Th350 Master Overhaul Ki

The TCI TH350 Master Overhaul Kit is a complete transmission rebuild solution engineered for TH350 automatic transmissions requiring full restoration or high-performance modification. This comprehensive master racing overhaul kit supplies all internal wear components—clutches, steel friction plates, bands, sealing gaskets, and transmission filter—needed to restore hydraulic integrity and shift quality to factory specification or beyond.

The kit's component selection reflects TCI's racing heritage and transmission engineering expertise. The clutch and steel package is designed to withstand the thermal and mechanical demands of both street and strip driving, while the included gasket and seal set ensures proper pressurization and eliminates internal leakage that causes delayed engagement, soft shifts, or pressure loss. The transmission filter removes debris accumulated during the rebuild process, protecting newly installed components from contamination. At 9.85 lbs, the kit contains densely packed friction material and precision-engineered sealing surfaces—indicative of a substantive rebuild package rather than a maintenance-level offering.

This kit is intended for rebuild technicians, transmission specialists, and serious enthusiasts undertaking a complete TH350 overhaul. It serves both restoration applications—returning worn transmissions to stock performance—and performance builds where improved shift firmness and durability are priorities. The master-level specification means it addresses all wear surfaces in a single package, eliminating the need to source components individually and reducing the risk of partial rebuild failure.

The TH350 remains one of the most widely deployed three-speed automatics in classic and modified vehicles, from muscle cars to light trucks. Whether rebuilding a stocker or preparing a transmission for performance-modified engine output, having the correct friction material composition and sealing surfaces is critical to reliability and shift quality. TCI's master kit consolidates the variables into one verified package.
