By Ben Mozart –  Photos by Moore Good Ink: Reece Cox is a man who immerses himself in details. For nineteen years he has served Corvette and Camaro owners, supplying them primarily with race parts. In the early nineteen nineties, he functioned as crew chief at Morrison Motorsports, running the Mobil 1 Corvettes. Now he is introducing the world’s first sequential retrofit transmission for the Corvette and all others with front-mounted Tremec T-56 transmissions. The purpose of his new gearbox is simple: gear shifts are executed in 10 to 20 milliseconds. Camaro, Mustang, Viper—in fact, conversions for all front-mounted Tremec T-56 transmissions soon to follow Marietta GA: MTI Racing has pioneered the world’s first 6-speed sequential transmission for C5 and C6 Corvettes. Operating in the stock transmission casing, its chief purpose is to accomplish exceedingly fast no-lift clutchless shifting. A direct bolt-in dog-engagement transmission, the service will soon extend to Camaro, Mustang, and Viper—in fact all front-mounted Tremec T-56 and T-6060 transmissions. Using the original Tremec gear case, MTI converts the internals and the H-pattern shift mechanism to full sequential operation. Introduced initially for the Corvette, it maintains the original mating surfaces and operates with the original mountings, clutch, slave cylinder, and drive-shafts. Its two key advancements are its strength and most of all its shifting speeds. Shift times with the original equipment require about a second. With dog engagement shift times are reduced to 0.30 to 0.40sec, depending on shift lever ratio. But when accompanied by an electronic paddle-shift mechanism, this dog-engagement design will affect a shift in 10 to 20 milliseconds (100th to 200th of a second). But...
