GM Transmission Parts — Rebuild Kits, Clutches, Filters & Hard Parts

Shop GM automatic transmission parts built for the units Detroit actually runs: 4L60E, 4L65E, 4L70E, 4L80E, 4L85E, 6L80, 6L90, 8L45, 8L90, TH350, TH400, and Powerglide.

This collection covers two jobs under one roof:

  • Everyday cars and SUVs — OEM-quality overhaul and master rebuild kits, filters, gaskets, seals, clutch packs, and wear items for a clean, reliable refresh on a daily driver or family vehicle.
  • Performance and heavy-duty builds — high-energy frictions, upgraded steels, HD clutch modules, and selected hard parts for street/strip 4L60Es, work-truck 4L80Es, and higher-horsepower 6L80 / 8L90 applications.

Dearborn Precision Performance Parts sources these components to the same standard we use on our stall converters: correct application by year and unit, premium friction where it matters, and parts that hold up under GM torque instead of coming back as a comeback. Match the kit or clutch pack to your year, transmission, and how the vehicle is used — daily miles or extra horsepower — then get it back on the road.

Browse by transmission family below, or start with a complete rebuild kit if you’re doing the whole job.
