Engine Diagnostics & Computer Scanning
Full OBD scanning across Cummins, Detroit Diesel, PACCAR, and International protocols. We read fault codes, run active tests, and trace intermittent electrical issues that other shops guess at.
Expert semi truck repair — mobile diesel mechanic and in-shop service. We diagnose fast, stock common parts, and get you rolling. Diesel engine repair, transmission, brakes, electrical, DOT inspection. Ringgold, GA — I-75 and I-24 corridor.
A check engine light comes on 200 miles from your delivery. Your APU quits working in July heat. The scale house flags you for a brake violation. Every one of these means lost miles, lost money, and growing stress. You need a shop that picks up the phone, tells you what's wrong in plain language, and doesn't hold your truck hostage while they wait on parts.
We've seen every version of this situation — the owner-operator running on a tight margin who can't afford two days of downtime, the fleet manager with three trucks out of service at once, the driver who just needs someone to shoot straight about whether this is a two-hour fix or a two-day fix. That's what we do.
Every repair follows the same systematic process — no shortcuts, no surprises.
You call us, tell us what's happening. We ask about symptoms, location, and urgency. If you're on the road, we decide if this needs mobile service or a tow to the shop.
We get your truck information, fleet card details if applicable, and schedule you in. Emergency walk-ins get priority during off-hours.
Full OBD scan across all protocols, visual inspection, and road test if needed. We identify the root cause — not just the symptom code.
We stock common diesel parts — filters, belts, brake components, air system parts, sensors. If we need to order, we're honest about the timeline. No bait-and-switch.
Depends on the job. Brake adjustment might be an hour. DPF cleaning could be half a day. Engine work might take longer. We tell you upfront and update you if anything changes.
Every repair gets a road test and quality check before we hand the keys back. We verify the original symptom is gone and nothing new showed up.
You get a complete invoice with parts, labor, and warranty terms. Fleet customers get digital copies sent to their maintenance department.
Our diesel technicians handle the full range of semi truck mechanical and electrical systems.
Full OBD scanning across Cummins, Detroit Diesel, PACCAR, and International protocols. We read fault codes, run active tests, and trace intermittent electrical issues that other shops guess at.
Clogged DPFs cause derates and eventually shut your engine down. We perform in-shop forced regenerations and full DPF cleaning. If the filter is beyond cleaning, we'll tell you before wasting money on a regen that won't hold.
Parasitic drains, no-start conditions, alternator failures, wiring harness damage, and aftermarket wiring issues. We trace circuits with proper diagnostic equipment rather than just replacing parts until something works.
Leaking water pumps, cracked hoses, thermostat failures, EGR cooler leaks, and radiator work. Overheating on I-75 in July can destroy an engine — we fix coolant issues before they escalate.
Full brake service including shoe replacement, drum resurfacing, slack adjuster replacement, air chamber service, and brake valve repair. DOT-compliant brake adjustments that pass the scale house.
Pre-trip-level inspections for trucks and trailers. We catch violations before the inspector does — lights, brakes, tires, air systems, fifth wheel, frame cracks. Complete documentation provided.
Hard shifting, slipping, grinding noises, clutch wear, driveshaft vibration, U-joint failure, and differential issues. We diagnose whether it's a simple adjustment or a major overhaul.
Air bag leaks, spring pack failures, kingpin wear, tie rod ends, steering gear issues, and alignment problems. A truck that pulls or bounces is a safety hazard and a tire killer.
A shop is only as good as its tools. Here's what backs up our technicians.
Multi-protocol scanners that communicate with every major engine platform: Cummins INSITE, Detroit Diesel DDDL, PACCAR ESA, International DLB. We don't guess — we read the data.
In-house DPF cleaning equipment that restores filter performance without shipping your filter out for a week. Same-day cleaning available for most applications.
Brake lathe for drum resurfacing, air system test benches, suspension tools, and a parts inventory of common wear items. Most brake jobs completed same day.
Every repair has a story. Here are scenarios our techs deal with regularly.
An owner-operator pulled in with a check engine light and a load pickup 6 hours away. Diagnostic scan showed a failing NOx sensor throwing the engine into derate. We had the sensor in stock, swapped it in 90 minutes, cleared the code, and ran a test drive. He made his load.
A fleet driver got flagged at the Ringgold weigh station for out-of-adjustment brakes and a cracked air line. The fleet manager called us. We dispatched a mobile unit to the truck stop, adjusted all brakes, replaced the air line, and the driver cleared re-inspection the same day.
A reefer trailer electrical failure threatened a full load of frozen goods. The driver found us at 11 PM. Our tech traced the issue to a corroded wiring harness connection at the nosebox, repaired the connection, and verified the reefer was holding temperature before the driver left.
We repair semis at our Ringgold, GA shop and dispatch mobile mechanics to your location across the I-75 and I-24 corridors.
We'll tell you what's wrong, what it costs, and how long it takes — no runaround. Mobile or in-shop.
