Description

Automatic transmissions waste power and eliminate driver control. This complete conversion package transforms your '69-'70 Mustang or Cougar from automatic-equipped to a full TREMEC T56 Magnum 6-speed manual, delivering the double overdrive gearing and 700 lb-ft torque capacity that Ford FE big blocks demand. Every component is selected specifically for Ford FE applications in first-generation Mustangs, from the bellhousing to the clutch system to the driveshaft yoke.

The T56 Magnum represents the pinnacle of TREMEC's aftermarket transmission engineering. Based heavily on the OEM TR-6060 found in modern Dodge Challengers, Vipers, and Chevrolet Camaros, the Magnum combines current supercar technology with the most popular features of the TKO 5-speed. Forged gears with laser-beam welded engagement plates provide precise tooth control and positive shift stops, while the one-piece countershaft features thicker journals and widened gear faces for maximum durability under hard use. Spring-loaded ball-type detents replace failure-prone stamped keys, delivering short, smooth shifts even at high RPM. Triple cone synchronizers on gears 1-4 and double cone synchronizers on 5-6 enable confident, crisp engagement throughout the range.

The Magnum's larger case requires tunnel modifications in '69-'70 Mustangs. The included sheet metal tunnel extension attaches to your existing floor pan for proper clearance. Hydraulic clutch actuation eliminates mechanical linkage complexity while providing consistent pedal feel and reduced effort. The guided selection process walks you through transmission gear ratios, clutch choices (single or twin disc), shifter options, speedometer solutions, and driveline components to build the exact combination your project demands.

This package addresses every aspect of the swap: from the clutch pedal assembly that replaces your automatic brake pedal, to the crossmember and transmission mount, to reverse lockout controllers and wiring harnesses. Multiple shifter lever and knob options let you match your interior. Speedometer cable and gear combinations maintain accurate speed readings, while electronic sensor harnesses provide modern instrumentation compatibility.
