TCI StreetFighter Automatic Transmission Packages 111100P1

This package also targets 625 advertised horsepower on the Mopar bellhousing pattern, but its 10.000-inch torque converter is tuned to a lower 3,000 rpm flash stall than a similarly rated package nearby, a meaningful difference if you're matching converter behavior to your engine's power curve.

Why the stall speed matters

A lower stall speed generally suits an engine that makes usable torque further down the rev range, so weigh your specific combination before choosing a converter spec. The Hemi-style 7/16-20 inch converter bolts ship installed, and twelve quarts of fluid plus a dipstick round out the package, alongside the cooler that's already in place.

Driveline specifics

First gear is 2.45:1, and the tailshaft measures 18.375 inches off a 24-spline input, in a black-finished aluminum case with a deep chrome steel pan. There's no trans-brake, and it is not lockup compatible. The valve body is listed as automatic/manual, giving you both a standard Drive setting and manual control. Sold as a complete kit, with the converter, cooler, fluid, and dipstick already accounted for so there's less left to source before install day.

How is this different from the other 625 hp package here? Mainly the torque converter's stall speed, which runs lower on this particular version. Does it include fluid? Yes, 12 quarts ship with the kit, along with the dipstick to check it.
