FTI 9.5in 700R4/4L60(Early) Economy Lock-Up Street Racer Series - 27 Spline - 3200 Stall

If you're looking to get more out of your classic rear-wheel-drive car, especially one equipped with a 2004R or an early 700R4 transmission, a torque converter is a key component to consider. This FTI Performance lock-up torque converter is built for street performance, offering a 3200 RPM stall speed that helps your engine get into its power band quicker off the line. It's designed with a 9.5-inch diameter and a 27-spline input, making it a solid option for a wide range of vehicles, including models like the Chevrolet Caprice, Buick Regal, and Oldsmobile Cutlass Supreme.

This converter is part of FTI's Economy Street Racer series, meaning it balances performance gains with a well-built construction suitable for regular driving and spirited use. The lock-up feature is important for highway cruising, as it engages at higher speeds to create a direct mechanical connection, improving fuel efficiency and reducing heat buildup compared to non-lock-up converters. The 3200 stall speed is a notable increase over stock, providing that extra bit of RPM needed for quicker acceleration, especially when paired with a performance camshaft or rear-end gearing. It’s a well-made unit designed to handle the demands of street driving while offering a tangible improvement in your vehicle's responsiveness.

When installing a torque converter, it's crucial to ensure proper engagement with the transmission's input shaft and pump. Always refer to the transmission and converter manufacturer's instructions to confirm correct installation procedures, including checking for the proper seating of the converter onto the transmission pump drive lugs. This ensures the converter is fully engaged, preventing damage to both the converter and the transmission during operation. This FTI converter is a direct fit for many GM rear-wheel-drive applications from the 1980s and early 1990s.
