The 2020 Chevrolet Silverado HD debuted this week to some, uh, strong reactions.
But while many folks on the internet may not be a fan of the Heavy Duty Silverado’s exterior looks, at least the powertrain seems rock solid: a new gas engine, an available Duramax turbo diesel V8 with 910 lb-ft of torque and a new Allison 10-speed automatic transmission. What’s not to like about that?
There’s one interesting tidbit of information about the 2020 Silverado HD’s hardware you may not have heard yet, though. That new Allison 10-speed isn’t actually made by the familiar Indianapolis-based engineering firm. It will be built in-house by General Motors and simply features Allison branding. The transmission isn’t closely related to the 10-speed automatic found in the 2019 Silverado 1500, as far as we can tell, with General Motors describing the Allison-branded unit as “all-new.”
The only way to get a true Allison-built transmission in your Silverado is to opt for the new Silverado 4500, 5500 and 6500 medium-duty trucks. These monsters will feature an Allison-designed and built six-speed automatic transmission. The new six-speed was developed in conjunction with GM and is designed specifically for use in the gargantuan medium duty Chevys.
It’s not surprising that GM wanted Allison branding on the side of the 2020 Silverado HD. The company is the world’s largest purveyor of automatic transmissions for heavy duty and commercial vehicle applications and has been a mainstay on GM trucks since the 1950s. Chevy’s hard working HD customers have come to know and trust the Allison name and seeing the branding on the side of the truck might give them some reassurance that this new truck isn’t such a departure from older versions of the Silverado HD.
The 2020 Silverado HD will be built at GM’s Flint Assembly plant in Flint, Michigan and will be available in the United States, Canada and Mexico. Pricing has yet to be announced, but stay tuned to GM Authority for more 2020 Silverado HD news and information as it becomes available.
