Equipped with two input shafts (one inside the other), torque interruptions are imperceptible during gear shifting. In fact its gear-shifting technology is so rapid the “head-bob” is eliminated.

With half the gears on one main shaft and half on the other and a cluster between them, the dual clutch brings the two transmissions together. Odd number gears reside on one shaft, even number gears on the other. When shifting from one gear to the next the second gear is already pre-selected and the dual clutch operates in 200 milliseconds.

The valve body, pictured at the right of the clutch, contains a series of valves that control the fluid that assists in the gear shifting actuation and the clutch release.


For racing cars, TREMEC introduced their new Magnum XL to the heart of competition at the Detroit Grand Prix, June 1-2, 2013. Originally designed for the S197 Mustang, the Magnum XL features an extra long extension that not only delivers precise shifting but also extends the shift lever back to a more convenient location. The transmission is designed to eliminate the OEM two-piece driveshaft. The use of a one-piece aluminum replacement reduces the rotating mass by more than 20lbs. Moreover an SFI-approved burst-proof bell housing is supplied with the kit.

  1. I’m confused. Why would you need an old-fashioned shift lever at all? Just a selector for forward or reverse should work. Or is this different from the Dual Clutch transmissions where you flick a lever on one side of the steering wheel to upshift and another on the opposite side to downshift?

  2. Is there a dual clutch transmission that can be put into a 2006 Mustang GT?

    • Regarding your question… The short answer is no, there is not a DCT that can be put into a 2006 Mustang GT, or any other model year of anything for that matter. This is due largely to the level of powertrain integration required to make the product function properly. It is a very costly effort that, for now, remains the exclusive domain of OE manufacturers. At some point, we do hope to have a DCT product for the aftermarket that would be suitable for the type of retrofits often achieve with our conventional manual transmissions today. However, if I were to guess, optimistically that point is still a few years away.
