Description

Converting your '72-'78 Torino from a tired automatic to a modern five-speed manual transforms both performance and driving experience. The TREMEC TKX was developed from the ground up specifically for the aftermarket - it's not a recycled OEM unit, but purpose-built for classic muscle car applications. With 600 lb-ft of torque capacity and the ability to shift at 7,500 RPM, this transmission handles serious power while delivering the precise, modern shift feel your Ford small block deserves.

The TKX's compact envelope was engineered to fit classic transmission tunnels without extensive floor surgery. Its end-loaded design and slimmer case profile clear obstacles that plagued earlier five-speeds, while maintaining the same case mounting and crossmember locations as the TKO - making this a straightforward upgrade path. The three-piece ribbed aluminum housing provides outstanding structural stiffness at just 99 pounds dry weight. All gears and shafts are manufactured from ASTM 4615 special-grade steel, while tapered roller bearings on input, output, and countershafts reduce noise and improve durability.

MDL's package approach eliminates the guesswork of component matching for your Torino build. Every transmission option comes with compatible bellhousing choices for Ford small block applications - 289, 302, or 351W. Clutch options range from street-friendly single-disc setups to heavy-duty configurations for modified engines. Hydraulic actuation packages include master cylinder, external slave cylinder, and all necessary lines for clean pedal feel without mechanical linkage hassles. Shifter options accommodate OEM-style positioning for that factory look and feel.

The transmission features superior shift-ability through multi-cone synchronizers and hybrid synchronizer rings made of sintered bronze and carbon fiber. Three shifter locations accommodate various interior configurations, and the included billet aluminum short-throw shifter isolates road noise while delivering clean, crisp shifts. With 2.7 quarts fluid capacity and mechanical plus electronic speedometer outputs, the TKX integrates seamlessly with both classic gauges and modern instrumentation. This package is designed for Torino owners who demand reliability, performance, and the engagement that only a manual transmission delivers.
