About the Eaton Procision (Dual-Clutch, medium-duty)

The Eaton Procision was a 7-speed dual-clutch transmission (DCT) for Class 6-7 medium-duty trucks — Eaton's experiment with passenger-car DCT technology in commercial applications. Production ended 2020 as adoption was limited. The Procision was Eaton's bet that DCT smoothness + AMT-style automation could displace Allison automatics in medium-duty markets. Limited fleet adoption killed the platform — most Class 6-7 buyers continued to spec Allison automatics or stick with manuals.

Frequently Asked Questions

What is the Eaton Procision (Dual-Clutch, medium-duty)?

What trucks use the Eaton Procision (Dual-Clutch, medium-duty)?

The Eaton Procision (Dual-Clutch, medium-duty) is used in 2 truck models including Freightliner M2, International Truck MV Series. It's typically paired with Medium-duty (legacy) applications.

Is the Eaton Procision (Dual-Clutch, medium-duty) reliable?

Mixed track record. DCTs in heavy-duty service had issues with clutch wear and fluid degradation. Some fleets reported good experience; others had reliability complaints.

What's the difference between an AMT and a manual transmission?

Automated Manual Transmission (AMT) uses the same gearset as a manual but adds computer-controlled clutch and shifter — no clutch pedal, no manual shifting. Modern AMTs like Eaton Endurant, Detroit DT12, and Volvo I-Shift offer smooth shift quality and predictive shifting via GPS. Manual transmissions (Eaton Fuller 10/13/18-speed) require driver-controlled clutch and shifting — more driver effort but maximum control and proven reliability. Automatic transmissions (Allison) use a torque converter and clutch packs — smoothest operation but heavier and less fuel-efficient than AMTs for highway use.

How long does a Eaton Procision (Dual-Clutch, medium-duty) last?

Commercial truck transmissions typically last 500,000 to 1,500,000 miles depending on maintenance, application, and driver skill. Manual transmissions (Eaton Fuller) routinely cross 1.5M+ miles. AMTs (Endurant, DT12, I-Shift) typically last 700K-1.2M miles before major service. Automatics (Allison) often outlast the truck itself in vocational applications. Maintenance discipline matters most — clean fluid + filter at recommended intervals extends life dramatically.

Does the Eaton Procision (Dual-Clutch, medium-duty) affect truck resale value?

Transmission choice significantly affects truck resale. Cummins-paired AMTs (Endurant) and manual 18-speed Eaton Fullers command premium resale in owner-operator markets. Allison transmissions hold premium in vocational markets.
