1962-1964 Chevy II & Nova TREMEC TKX & A41 4L60E Transmission Kits

Modernize the driving dynamics of your 1962-1964 Chevrolet Chevy II or Nova with our PerfectFit™ Transmission Kits. These early X-Bodies are famous for their lightweight style but hampered by tight transmission tunnels and dated factory gearboxes. We offer the industry’s most refined overdrive solutions: the streamlined TKX 5-Speed, specifically engineered for low-profile fitment, and our smooth-shifting A41 4L60E Electronic Automatic.
 

Our 1962-1964 X-Body kits are designed to provide a seamless fit into your classic chassis with minimal to no tunnel modifications, delivering significantly reduced cruising RPMs for comfortable highway travel. Each system arrives as a total solution, featuring all the high-quality components required for a professional installation that maintains your factory interior aesthetics and shifter location while providing modern, high-performance reliability.
