    *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.

      This isn't new.  I can't make a decision on buying a car, since I haven't made the even bigger decision to precede when and WHERE to buy a car. I've got a lot of points from my GM Card.  Never would I have thought the market would change so drastically after I last used its accumulation and would start accumulating again. So, if I were to buy a tide over used car to keep for a few years, then what?  All low mileage ... the last Buick Verano 2.4 L the last Chevy Impala 2.5 L the 2015 Malibu with Camaro rear lights 2.5 L the last Mercury Milan 4 cyl. the last Charger base 3.5 V6 Something else Low mileage "older" cars cost a bundle, IF it's a dealer that's selling them.

      EV Home Charging: The Good, The Bad, The Ugly

      By G. David Felt · Posted

      Been 1 year since I installed my home Level 2 charger and have to say, I have had zero problems with it. No issues from ChargePoint and still going strong. Total cost of home charging for the year to cover roughly 19,000 miles has been $ 757.00 based on the tracking that the ChargePoint app on my cell phone does.

      Much appreciated, thank you. That is crazy and sad that GM, Toyota, Nissan in this day and age have allowed sloppy manufacturing to happen. Demming and Drucker were right about needing to keep a close eye always on quality for long term success. I do not blame your friend and hope GM does right by him and all the others. I think a 10yr / 100,000 mile powertrain warranty is proper here.

      One of my best friends bought a 2024 Silverado Trail Boss with the 6.2 and he's not too stoked about it. He hasn't' had any issues thus far, but he's very skeptical about long-term ownership. He said there's a rumor that they'll extend the warranty to 10yr/100,000 and he'd be satisfied with that, but if they don't he certainly wouldn't want to own it past his OEM warranty. I don't blame him, either. It sucks because he said he planned to keep the truck for 10 years as it's kind of a do-all for his family and him. He doesn't want to have to trade it in after 5 years because he has a good chance of needing to replace the engine. GM needs to do right by all these owners.  https://www.caranddriver.com/news/a64611938/chevy-silverado-tahoe-cadillac-escalade-defective-v8-recall/ "General Motors is recalling 721K full-size trucks and SUVs with the 6.2-liter V-8, as the engine might be defective; a stop-sale has also been ordered. The recall list includes popular models such as the Cadillac Escalade, Chevy Silverado 1500, and GMC Yukon—all of which are 2021–2024 models. The problem stems from internal manufacturing defects, and vehicles must pass inspection or possibly require an engine replacement. "
