Description

Ditch the slushbox and put yourself back in control. This comprehensive TKX conversion package transforms your 1969-1970 Mustang or Cougar from automatic to a razor-sharp 5-speed manual, delivering the engagement and performance these classic muscle cars deserve. The TREMEC TKX represents purpose-built aftermarket engineering - designed from the ground up specifically for restomod applications rather than adapted from OEM designs.

The TKX's compact, end-loaded architecture provides the slimmest 5-speed case on the market, fitting classic transmission tunnels with minimal modification. That streamlined design doesn't sacrifice strength - a three-piece ribbed aluminum housing (main case, intermediate plate, and extension housing) delivers outstanding structural stiffness while gaskets at all flanges eliminate leak points. Inside, all gears and shafts are machined from special-grade ASTM 4615 steel with oversized gear widths for increased torque capacity and durability under high-load shifts. Multi-cone synchronizers paired with hybrid sintered bronze and carbon synchronizer rings provide smooth, precise shifts even at high RPM - up to 7,500 RPM shift capability with 8,000 RPM engine speed rating.

Every MDL package is fully customizable through our guided selection system. Choose your TKX gear ratio configuration, bellhousing material, clutch system, flywheel type, hydraulic components, shifter positioning, crossmember, and driveline hardware. Whether you're building a boulevard cruiser or weekend track warrior, we'll configure the perfect drivetrain for your Ford small block V8. The single overdrive gear drops highway RPMs for reduced engine wear and improved fuel economy while the retained shifter position maintains that authentic cockpit feel.
