    Allison vs. DCT

Nothing Makes The Grade Like An Allison

The dual clutch transmission (DCT) is the latest attempt to copy what an Allison already does… provide reliable, powerful performance for commercial-duty start-stop cycles. Developed to act like a fully automatic transmission, the DCT is unproven to stand up under the stress and strain of your fleet.

We Deliver 5% Better Fuel Economy Vs. Eaton Procision®

Certified, third-party fuel economy testing has proven the Allison 2500 Series™ automatic with FuelSense® technology beats the Eaton Procision® dual clutch transmission (DCT) by five percent.

  • The Facts Tell The Story

    Testing used the independent September 2015 revision of the SAE J1526 Fuel Consumption Test Procedure (Engineering Method). This testing method has been specifically developed for the trucking industry to analyze fuel consumption on two of the most common duty-cycles: the ARB Heavy-Duty Diesel Truck (HHDDT) cycle and the ARB Urban Dynamometer Driving Schedule (UDDS) cycle.

  • Higher Average Speeds for Increased Productivity

    An Allison fully automatic transmission with the torque converter accelerates quicker and delivers a higher average speed that translates into more trips and better productivity. Less downtime due to repairs also ensures your vehicles spend more time on the job.

    A dual clutch transmission (DCT) attempts to replicate the reliable, smooth power of a fully automatic transmission. A DCT does not multiply engine torque at start, and power is interrupted in top ranges, which decreases performance.

  • Driven To Perform

    • Continuous Power Technology™ increases performance and productivity in stop-and-go traffic, even with lower-rated engines.
    • Easy maintenance reduces downtime and costs with extended product life.
    • Helical gear design lowers noise emissions.
    • Greater safety and passenger comfort increase driver satisfaction.
    • Unmatched and proven reliability for your fleet.

  • The Power Of The Torque Converter

    Allison’s torque converter smoothly multiplies engine torque, delivering more power to the wheels. By multiplying the engine power, drivers get increased performance, faster acceleration and greater operational flexibility.

    Automatic vs. Dual Clutch Transmissions

    While the manual clutch pedal is gone in a dual clutch transmission (DCT), a clutch still facilitates the vehicle’s launch. Dual clutch transmissions (DCTs) do not benefit from engine torque multiplication which limits vehicle performance. Allison Automatics are unique because our patented torque converter experiences very little wear and our transmissions require only periodic fluid and filter changes to maintain peak performance.
