Winters 60100 Falcon Late Model Two-Speed Transmission, 18 Spline

The Winters 60100 Falcon is a 2-speed manual racing transmission built for circle track competition, combining an 18-spline input shaft, a 600 lb-ft torque rating, and a direct 1:1 high gear in a lightweight aluminum case.

What it's for

This is a dedicated racing gearbox, not a street unit: it runs an integral hydraulic wet clutch, two forward gears plus neutral and reverse, and is sized to support engines up to roughly 900 horsepower. The maker lists this as suited to a range of circle track classes, from entry-level stock cars through open-wheel modifieds and higher-horsepower race cars running custom chassis.

What to check before ordering

The case dimensions are comparable to Muncie and T-10 transmissions, which helps with installation, but a bellhousing, shifter, and yoke are not included, so you will need a compatible racing bellhousing, a linkage-style shifter, a hydraulic clutch pedal assembly, and a 27-spline slip yoke on hand. The included crank coupler is sized for 1986-up Chevrolet small block engines with an 18-spline connection, and the recommended fluid is Type F automatic transmission fluid.

What's in the package

Along with the transmission itself, the package includes the 18-spline crank coupler, a bellhousing filler shim, the internal hydraulic clutch assembly, installation hardware, and manufacturer documentation. Gear ratios run 2.40:1 in first and a direct 1.00:1 in second, with reverse included.

Common questions

Does it need special gear oil? No, the recommended fluid is Type F automatic transmission fluid rather than a gear oil.

Is a bellhousing included? No, you will need a compatible racing bellhousing separately.

What's the warranty? It carries a 1-year limited warranty against defects in materials and workmanship, provided the unit is installed correctly and run under normal racing use.
