Description

Transform your 1968-69 Camaro or Firebird LS swap into a true dual-purpose performer with this customizable TREMEC T56 Magnum conversion package. The Magnum delivers a massive 700 lb-ft of torque capacity - nearly double the original T56 - while solving the RPM and fuel economy challenges of classic muscle car gearing. The double overdrive design drops highway RPM significantly compared to traditional 4-speeds, transforming your first-gen F-body into a comfortable highway cruiser without sacrificing stoplight-to-stoplight performance.

The Magnum represents the pinnacle of TREMEC's six-speed development, combining current OEM TR-6060 technologies with the most popular features of their legendary TKO 5-speed. Under the skin, substantially widened gear faces and two-piece laser-beam welded construction provide precise tooth angle control and positive stops to prevent over-travel on hard shifts. The one-piece countershaft with thicker journals eliminates the weak points of earlier two-piece T56 designs, while triple-cone synchronizers on gears 1-4 and double-cone synchronizers on 5th, 6th, and reverse deliver remarkably smooth, high-RPM shift capabilities with minimal effort.

This guided package builder walks you through every component selection - from transmission gear ratios (2.66 close ratio or 2.97 wide ratio) and bellhousing options to complete clutch systems, hydraulic release components, custom shifters with multiple handle and knob choices, and a purpose-built crossmember for the '68-'69 F-body chassis. Whether you're building a street/strip bruiser or a refined pro-touring machine, this package can be configured to match your specific LS engine combination and performance goals. The Magnum's shifter position maintains the factory location for authentic driving ergonomics, and minimal tunnel modifications keep the installation manageable.
