700R4 Breakaway Torque Converter 27-Spline

The TCI 700R4 Breakaway Torque Converter 27-Spline (part number 242500) is a direct-fit stall converter designed for General Motors 700R4 and 200R4 automatic transmissions. This unit is engineered to enhance performance for street driving, light towing, and responsive off-line launches while maintaining drivability on the highway.

The converter features a stall range of 2200–2600 RPM, allowing it to hold engine RPM higher during acceleration before fluid coupling occurs. This results in improved throttle response and reduced bogging when pulling loads or launching from a stop. Additionally, it includes lockup functionality that mechanically connects the turbine to the impeller at highway speeds, enhancing fuel economy and minimizing heat buildup.

This torque converter is ideal for buyers looking to improve transmission response and reliability in older GM vehicles without needing to replace the gearbox. Its design ensures compatibility with 700R4 and 200R4 transmissions commonly found in full-size trucks, SUVs, and performance vehicles from the 1980s through early 2000s.
