Description

Transform your automatic B-body into a double-overdrive beast with this complete TREMEC Magnum conversion package. Designed specifically for 1962-1979 Mopar B-bodies equipped with big block V8 engines (383, 400, 426, 440), this kit replaces your sluggish automatic with a 700 lb-ft rated 6-speed manual that delivers both tire-shredding performance and highway-friendly fuel economy. Whether you are building a Charger, Coronet, Road Runner, GTX, Super Bee, Satellite, or Belvedere, this package provides everything needed for a complete drivetrain transformation.

The heart of the package is the TREMEC Magnum - the aftermarket version of the TR-6060 found in factory supercars like the Dodge Viper, Corvette ZR1, and Camaro ZL1. Wide-ratio variants feature a 2.97 first gear for strong acceleration combined with dual overdrives - 0.80 in 5th gear provides the perfect balance between torque multiplication and cruising comfort, while 0.63 in 6th gear delivers superior fuel economy at highway speeds. Triple-cone synchros on gears 1-4 and double-cone synchros on 5-6 and reverse provide smooth, effortless shifting even under heavy loads, and 4616 chromoly gears with one-piece countershaft construction handle extreme performance applications.

This is not a simple bolt-in swap - tunnel modifications are required due to the Magnum's larger case dimensions. MDL includes a sheet metal tunnel extension that attaches to your original floor pan, eliminating the guesswork. The guided package selection walks you through choosing the right transmission variant, flywheel balance (383/400, 426, or 440), clutch capacity, hydraulic release bearing, shifter style, and driveshaft yoke for your specific engine and power goals.

Every component is selected for maximum compatibility and performance. The package includes your choice of TREMEC Magnum transmission variants, billet aluminum bellhousing, steel flywheel matched to your engine balance, complete hydraulic clutch system with master cylinder and release bearing, transmission mount, speedometer provisions, wiring harnesses, and all necessary hardware. Professional installation recommended due to tunnel modifications and hydraulic system requirements. Contact MDL for concierge service to ensure proper part selection for your project and budget.
