StreetFighter TH350 Automatic Transmission

The TCI StreetFighter TH350 Transmission is engineered for Chevy engine applications, built to withstand the demands of high-performance street machines. This unit features special clutches and bands for enhanced durability, along with new sprags/roller clutches to increase holding capacity. An improved lubrication system directs more fluid to the planetaries and internals, ensuring longevity. The transmission includes a chrome-plated pan with an embossed TCI logo, and offers higher line pressure for extra-firm shifts and reduced slippage. This particular package, 311000P3, includes the Super StreetFighter Converter, which provides a 2,000+ RPM increase in stall over stock. The transmission itself is a 3-speed unit with a 2.52 first gear ratio, 1.52 second gear ratio, and a 1.00 third gear ratio. It is rated to handle up to 575 horsepower and is designed for non-supercharged systems using pump gasoline. The TCI TH350 StreetFighter Transmission is compatible with 1969-1979 GM TH350 applications for Small and Big Block Chevy engines, as well as the 4.3L V6. It features a 6-inch tailshaft and a non-lock-up converter. The package includes the transmission, converter, dipstick, detent downshift cable, and fluid.
