Description

Your '68-'69 Firebird deserves a transmission that matches its performance potential. This complete TREMEC Magnum conversion eliminates the guesswork of piecing together a six-speed swap, delivering 700 lb-ft of torque capacity with double overdrive ratios that drop highway RPMs while maintaining aggressive acceleration. The Magnum architecture represents TREMEC's most advanced 6-speed design -- the aftermarket version of the TR-6060 found in factory muscle cars like the Dodge Challenger and Chevrolet Camaro.

Unlike cobbled-together swaps, this package addresses every component needed for a clean installation in your first-generation Firebird. The Magnum uses a GM-style bellhousing bolt pattern, and the shifter position is retained for that stock look and feel -- little to no tunnel modifications are required. The transmission features 4616 chromoly gears and shafts with a one-piece countershaft, increased face-width on all gears, and enhanced webbing in the main case for maximum strength.

The package configurator walks you through transmission options (close ratio 2.66 first gear or wide ratio 2.97 first gear), clutch combinations, hydraulic systems, crossmembers, and driveline components. Whether you're running a numbers-matching 350 or a built 455, the system helps match components to your power level and driving style. Choose from single-disc or twin-disc clutch assemblies, mechanical or hydraulic release systems, and a variety of shift levers and knobs to complete your build.

Every MDL package component is selected for proven compatibility with 1968-1969 Firebird chassis requirements. From bellhousing to crossmember, clutch hydraulics to speedometer adapters, you're getting components that work together rather than hoping aftermarket parts play nice. The transmission takes TREMEC HP-MTF, Synchromesh, or Dexron III ATF. Complete installation support and lifetime technical assistance ensure your conversion goes smoothly.
