GM 700R4 Transmission Streetfighter

This TCI 700R4 Streetfighter is a 4-speed automatic built for street-driven GM vehicles that need strong reliability and sharper throttle response. Hot rod builders and classic car fans love it because it brings modern shift quality to older platforms while keeping that vintage look.

TCI tuned the valve body and refined internal friction management to cut lag and boost overall performance. Power delivery stays smooth, and fuel economy gets a bump too. Everything runs mechanically with no electronics needed, keeping the setup simple and dependable.

Built as a direct bolt-in for vehicles that came with a 700R4 or similar Turbo 350-based platform, this transmission fits street rods, restomod builds, and truck conversions without heavy modifications. It handles the demands of high-output engines on the street while delivering improved performance day after day.
