Description

Transform your 1968 Camaro from automatic to five-speed manual with this expertly curated TKX conversion package. TREMEC designed the TKX case specifically for the narrow confines of classic GM A-body tunnels, eliminating the floor modifications that plagued earlier TKO swaps. The end-loaded design presents a cleaner, smoother, and shorter leading end portion compared to previous transmissions, providing the clearance your ’68 Camaro needs without cutting sheet metal.

The engineering behind the TKX delivers real-world performance benefits your small block deserves. Multi-cone synchronizers with hybrid sintered bronze and carbon rings enable smooth, positive shifts at up to 7,500 RPM—a significant improvement over older five-speed designs. All gears and shafts are machined from ASTM 4615 special-grade steel with oversized gear widths for increased torque capacity and extended service life. Caged needle bearings in all gear positions reduce end play, while the three-piece ribbed aluminum housing provides outstanding structural stiffness with minimal NVH.

The single overdrive fifth gear reduces highway RPM for improved fuel economy and quieter cruising, while the multiple first-gear and overdrive ratio options let you match the transmission to your engine’s powerband and intended use. Whether you’re building a weekend cruiser or a serious performer, there’s a TKX configuration that fits. The 31-spline output shaft accommodates 1310, 1330, or 1350 U-joint slip yokes for driveshaft compatibility.

This guided package selection walks you through every component needed for a complete conversion—transmission, bellhousing, clutch system, hydraulics, crossmember, shifter, and all supporting hardware. Every option is selected specifically for 1968 Camaro small block applications. Complete MDL conversion packages include lifetime technical support and an extended manufacturer warranty with a 1-year grace period. If you have questions at any point, MDL’s concierge service can help you select the right parts for your project and budget.
