Live from TMC 2026 Nashville: Who Is Truly Speaking for the Drivers?

From March 16 to 19, 2026, the Technology & Maintenance Council (TMC) Annual Meeting kicked off in Nashville — North America's premier event for commercial vehicle maintenance professionals. This year's focus: intelligent diagnostics and fleet technology.

Exhibitors covered everything from deep engine data analysis to cloud-based fleet management, with a clear push toward integrated, full-system diagnostic solutions.

Exhibition Highlights

Multi-brand, full-system coverage has become the baseline expectation.

Cojali showcased Jaltest with full-system fault reading, data streams, and repair guidance across most heavy-duty brands. Snap-on (Booth 2312) combined NEXIQ Technologies' USB-Link hardware with Mitchell 1's TruckSeries repair platform into a seamless read-to-troubleshoot workflow. Bendix demonstrated ACom® diagnostic software alongside its RDU/TRDU remote units for braking and ADAS fault diagnosis.

The peripheral ecosystem was just as active: Diesel Laptops brought integrated diagnostic suites with aftertreatment regen and health reporting; ATD Diesel covered engine repair tooling; AEC focused on battery and charging diagnostics; ATEQ on TPMS. Cloud platforms from Connixt and Cox Fleet rounded out the fleet monitoring space.

What the Show Floor Revealed

The technology on display was impressive. But one pattern stood out: nearly all of it — complex software suites priced at $2,000 to $10,000+ — is built for fleet managers and shop technicians, not the drivers operating the trucks.

When a truck throws a derate on a remote interstate at midnight, the driver doesn't need a certified technician's workstation. They need to understand what's wrong and whether they can keep moving. That gap is why Proformance exists.

Our Philosophy

"A professional diagnostic tool — not just a regen tool — designed for drivers."

We took the diagnostic capability you'd find at a TMC exhibitor booth and rebuilt the experience around the person in the cab.

Designed for the Cab, Not the Shop

No manuals, no training weeks. Drivers understand what's wrong with their truck in minutes.

Beyond Regen

A forced regen is a temporary fix. Proformance gives you sensor data and fault traceability — so you know whether it's a bad sensor or a deeper issue before you call a shop.

Know Before You Go

Walk into any service bay with your own data. Fewer surprises, fewer unnecessary tows, less room to be overcharged.

The Response at TMC Said It All

The booth drew a steady flow of owner-operators, fleet managers, and independent technicians. The most common question: "Why hasn't anyone done this before?"
