Allison Transmission has begun production of its 1000 Series and 2000 Series automatic transmissions ahead of the 2019 Chevrolet medium-duty truck launch. The two transmissions have been specially developed for the 2019 Silverado 4500HD, Silverado 5500HD and Silverado 6500HD.
The company announced the production start in a Monday release and said both the company and Chevrolet have worked closely to develop the transmissions to meet the medium-duty truck’s needs. Each Allison Transmission will be paired with a Duramax V8 engine, a combination the market has come to know for decades.
The 1000 and 2000 Series automatic gearboxes will include features such as power take-off (PTO), double overdrive, the company’s patented Continuous Power Technology and efficient FuelSense systems. PTO will give customers the ability to operate auxiliary equipment, which is necessary for dump trucks, water pumps, tow truck winches and more. The company will also offer motorhome and emergency vehicle transmission applications to give these vehicles the ability to speed up quicker and integrate body and pumping equipment.
Each transmission will feature six close-ratio speeds and have been optimized to work with the Duramax V8 engine’s 350 horsepower and 700 pound-feet of torque.
The new 2019 Silverado 4500HD, Silverado 5500HD and Silverado 6500HD mark Chevrolet’s return to the Class 4, 5 and 6 medium-duty conventional cab segments. Pricing will start a $48,465 for a 4500HD regular cab, which includes a mandatory $1,195 destination fee. Pricing for a 5500HD starts at $51,500 and climbs to $54,575 for a 6500HD medium-duty truck.
Production of the Chevrolet medium-duty trucks will take place at Navistar’s production facility in Ohio later this year.

What’s the difference between the 1000 that is currently used in the HD’s and the new 2000?
The 2000 series is not new and was introduced around the same time as the 1000 series back around 1999 or 2000. The main difference is the gear ratio spread. The 2000 series uses numerically higher gear ratios to produce greater torque for moving larger vehicles, but of course at a sacrifice of top speed.
I don’t know the difference, but the 1000 was used in the 4500 Kodiak with the Duramax, and the 2000 series was used in the Kodiak 5500, and 6500 with the Duramax. I own a 2004 Kodiak 5500 with the 5 speed Allison.
