Total TKO! Modern Driveline’s “Low-Profile” TKO Five-Speed Conversion for 1967-1973 Mustangs is a technical knockout
Modern Driveline was on top of the five-speed conversion game before anyone else with complete five-speed conversion kits and great technical support. These days, the Modern Driveline discussion moves quickly to five- and six-speed conversions for all Mustang generations and a host of other popular marques like Chevy Camaro, Corvette, and Tri-Fives, Cobra kit cars, trucks, Ford flathead V-8s, and even the Sunbeam Tiger.
Bruce Couture of Modern Driveline (MDL) invited us to his Caldwell, Idaho facility for a look at their latest innovation—the MDL “Low-Profile” TKO five-speed transmission for 1967-1973 small-block, 385-Series big-block, and FE-Series big-block Mustangs. What makes the “Low-Profile” TKO for classic Mustangs exciting is its no-nonsense fitment. This is a bolt-in swap from Modern Driveline without modifications to the transmission tunnel. That’s correct, no cutting. The Modern Driveline Low-Profile TKO will even fit the 1965-1966 Mustang with minor floor support modifications but is otherwise a simple fit that clears the tunnel and lines up nicely with the factory shifter opening.
