Description

Converting your automatic-equipped '67-'68 Mustang or Cougar to a proper three-pedal driving experience requires more than just bolting in a transmission - it demands a complete, engineered drivetrain solution. This comprehensive TREMEC TKX conversion package delivers exactly that for Ford Modular 4.6L and 5.0L engines, transforming your classic into an engaging driver's car with modern five-speed performance.

The TREMEC TKX represents the latest evolution in aftermarket five-speed technology, designed from the ground up specifically for restomod applications. All gears and shafts are machined from special-grade steel (ASTM 4615) for increased torque-carrying capacity, while caged needle bearings in all gear positions and oversized gear widths maximize durability under hard use. The ribbed three-piece aluminum housing - main case, intermediate plate, and extension housing - provides exceptional structural stiffness while keeping NVH to a minimum. Multi-cone synchronizers paired with hybrid sintered bronze and carbon rings eliminate the notchy feel of older transmissions, enabling crisp shifts even at elevated RPM.

MDL's guided package selection walks you through every component choice, from bellhousing material and clutch configuration to hydraulic system components and driveline hardware. Whether you prioritize street comfort or weekend track sessions, we help you match every part to your build goals. The TKX's compact end-loaded case design specifically accommodates tight classic Mustang and Cougar tunnels, often requiring no floor modifications while maintaining the stock shifter position for that factory appearance.

Each package includes lifetime technical support and detailed installation guidance. Our team is available to provide concierge-level assistance, ensuring you select the right components for your project and budget. This is a fully customizable package - contact us for a complete quote tailored to your specific application.
