    *UPDATE* GM Files Patent for 7-Speed Dual Clutch Gearbox

    September 26th, 2013

    Patent Drawings published on September 19th reveal that General Motors has filed a patent for a 7-Speed Dual Clutch Transmission. While there has been talk about a conventional GM 8-Speed automatic for a while, a 7-Speed DCT could give GM an upmarket transmission to offer in premium products from Cadillac or the Chevrolet Corvette.

    At the moment, the 2014 Corvette Stingray will be shipping with a 6-speed auto when the buyer opts not to row his own, leading us to believe that this 7-Speed DCT could be offered in the Corvette in the future. We also speculate that with a couple of V-series Cadillacs on the way, the timing could be right for an introduction in one of them.

    Update: A reader points out that the output shaft in the above drawing is offset to the side of the transmission (label 16). This means it is highly unlikely that this is a rear wheel drive transmission, but instead is a front wheel drive, transversely mounted transmission.

    The 9-speeds that Jeep is using are a ZF design but built by Chrysler.

    My complaint with DCTs is their performance in traffic situations. I hope GM can address that with this transmission.

    The Ford one (Powershift or whatever it's called) used in Volvos is quite smooth even in traffic. Sampled it once in Sweden with a 1.6L diesel V60 wagon and with that engine I actually liked it better than the standard manual gearbox.

      I forgot this one from a visit to the State of New York.  This one was seen at Bear Mountain State Park. It looks like a Saturn Skye.  In my opinion, Saturn had the best looking minivan (Relay), the best looking compact (Aura), and the best looking two-seater (this) at the very end of those vehicle category runs for GM. Even if they shared mechanical underpinnings, these cars just looked a little bit cleaner than those of the others.

      Awesome specimen.    Sadly though, it is no longer available for sale.  Did the seller find a buyer?  At $48 000, it is relatively cheap to buy.  Does that mean muscle cars are going down in price?  Maybe its not a "numbers matching" 455.  Perhaps an aftermarket "upgrade".  It does have an Edelbrock stamp on the block which explains the "low" price of 48 thousand.   Either way, Id buy it.  Well...not now.  Owning a "vintage" muscle car would be #2 of my dreams and wishes.   Im on my way of realizing my #1  of dreams and wishes.  Owning a home (condo) on a Greek island.  My financials are almost there for that.  If #1 is not fullfilled, then #2 would happen.  But #1 looks to be right on track.  Only thing I will whine about is: Although I LOOOOVE Cragar SS wheels,  ESPECIALLY on muscle cars, I somehow disapprove of them on a 442.  The rich that support him are making even MORE money with him there so no...they will NOT listen. They do not care.  The others are racist bastards that as long as the ones they hate are in worse shape than they are, then they will allow trump to destroy the country.  It WILL take the rest of you to fight for your country.    To remove him FORCIBLY  and all those other cancerous shyteholes that have infected your country.
