4L80E [97-UP] Automatic Transmission Master Kit Performance HD Stage 1 Red

4L80E Master Rebuild Kit Performance Heavy Duty for 4L80E and 4L85E automatic transmissions, 1997 and later. Built around Stage 1 Red Clutches and Kolene Steels. Includes Stage 1 performance frictions, steels and gasket and seal set for a complete overhaul. 3 pieces in 3 components.

• Stop chasing parts separately: this kit covers the clutch pack, full overhaul gaskets, and Kolene steel module in one box, reducing sourcing time before the rebuild starts.
• No extra hard parts included: this kit does not contain bands, bushings, pistons, or an Automatic Transmission Filter. Review your parts list before ordering to confirm those items are already on hand.
• Three matched components built for performance: Stage 1 red friction clutches paired with a hi-performance Kolene steel module deliver increased heat resistance compared to standard replacement clutches and steels.
• Box contains exactly 3 pieces: 1 Stage 1 red clutch pack, 1 overhaul gasket kit for 97-UP units, and 1 hi-performance Kolene steel module. Total shipped weight is 11.7 lb.
• Before ordering, confirm your unit code is 4L80E or 4L85E and that the build year is 1997 or later. Kolene steels require proper transmission fluid compatibility, so verify fluid spec with your rebuild sheet.
