TCI Trans-Scat Valve Body Kits

TCI Trans-Scat valve body kits offer you two options: you can either have good, solid shifting that's well suited to towing, or you can have competition-style shifting. These kits eliminate slippage and lag, improve fuel economy, extend clutch life, and really improve the 2nd and 3rd gear shifts. In addition to delivering crisper shifting, they allow you to downshift on demand, and most will allow you to hold first gear for extended periods, such as when climbing long hills while towing. All kits give you the full range of normal automatic functions when in "drive."

TCI StreetFighter Transmissions

TCI StreetFighter transmissions are durable enough to withstand the rigors of even the toughest street machines. Equipped with a manual/automatic valve body, most units allow you to manually shift the vehicle into each gear change or, by placing it in the drive position, remain fully automatic. In either mode, you get a race track shift that bangs through the gears and shaves time off of your ETs. When you use the manual gear selection feature, the StreetFighters upshift and downshift right when you move the lever, with no lag or governor override. When you select the normal drive position, they retain positive automatic shifts for the ease of driving you look for in an automatic transmission.

TCI Trans-Brake Valve Body Kits

TCI trans-brake kits allow you to achieve maximum torque converter stall for quicker and more consistent reaction and 60 ft. times. They work like this: When the trans-brake is engaged, the vehicle can roll neither forward nor backward, and as you press on the accelerator, the engine can rev as high as the torque converter stall. Once the brake is released, power is immediately transferred to the rear tires, with less parts breakage than with a manual transmission.
