Description

Ford 429/460 big block builds demand a transmission that can survive serious torque while delivering modern shift quality and highway drivability. This complete TREMEC Magnum 6-speed package solves that challenge with a comprehensive kit engineered specifically for Lima-series big blocks. Based heavily on the TR-6060 found in factory muscle cars like the Dodge Challenger, Viper, and Chevrolet Camaro, the Magnum combines TREMEC's current OEM technologies with the most popular features of the TKO 5-speed to create the smoothest shifting, strongest, and most versatile 6-speed aftermarket transmission TREMEC has ever produced.

The Magnum's internal upgrades over earlier T-56 designs are substantial. Significantly widened gear faces and 2-piece laser-beam welded gear construction allow for greater control of tooth angles, pitch, and alignment than traditional one-piece forgings. A one-piece countershaft with thicker journals replaces the torque-limited two-piece design found in earlier units, while spring-loaded ball-type synchronizer inserts and triple-cone synchronizers on gears 1-4 deliver incredibly short, low-effort shift throws with crisp engagement. The 85mm center distance and enhanced webbing in the main case provide the foundation for the 700 lb-ft torque rating.

The package includes your choice of transmission gear ratios, with both 2.66 close-ratio and 2.97 wide-ratio first gear options available. Wide-ratio gearing delivers strong off-the-line acceleration while deep overdrive ratios drop highway RPMs for improved fuel economy and reduced engine stress. The fully reversible TKO-style shifter offers multiple positioning options to optimize placement in your application, and built-in mid-shift provisions under the inspection cover allow simple conversions if needed. Dual speedometer pickups accommodate both mechanical and electronic applications.

This guided package builder walks you through selecting the transmission, Ford 429/460-specific bellhousing, flywheel (steel or aluminum), clutch assembly with hydraulic release, master cylinder kit, hydraulic lines, speedometer components, shift hardware, transmission mount, fluid, wiring harnesses, and driveshaft yoke. Every component is selected for proper fitment with your Ford big block. Tunnel modifications may be required depending on the vehicle. MDL's technical team is available to help you select the right parts for your project and budget.
