Performance enthusiasts often underestimate the critical role torque converters play in putting their expensive horsepower to the pavement. TCI® street/street rodder and street/strip converters are designed by experienced drivetrain engineers to provide a significant increase in performance on the street or at the strip. With a more efficient stall speed, faster acceleration and better mid-range power, your machine will get the rear wheel power it deserves.
Some special features of TCI® torque converters include furnace-brazed fins for reinforcement and durability as well as heat-treated sprag races for increased strength and life span. They also utilize bearings that increase thrust capacity and reduce drag, as well as turbine spline reinforcement welds for increased durability and a heat-treated steel hub that increases converter strength. TCI® employs a highly specialized production process that involves ensuring that each unit is built to spec. Regardless of category or price level in which a TCI® torque converters falls, rest assured that it has been Triple Tested during assembly.
Once all 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 is 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 weld seams. Last, each unit is computer balanced to reduce annoying and potentially damaging drivetrain vibrations that can occur from an unbalanced torque converter. That’s Triple Tested so that you can be confident you’re receiving a torque converter that’s perfect for your specific application.

The first step into serious high performance, the Breakaway® is a great torque converter for moderately modified street machines and weekend racers that are also used as daily drivers. It provides approximately 2400 to 2600 RPM flash stall without negatively affecting part throttle driving. Designed for both efficiency at highway cruising speeds and to launch hard at wide open throttle, the Breakaway® is a fantastic all-around torque converter featuring furnace-brazed fins, needle bearings, a hardened, pre-ground pump hub and computer balancing.
Beginning in 1978 for Chrysler and 1979 for American Motors, a lock-up torque converter was used with most transmissions. You cannot interchange a lock-up converter with a conventional non lock-up converter. The transmission input shaft and valve body used for lock-up applications are different. TCI® offers converters for these two styles of operation. When changing to an aftermarket torque converter, you may need to replace the OEM flexplate. TCI® Part #145200 and Part #145300 flexplates are both heavy-duty units required when using a 10", 9", 8" or 7" torque converter. In conjunction with the converter and flexplate, you will also need to use TCI® Part #146200 7/16"-20 converter bolts.
TCI® also has external balanced flexplates that must be used when replacing an OEM externally balanced converter with an aftermarket non-weighted converter. This combination will allow a neutral balance between the converter and the transmission that is a must when using aftermarket parts.
