MTI Releases Sequential Transmission For Corvette And Camaro
If you’ve ever ridden a motorcycle you know a little something about wide-open throttle shifts with a sequential box. Sure you can’t skip gears, but ripping up and down through the box is a smile-inducing exercise and no-lift shifts are simply something else–downshifts also happen in an instant.
For those who’ve always wanted a sequential box like the ones in the ALMS cars, MTI has designed a kit for the Tremec T56 and T-6060 transmissions that slips into the original cases. It converts the conventional H-pattern shifts into a sequential unit and even 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.
Here’s the good stuff straight from the press release:
But this system’s real superiority is not just revealed in acceleration—its lightning fast no-lift up-shifting ability—but for track days and road racing, its downshifts through 6th, 5th, 4th, 3rd, & 2nd are all completed in less time than it takes to brake. Thus its startling down-shifting capability promotes greater vehicle stability under braking and corner entry.
It may appear MTI’s new sequential technology has suddenly burst upon the scene, but it hasn’t. In 2001, when the concept of track days had just started in the US, Corvette owners commented they were using only four of their six gears. At that time MTI’s Reece Cox addressed the issue by providing a special ring and pinion, which also improved acceleration.
Later he introduced a new close ratio gear, which allowed Corvette owners to use five of the six gears during track use. Then about four years ago, while still using the conventional H-pattern shift gate, MTI Racing introduced dog ring engagement to the Tremec T-56 gearbox casing. The forward ratios are as follows: 1st 2.437; 1.611; 1.228; 1.00; 0.875 and 6th 0.777.
By necessity the sequential system introduces a barrel arrangement that replaces the conventional H-pattern internals, while cleverly employing the same above-mentioned gears. Therefore all existing MTI Racing’s H-pattern dog boxes can be updated to sequential technology if desired.
Lastly, the firm’s electronic paddle shifting mechanism is in its final production stages.”
