The Choice on the Street is TCI Transmissions!
TCI Streetfighter Transmissions are ideal for vehicles powered by non-supercharged engines producing 400 to 775 horsepower, using pump gasoline. Equipped with a TCI manual/automatic valve body, the StreetFighter Transmission allows you to shift manually into each gear or to remain fully automatic by placing it in Drive. The valve body, however, permits downshifting if the engine speed is lowered to the low gear operating range. To function properly, all throttle linkage, vacuum lines, and kickdown components must be connected. TCI's high standards ensure that you can expect dependable and long-term performance.

If you’re building a serious street machine, you need a transmission that can keep up. The TCI StreetFighter Transmissions line is engineered for power, durability, and shift control—designed specifically for non-supercharged vehicles making between 400 and 775 horsepower on pump fuel.
One standout in the lineup is the TCI Streetfighter TH350, built to improve every shift and boost reliability in hard-launch, hard-use applications. It features upgraded clutches and bands, sprags and roller clutches with increased holding capacity, an improved lubrication system, and a high-pressure valve body to help reduce slippage and preserve performance under load.
These units offer flexibility too: the valve body supports both automatic and manual shifting. You can lock it in “Drive” for traditional auto performance or manually shift through the gears for better control off the line. Down-shift protection ensures engine speed stays safe if you slow down to a lower gear range.
When you need torque capacity and consistent, firm shifts, the TCI Turbo 350 options in the StreetFighter family are built to handle up to roughly 500 ft-lb of torque in non-boosted setups—meaning this isn’t just a show trans, it’s ready for real power.
For anyone wanting to replace a stock TH350 and get the most out of their drive, the tci th350 in StreetFighter form delivers upgrades that add up: durability, performance, and shift quality improvement. Add one to your project and enjoy launching, shifting, and driving with confidence.
