Description

Ditch that tired automatic and put a proper 5-speed in your 1963-1972 C10 or C20. This complete conversion package delivers everything you need to swap from automatic to manual, giving you the engagement of a clutch pedal and the efficiency of a true overdrive fifth gear. The TREMEC TKX handles 600 lb-ft of torque and is rated for engine speeds up to 8,000 RPM with shifts at 7,500 RPM - more than enough headroom for built small blocks and big blocks alike.

TREMEC engineered the TKX from the ground up specifically for the aftermarket. The compact end-loading design creates a slimmer case profile that clears most transmission tunnels without cutting or hammering. Inside, oversized gear widths, caged needle bearings in all gear positions, and gaskets at all flanges deliver durability and eliminate fluid leaks. The three-piece ribbed aluminum housing provides structural stiffness while keeping weight down. Multi-cone synchronizers with sintered bronze and carbon hybrid rings produce smooth, notch-free shifts even at high RPM.

Automatic-equipped trucks require a bellhousing, flywheel, and complete clutch system - all included in this package. Choose from cast iron or aluminum bellhousings, steel or aluminum flywheels matched to your engine's balance and displacement, and clutch assemblies ranging from street-friendly organic setups to dual-disc units for serious power. The hydraulic clutch system eliminates Z-bar linkage hassles and provides consistent pedal feel with a sealed hydraulic release bearing.

MDL's package configurator walks you through every component selection - transmission ratio, bellhousing, clutch, hydraulics, shifter, crossmember, speedometer solution, and driveshaft yoke - ensuring proper fitment for your specific truck and engine combination. Need help deciding? Our concierge service puts you in direct contact with drivetrain specialists who can match components to your horsepower level, driving style, and budget.
