, replacing it with a correctly spec'd assembly is the most direct fix. This clutch pack uses red friction discs selected for Stage 1 rebuild applications in these three transmission families, covering units built from 1987 through current production.
The friction material in a clutch pack determines how the transmission transfers torque during each shift event. Red friction discs carry a specific coefficient of friction that suits Stage 1 use, which means this part is not interchangeable by feel or appearance with other friction grades. Using the wrong friction spec in a 4L60E, 4L65E or 4L70E can result in shudder, delayed engagement or repeat failure even when everything else in the rebuild is correct. Selecting the right stage from the start matters.
This is a single clutch pack assembly. It does not include steel separator plates, a band, Automatic Transmission Filter, gaskets or any other seals. If your rebuild requires those components, they need to be sourced separately. Reviewing your full parts list against the specific unit on the bench before placing an order will save time and avoid a stalled job waiting on missing pieces.
The part weighs 5.5 lb and ships as one assembly. Before ordering, verify the transmission code on the unit itself, confirm the model year falls within the 1987-to-present range, and make sure Stage 1 friction specification is the correct choice for the level of service this transmission will see. The 4L60E, 4L65E and 4L70E share family architecture but have differences that affect parts selection, so confirming the exact code removes guesswork.
- Red friction clutch pack addresses clutch slip and heat-related wear in Stage 1 applications, reducing the risk of repeated clutch failure in the unit.
- This listing covers the clutch pack only. It does not include steels, bands, Automatic Transmission Filter, gaskets or seals. Review your full rebuild parts list before ordering to avoid missing components.
- The red friction material used in this clutch pack is spec'd for Stage 1 performance levels, offering a defined friction characteristic suited to the demands of 4L60E, 4L65E and 4L70E rebuilds.
- Single clutch pack assembly. Shipping weight: 5.5 lb. Applies to 4L60E, 4L65E and 4L70E transmissions built from 1987 forward.
- Before ordering, confirm the exact transmission code stamped on the unit, the model year of the vehicle, and that Stage 1 friction spec matches the application you are rebuilding.
