Saturday Night Special ®
The popular Saturday Night Special® torque converter delivers premium performance at a reasonable cost. A great choice for show cars and street rods, this converter incorporates many of manufacturing processes and performance features found in our more expensive full-competition models. Each one is pressure tested and balanced prior to shipment.

Breakaway ®

The first step into serious high performance, the Breakaway® is a great torque converter for moderately modified street machines and weekend racers also used as daily drivers. It provides approximately 2400 to 2600 rpm flash stall with out negatively affecting part throttle driving. Designed for efficiency at highway cruising speeds and to launch hard at wide open throttle, the Breakaway® is a fantastic all-around torque converter.

StreetFighter ®

Designed with the street racer in mind, this torque converter benefits more radically prepared street machines (those with performance cams, aftermarket carbs and higher compression ratios) to bring the launch rpm in line with the performance enhancements. The StreetFighter® lets you take advantage of horsepower gains found in highrer rpm ranges.

Super StreetFighter 

This line of performance converters was developed to work with many GM and Ford late model lock-up transmissions. These transmissions can offer many advantages to performance enthusiasts, including lower initial gear ratios and overdrive gear for lower highway rpm and improved mpg. The Super StreetFighter™  lock-up series allows the car owner to have to 4000 rpm stall speeds (depending on application) while still enjoying all the benefits of a mechanical lock-up converter.

New! Ultimate StreetFighter 

Our latest line of torque converters designed specifically for extreme street machines. Bridging the gap between our competition series units and our Super StreetFighter™ converters, we introduce the Ultimate StreetFighter™ series.

 

Triple Tested Quality

TCI® strives to produce the best torque converters in the industry. Part of the process involves ensuring that each unit is built to spec. Regardless of what category or price level it may fall into, every TCI® torque converter is Triple Tested during assembly.

Once all the prep work on the component parts has been completed, the impeller is welded to the front cover. Immediately following this process, a pair of dial indicators are employed on a rotating table to verify that the impeller body and pump drive hub remain true.

Each unit is then pressurized and subjected to a leak test to confirm the integrity of all the weld seams. Lastly, each unit is computer balanced to reduce annoying and potentially damaging drivetrain vibrations that would occur from an unbalanced torque converter. That's Triple Tested so you can be confident you're getting a torque converter that's ready to roll.
