What is an Allison Transmission?

If you’re a fan of heavy-duty trucks to get work done on the farm or jobsite, you need a reliable pickup truck that can haul a lot of cargo without sacrificing fuel economy, power, and speed. A truck with an Allison transmission can deliver on those requirements.

Allison transmissions are some of the most durable and efficient transmissions in the world. More than 250 vehicle manufacturers all over the world, including General Motors, rely on Allison transmissions to make their heavy-duty vehicles operate at peak performance. 

Discover more information about these transmissions and why they’re so popular from the friendly staff at Buick GMC Brooksville. 

Who Makes Allison Transmissions?

James A. Allison founded Allison Transmissions back in 1915, and he helped pioneer modern American motorcars when he helped to construct the Indianapolis Motor Speedway and funded several racing teams (although he is not an ancestor of the famous NASCAR Allison family).

Today, Allison Transmissions touts itself as the world’s biggest designer, developer, manufacturer, and distributor of medium- and heavy-duty fully automatic transmissions and hybrid propulsion systems. The company even developed an electric hybrid motor in the 1960s, a full 30 years before they would go mainstream.

The company specializes in transmissions for distribution, refuse, construction, fire and emergency trucks, buses, motorhomes and recreational vehicles, off-highway vehicles and equipment for energy, mining, and construction applications, and defense vehicles such as tactical wheeled and tracked vehicles.

Allison transmissions are found in some heavy-duty trucks on American roads, but not all.

Are Allison Transmissions Good?

Absolutely! They are some of the most sophisticated, fuel-efficient, and powerful transmissions found in internal combustion engines. 

Studies and statistics have shown that:

• Trucks equipped with Allison transmissions use 5% less fuel
• Allison transmissions only need routine maintenance without a major overhaul
• Allison transmissions last longer than their competitors, giving trucks with these parts an advantage

Some GM trucks have an Allison transmission installed to make sure they run most efficiently, deliver power when needed, and last a long time.

Which Trucks Have an Allison Transmission?

If you want a quality vehicle with an Allison Transmission, the staff at Buick GMC Brooksville recommends the following:

• Chevy Silverado 2500HD: The Chevy Silverado 2500HD has had an Allison transmission as its powerplant since 2007. It’s no wonder you still see many older models of the Silverado on the road today.
• GMC Sierra HD: Every GMC Sierra HD model from 2020 and later has an Allison transmission inside the engine. These heavy-duty workhorses deliver power and efficiency at the jobsite and on your property.

There’s a reason why an Allison transmission is only in these two larger GM trucks: Allison transmissions are big. They need a special type of engine to fit within them, and these two GM vehicles fit the bill.
