TCI® - The #1 Name In High Performance Transmissions & Torque Converters
Every TCI® automatic transmission and drivetrain component is designed, built, and tested by hardcore racers and street performance enthusiasts, and we have never forgotten that performance is defined by results –both at the track and on the street.

 

From Late Model Street To Serious Race, TCI® Has The Right Combination
We make the finest performance drivetrain components for everything from late-model Corvettes, Camaros, and Mustangs, to Dodge Cummins, Power Stroke Ford, and GM Allison diesel-powered RVs and light trucks. Our street performance, drag race, and oval track lineup includes AMC and Chrysler Torque Command, Torqueflight, and A500 /A518, Ford C4, C6, AOD, AODE, 4R70W, 5R55, E4OD, and 4R100; GM /Chevrolet Powerglide, Turbo 350 & 400, 200C, 200-4R, 700-R4, 4L60E, 4L65E, 4L80E, and 4L85E and more!

 
TCI® - Triple Tested For Unmatched Performance & Quality
Every TCI® product is backed by nearly four decades of high-performance drivetrain technology and engineering expertise. Our automatic transmissions deliver increased fluid flow and lubrication, superior thrust capacity, and most of all –higher horsepower capability! Our policy of replacing problematic
factory hard parts with stronger components* -many of which are our own patented designs, ensures durability that can’t be beat. Our transmissions and valve bodies are meticulously inspected in our state of the art QC facility using hydraulic-circuit & dyno testing; and every converter is leak-checked & computer balanced.

Finally, each and every TCI® transmission is subjected to the industry’s most demanding fluid pressure and dyno testing before it’s ever allowed to leave our warehouse. Looking for the most rear wheel horsepower for your hard-earned performance dollar? Look no further than TCI®!
