FTI TH400 Transmission - Level 4 - 900HP - Reverse Pattern - Sportsman Transbrake - GM Ultrabell

The internal components of this FTI TH400 transmission are built to handle up to 900 horsepower, thanks to a Level 4 build. This transmission features a Sportsman transbrake, which is a popular choice for drag racing applications, allowing for a more consistent launch. The reverse pattern manual valve body means you shift through the gears in a reverse sequence (P-R-N-3-2-1), which is common in performance builds and helps prevent accidental shifts into drive. The integrated GM Ultrabell bellhousing makes installation straightforward on GM V8 engines.

This transmission is constructed with robust internals designed for high-stress environments. The Level 4 build signifies a significant upgrade over stock components, incorporating stronger clutches, improved bands, and a reinforced gearset to withstand the demands of powerful engines and aggressive driving. The transbrake system itself is a key performance feature, enabling the driver to hold the vehicle stationary against the torque converter at full throttle before releasing the brake for an immediate launch. This setup is ideal for drag strip use where reaction time and consistent starts are critical.

When installing this transmission, ensure you have the correct transmission fluid type recommended by FTI Performance. It's also a good idea to inspect your driveshaft and U-joints for any signs of wear, as the increased power and torque can put additional stress on these components. This transmission is a solid choice for anyone looking to significantly upgrade their drivetrain for performance applications, offering a well-built unit ready for serious action.
