TH400 Gasket & Seal Kit w/Teflon Rings

The FTI Performance TH400 Gasket & Seal Kit with Teflon Rings is a comprehensive overhaul gasket set designed specifically for the Turbo 400 transmission. This kit is essential for transmission builders, restoration shops, and automotive enthusiasts who are undertaking a full TH400 overhaul. It provides all the necessary composite gaskets and seals required for a complete transmission teardown and reassembly.

The inclusion of Teflon rings in this kit ensures reliable sealing in high-pressure and thermally cycling areas. The composite gasket material is engineered to resist oil degradation and maintain integrity across the typical operating temperature range of street and performance applications. This quality gasket kit helps prevent oil leaks from pan flanges, case seams, and internal passages, which can be problematic in poorly rebuilt transmissions.

Whether you are refreshing an original TH400 or upgrading a vehicle with this proven transmission platform, sourcing a verified kit ensures you have every gasket and seal specification needed. Professional transmission rebuilders and DIY builders restoring street rods, muscle cars, classic trucks, and performance vehicles will find this kit invaluable for streamlining the rebuild process and avoiding repeat disassembly.
