66-'76 C6 Pro Super Kit.

TCI Pro Super Kits are transmission overhaul kits for your vehicle that contain the same parts and pieces used in building TCI StreetFighter Transmissions. They include gaskets, a seal kit, pan gasket (reusable type), new performance frictions, steel clutches, bands, adjustable modulator and a high-volume filter and drain plug kit. The Pro Super Kit also contains a TCI Trans-Scat Valve Body Kit, which enables you to change the valve body to a manual/automatic setup that delivers both a good solid shift suitable for towing applications or a competition quality shift for drag racing.
