Is the 2020 Silverado HD’s Allison Transmission Not really an Allison?

When is an Allison not really an Allison? When it’s the new 10-speed Allison automatic destined for the all-new 2020 Chevrolet Silverado HD. That’s according to a new report from GM Authority.

Near the end of the Second World War, GM shifted the expertise of the Allison Experimental Company away from aircraft engine sand toward transmissions. Maybe that birth in making gearboxes for tanks helps explain how they’ve become nearly synonymous with heavy-duty automatic transmissions.

Since the introduction of the Duramax diesel to the Silverado and Sierra HDs in 2000, that automatic has worn an Allison badge proudly. Because it was an Allison 1000 automatic transmission.

The new HD trucks are getting what GM calls an all-new 10-speed auto. Thing is, Allison isn’t building an all-new 10-speed auto for pickups. GM Authority is reporting that the new trucks are getting an in-house built and designed 10-speed.

It’s just going to wear the badge because buyers know and love the name.

Expect more details on the all-new HD pickups as we near their launch date early next year.
