Description

Ditch the slushbox and put a proper stick in your big block B-Body. This complete TKX 5-speed conversion package delivers everything you need to swap your automatic for TREMEC's latest and most advanced 5-speed manual transmission. The TKX was designed from the ground up specifically for the aftermarket, with a compact case engineered to fit classic muscle car transmission tunnels without extensive floor pan surgery.

The engineering inside the TKX sets it apart from previous 5-speeds. Oversized gear widths, caged needle bearings in all gear positions, and tapered roller bearings on the input, output, and counter shafts deliver durability that matches the 600 lb-ft torque rating. The internal three-rail shift system with steel shift forks provides a robust, precise shift feel, while the multi-cone synchronizers with hybrid sintered bronze and carbon rings let you bang gears at up to 7,500 RPM without grinding. Ball detents on each shift rail improve shift feel and eliminate the notchy, vague gates that plagued earlier transmissions.

This package is fully customizable to your build. Choose wide ratio gearing (3.27 first) for street performance and towing capability, or close ratio (2.87 first) for applications where the engine makes strong low-end torque. Fifth gear overdrive options of 0.68, 0.72, or 0.81 let you dial in the perfect highway cruise RPM for your rear axle ratio and tire size. Select from single or twin-disc clutch kits, 130 or 143 tooth flywheel options, and multiple shifter configurations to get exactly the drivetrain setup your B-Body needs.

Fits all 1962-1979 Mopar B-Body vehicles equipped with big block B/RB engines, including Charger, Road Runner, GTX, Super Bee, Coronet, Satellite, and Belvedere. The cast aluminum bellhousing mates the big block to the Ford-pattern TKX and supports both 10.5-inch and 11-inch clutches with either 130 or 143 tooth flywheels. Hydraulic release bearing setup eliminates mechanical linkage hassles and delivers smooth, consistent clutch engagement with reduced pedal effort.
