What is the purpose of the Sportsman transbrake?

The Sportsman transbrake allows you to hold the vehicle stationary with the engine at full throttle before releasing the brake button, enabling consistent and powerful launches off the starting line. It's a popular feature for drag racing applications.

What makes the 300M input shaft and billet components important?

The 300M input shaft is a stronger material than stock, designed to handle higher torque loads without failing. Billet aluminum components, like the direct drum and forward clutch hub, are machined from solid blocks of aluminum, offering superior strength and rigidity compared to cast parts.

Does this transmission come with a torque converter?

The manufacturer's description does not specify if a torque converter is included. It is recommended to check the product details or contact the manufacturer for confirmation on what is included in the package.

Product Details

The 300M input shaft in this FTI Performance TH400 Level 4.5 transmission is a key component that handles significant torque, making it a solid choice for high-powered street cars, weekend bracket racers, and mud trucks. This transmission is built to handle up to 1100 horsepower, offering a robust upgrade over stock units for demanding applications.

Inside, you'll find a 34-element intermediate sprag for improved durability and a 4-clutch intermediate pack that contributes to its strength. The billet aluminum direct drum and billet forward clutch hub are notable upgrades that enhance reliability under stress. This unit also features performance clutches and steels, a high-flow pump for consistent operation, and a race-prepped stock case that's been reinforced. A deep aluminum pan helps with cooling and fluid capacity, while the heavy-duty intermediate retainer adds another layer of strength.

This transmission comes equipped with a Sportsman transbrake, allowing for consistent launch control at the drag strip. The full manual valve body with a reverse pattern gives the driver complete control over gear selection. It's designed as a bolt-on bell housing unit, simplifying installation into many popular chassis.
