Description

Converting your '79-'93 Mustang to LS power demands a transmission that can match the torque and reliability of modern GM V8s. This comprehensive T56 Magnum package eliminates the guesswork and compatibility headaches of piecing together your manual transmission conversion. The Magnum's 700 lb-ft torque capacity handles everything from naturally aspirated 5.3L and 6.0L builds to supercharged and turbocharged LSX combinations, while dual overdrive ratios drop highway RPM significantly compared to four-speed automatics or older five-speeds.

Built on TREMEC's proven TR-6060 architecture, the Magnum combines OEM supercar technology with the most popular features of the TKO 5-speed. Gears feature substantially increased face widths and two-piece laser-beam welded construction for exceptional strength and precise tooth geometry. The one-piece countershaft resists distortion under high torque loads, and split-ring retainers maintain tighter tolerances than traditional snap rings. The result is incredibly short, low-effort shift throws with crisp, precise engagement - even under aggressive driving.

The package includes everything from transmission and bellhousing through hydraulic release bearing, clutch, flywheel, crossmember, and driveshaft - all pre-engineered for seamless Fox body integration with LS engines. Built-in mid-shift provisions under the inspection cover allow simple conversions if you later want to relocate the shifter. Our guided selection process walks you through gear ratios (2.66 close-ratio or 2.97 wide-ratio), clutch capacity, flywheel options, and hydraulic system configuration to match your specific build goals and budget.

Installation retains the factory shifter location for that stock appearance while requiring minimal tunnel modification. Every component is selected for proven compatibility and performance in Fox body LS swaps, backed by lifetime technical support and our concierge service to help you build it right the first time.
