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.

TCI Drag Racing Converter 10", 1998-Up LS 4L60E, 4500 Stall Speed
7-10 business days to build
TCI Competition torque converters are proven race winners and an excellent choice for stock and Super Stock cars. They work well with both big and small blocks, producing power between 4,500 and 7,000 rpm. You'll maintain engine rpm between shifts with their efficient design, and gain improved reliability with an oversize caged bearing supporting a new cast steel stator. ETs are more consistent and reaction times faster as a result of a stronger housing, which resists flexing and ballooning.
Designed with the street/strip application 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 Street Fighter lets you take advantage of horsepower gains found in higher RPM ranges.

4L60E Super Street Fighter Torque Converter with Billet Cover, 3500 Stall Speed, 2.7:1 STR
7-10 business days to build
TCI StreetFighter converters are completely remanufactured with furnace-brazed fins, needle bearings, and a flame-hardened hub. StreetFighter converters will give you about a 3,000 to 3,500 rpm stall speed. They're recommended for use on high-compression street/strip engines and higher performance cars and are used on some of the fastest street machines the world over.
