You have to love the internet for the many glorious things that surface. Among them; a patent application by General Motors dated September 19th for a Seven Speed Dual Clutch Transmission (DCT), which was originally filed back in May.
The bad news: this drawing appears to be for a front-wheel-drive application with transverse mounting. If you recall the Wide Open Throttle interview with GM President Mark Reuss, DCT sounded implausible at least for the near-future on the Corvette.
The good news: this or another patent may also cover rear-wheel and all-wheel drive applications.
While it may be years before anything ever comes of this, it does seem odd that GM would carry over the 6L80E transmission to the 2014 Corvette just like it did on the C6 with the 4L60E (for one year only). With a 7-speed Tremec in the manual version, one would think that the 6L80E's days might be numbered. In which case, a 7-speed DCT would make a suitable replacement that would shift much faster using the manual controls than the 6L80E is capable. For those who don't know, unlike the 6L80E which is an automatic transmission with manual controls, DCT's are more akin to an automated manual transmission. GM's original design called for a dry dual-clutch setup, which was designed in a lower power application to improve fuel economy by 10%. The wet-clutch designs are not quite as efficient, but are usually required for higher torque applications–BMW, Mercedes, Bugati, etc.
While this patent may not be for a new Corvette transmission, it does at least give us a glimmer of hope that this sort of technology could soon find its way into GM vehicles. And at the same time, we can continue to wonder whether the 6L80E will continue to be the clutch-less tranny of choice or if GM has something else up its sleeve for the Corvette as well as the upcoming CTS-V and the as-yet-be-named full-size Cadillac sedan.
