General Motors To Take Allison Transmission Badging Off HD Trucks

general motors to take allison transmission badging off hd trucks

A licensing agreement between General Motors and Allison Transmissions is set to expire at the end of the year, and any Allison badges will be removed from unsolved trucks by the end of next June.

TFL Truck has the dirty details -- since 2020, GM has been putting "Allison branded" transmissions in Chevrolet and GMC heavy-duty trucks. The 10L1000 transmissions are built by GM and vetted by Allison.

While the badges are changing, the mechanicals aren't -- this transmission will remain in the HD trucks.

A badging story might seem like a nothingburger, but it matters for the supplier -- the trucks are rolling advertisements -- and if this author's anecdotal experiences with HD truck owners is representative, these customers care where the engine and transmission come from. Bragging rights are on the line in this fiercely loyal segment.

Tim Healey grew up around the auto-parts business and has always had a love for cars — his parents joke his first word was “‘Vette”. Despite this, he wanted to pursue a career in sports writing but he ended up falling semi-accidentally into the automotive-journalism industry, first at Consumer Guide Automotive and later at Web2Carz.com. He also worked as an industry analyst at Mintel Group and freelanced for About.com, CarFax, Vehix.com, High Gear Media, Torque News, FutureCar.com, Cars.com, among others, and of course Vertical Scope sites such as AutoGuide.com, Off-Road.com, and HybridCars.com. He’s an urbanite and as such, doesn’t need a daily driver, but if he had one, it would be compact, sporty, and have a manual transmission.

Did Jack Baruth bed the Allison in question and write 12 articles passively chronicling the escapade?

""The 10L1000 transmissions are built by GM and vetted by Allison"" .. ewww for tranny? your not losing anything killing the branding

The term "10L1000" refers to the Allison 10L1000 10-speed automatic transmission, used in 2020 and newer heavy-duty GM Silverado and Sierra trucks with the Duramax 6.6L diesel engine. It is a heavily modified version of a jointly developed Ford/GM 10-speed platform, engineered by Ford with Allison branding and designed to handle increased torque and offer better fuel economy compared to its predecessor, the 6-speed Allison 1000.

The Allison product that ought to be in these trucks is a scaled-down version of this. It works amazingly in use cases far more brutal than anything a pickup truck is ever subjected to. The agency I used to work for recently retired a fleet equipped with the first generation of the system after 20 years and nearly a million city miles each, with very few system failures.

Jkross22 "It’s that manufacturers have undermined the very concept of ownership by building de facto backdoors into connected products that now make up a majority of what’s on the market."Matt, you buried the lead. It's not just a privacy problem. Per Rossmann.... if you buy a product that relies on an internet connection to work, do you really own it or are you just making monthly installments in perpetuity until the product has a catastrophic failure and you have to buy a new one?Speaking of catastrophically failing products, Samsung is pushing ads to their refrigerators with screens.... The fridges that are $3.5k+. Nothing Phone is experimenting with sending ads to the people that bought their cell phones and making the ad the home screen. Google is cutting connected support for their Gen 1/2 thermostats so that they will no longer be accessible remotely. The appetite of companies to invade our privacy and to monetize us instead of innovating is endless. I know I'm not alone when I say the best car is one without a screen. If you can't avoid that, try to get one with a 3g radio. Good luck hacking those.
28-Cars-Later “1. The Industrial Revolution and its consequences have been a disaster for the human race. They have greatly increased the life-expectancy of those of us who live in “advanced” countries, but they have destabilized society, have made life unfulfilling, have subjected human beings to indignities, have led to widespread psychological suffering (in the Third World to physical suffering as well) and have inflicted severe damage on the natural world. The continued development of technology will worsen the situation. It will certainly subject human beings to greater indignities and inflict greater damage on the natural world, it will probably lead to greater social disruption and psychological suffering, and it may lead to increased physical suffering even in “advanced” countries....It would be better to dump the whole stinking system and take the consequences”― Theodore J. Kaczynski, Ph.D., Industrial Society and Its Future, 1995.
FreedMike "Automotive connectivity has clearly been a net negative for the end user..."Really? Here's a list of all the net negatives for me:1) Instead of lugging around a road atlas or smaller maps that do nothing but distract me from driving, and don't tell me where to go once I've reached Point B, I can now just ask my car's navigation system to navigate me there. It'll even tell me how long it will take given current traffic conditions. 2) Instead of lugging around a box of a dozen or so cassette tapes that do nothing but distract me from driving, I can now just punch up a virtually endless library of music, podcasts, or audiobooks on the screen, push a button, and play them. 3) I can tell my car, "call (insert name here)" and the call is made without taking my hands off the wheel.4) I can tell my car, "text (insert name here)" and the system takes my dictation, sends me the text, and reads off any replies. 5) I can order up food on my screen, show up at the restaurant, and they'll have it waiting for me. 6) I can pull up a weather map that allows me to see things like hailstorms in my path. 7) If I'm in trouble, I can push a "SOS" button and help will be sent. 8) Using my phone, I can locate my car on a map and navigate to it on foot, and tell it to turn on the heat, A/C, or defrosters.None of these are benefits? Sorry, not sorry...I like them all. Why wouldn't I? Consumers clearly also like this stuff, and if they didn't, none of it would be included in cars. Now, maybe Matt doesn't find these to be beneficial. Fair enough! But he should not declare these things as a "net negative" for the rest of us. That's presumption. So...given all that, what's the answer here? Matt seems to think the answer is to "unplug" and go back to paper maps, boxes of music, and all that. Again, if that's Matt's bag, then fair enough. I mean, I've been there, and honestly, I don't want to go back, but if that's his bag, then go with God, I guess. But this isn't the solution for everyone, and saying otherwise is presumption. Here's a solution that DOES work for everyone: instead of throwing the baby out with the bathwater, clean the bathwater. You do that very, very simply: require clear, easy-to-understand disclosure of data sharing that happens as the result of all these connected services, and an equally clear, easy-to-understand method for opting out of said data sharing. That works better than turning the clock back to those thrilling days of 1990 when you had to refer to handwritten notes to get you to your date's house, or ripping SIM cards out of your car.
