 As much as it pains me to admit, the good old manual transmission is a slowly dying breed. But it only takes a couple launches in a dual clutch Porsche Turbo or a GT-R to not really miss it so much. Nowadays computers are just as involved in managing the transmission as the engine. So the ability to tune a transmission on an access port has become a big part of nearly every brand that we support. There's a long list of benefits and necessities, like customized shift schedules based on your driving situation, whether at the drag strip, the track or the street. Faster shifting for instant response and the fastest lap times. Improved clamping for high horsepower setups so your engine isn't limited by what your transmission can handle. And custom features like trans brake with bump and creep for drag racing. But maybe the biggest benefit is simply making the transmission smoother and more comfortable to live with. Ultimately, transmission tuning wasn't a part of Cobb 20 years ago, but as tech changes, so does Cobb. And we'll be ready for the next technological trend.
