    *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.

      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.

      Idiot47 is nothing more than a mole controlled by Russia. Do not forget the pictures and video that was released by Russia of him and prostitutes in Russia as he was there with his wife to try and get Idiot Hotels. He is nothing more than a stool pigeon for Russia destroying America and any other system as they try to push their dictator control of the world. WE THE PEOPLE need to take back America, Impeach Idiot47 and his whole administration. Bring back Democracy, working in unison with the world, not an attempt to attack the world and the continued pardoning of criminals. The whole administration needs to be arrested and turned over to the Hague to stand trial for Crimes against Humanity.

      Do not forget that he also reignited his racist "why do we get immigrants from non-white countries and not from white countries" rhetoric. Oh...then there is the constant talk about war on his own citizens. Also, the constant attacks on Canada, the usa's most reliable and friedliest neighbour. Not to mention the  grifting and the corruption that allows his friends and family to gain billions of dollars financially from government coffers.  I have become NON-TOLERANT to ANY american entity.  I DESPISE maga, trailer trash and anything remotely connected to trump and/or the republican party. I HATE anything american that ALLOWS trump to continue on this path and I do NOT respect americans that allow this shyte to exist.   And many many MANY Canadians feel the same way. It is NOT just me...  It is, in the grand scheme of things, ALL of Canada that has this hatred for the usa.  And its not ONLY because of trump...   I as a Canadian, we Canadians DO have a dog in this fight as trump has THREATENED OUR nation politically, economically. His words ARE words of war and add insult to injury, some americans to this day do NOT understand the severity of it all.     Phoque trump Phoque the usa
