    2015 Chevrolet, GMC Trucks and SUVs Equipped With 6.2L V8 Get An Eight-Speed

      Eight-Speeds Come To Certain Chevrolet and GMC Trucks


    General Motors announced today that certain 2015 Chevrolet and GMC trucks and SUVs will trade in their six-speed automatic for an eight-speed automatic. Those models include,

    • Chevrolet Silverado
    • GMC Sierra
    • GMC Yukon Denali/Yukon XL Denali

    The catch is that all of these models must have the 6.2L V8 to get the eight-speed.

    Automobile Magazine reports that the Cadillac Escalade is also line to get the eight-speed transmission in the near future.

    GM says the new eight-speed is about the same weight as the outgoing six-speed, and features a wider gear spread which allows for more torque to be available in first gear.

    Other details such as fuel economy numbers and technical bits will released closer to the production date in the fourth quarter.

    2015 Chevrolet and GMC Pickups, SUVs to Offer Eight-Speed Transmission

    DETROIT – Chevrolet and GMC have confirmed a new eight-speed automatic transmission will be standard on 2015 Chevrolet Silverado, GMC Sierra and GMC Yukon Denali/Yukon XL Denali models equipped with the 6.2L EcoTec3 V-8.

    The GM-developed Hydra-Matic 8L90 eight-speed is approximately the same size and weight as the Hydra-Matic 6L80 six-speed automatic. Its 7.0 overall gear ratio spread is wider than GM’s six-speed automatic transmissions, providing a numerically higher first gear ratio to help drivers start off more confidently with a heavy load or when trailering. The 8L90 also enables numerically lower rear axle ratios, which reduce engine rpm on the highway.

    With 420 horsepower and 460 lb.-ft. of torque, the 6.2L EcoTec3 V-8 is the most powerful engine offered in any light-duty pickup, and offers a maximum available trailer rating of 12,000 pounds, based on SAE J2807 Recommended Practices. As with other EcoTec3 engines, it seamlessly switches to four-cylinder operation under lighter loads to improve fuel economy.

    Additional technical details and the EPA estimated fuel economy will be announced closer to the start of production in the fourth quarter of 2014.

    This is EXCITEMENT! It also tells me to hold off as I will see a decent change in MPG with the 8 spd Transmission in the SUV's and trucks. Sooner rather than later would be good as would the Diesel motor for the product line of trucks and SUV's

    What is with this slow roll-out with transmissions?  I understand they want it to be right, no warranty issues, etc., but they seemingly do this every time they bring out a new trans in the trucks.  This should be out ASAP in everything from Colorado to HD3500.

    I'm wondering the same thing ocn.

     

     

    That is good news, but why put it in a pick up and leave Cadillac with a 6-speed on most cars?  I assume this is the Aisin unit and not GM's own?

     

    No. It's GM's Hydra-Matic 8L90 transmission.

    • Since online stories seem to change, I am copy and pasting the instructions here: Uninstall the Copilot app The first thing you should do is uninstall the Copilot app. This is a Windows app and can be uninstalled like any other Windows app. There are a few ways to do this, and we’ll outline two of them. The fast way Hit the Windows Key to open your search and type in Copilot. Right-click the app with your mouse and select Uninstall. A window will pop up asking you to confirm. Do so. The app will be uninstalled. The harder way Open the Settings on your Windows PC. Navigate to Apps and then Installed apps. Find Copilot on your list of installed apps. Click the three-dot button on the right side and click Uninstall. For all intents and purposes, Copilot will cease to function on your PC after uninstalling the app, and you can go about your life in peace. Disable Copilot on a Windows PC Once the official app is uninstalled, there’s no real reason to do anything further, but if you really hate AI, you can if you want to. Damn the man! In the interest of completeness, here’s how to disable Copilot on your PC. This method is doable in two ways. If you have Windows 11 Pro, you can do this through the Group Policy Editor, which is quite simple. Those who have Windows 11 Home have to go through the Registry Editor, which can be an intimidating and potentially dangerous process. Thus, proceed at your own risk. Disable Copilot through the Group Policy Editor Hit the Windows Key to open search and type in Edit group policy or gpedit.msc and open the setting that pops up. Once the Group Policy Editor is open, you’ll navigate to a setting in the left margin. The order is User configuration, then Administrative templates, click on Windows components, and then finally Windows Copilot. Double-click where it says Turn off Windows Copilot; a new window will open. In the window, click Enabled, then Apply, and then finally OK. Copilot will be disabled. This method only works for Windows 11 Pro and Enterprise. While it is possible to install and use Group Policy Editor on Windows 11 Home, it’s not worth the effort, as there's a better option: Disable Copilot through the Registry Editor Hit the Windows Key and type in regedit, and then open the Registry Editor. Navigate to HKEY_Current_User, then Software, then Policies. Once there, go to Microsoft and then Windows, and finally CurrentVersion. There, you’ll see an option called WindowsCopilot. Double-click the TurnOffWindowsCopilot and change the value from 0 to 1. Exit Registry Editor and reboot your PC. It’s a simple enough process if you're used to working in the Windows 11 backend, but you can mess up a lot of stuff in the Registry Editor if you're not. Thus, again, proceed with caution and don’t change any of the other values. In addition, not all versions of Windows will have this registry option. Voila, Copilot is as off as Copilot gets If you've followed our advice, Copilot will now be disabled (or uninstalled) on your Windows laptop or Chromebook. Since most of its functionality comes directly through the Copilot app, uninstalling the app gets you about 90 percent of the way there, which should be more than enough for most Windows users. Disabling it via the Group Policy Editor or the Registry Editor finishes the job, but without the app in the front, Copilot can’t really do much of anything anyway.
