Hear from Our Customers
You’re not paying for a tow. You’re not waiting three days for parts. You’re not dealing with shops that treat your breakdown like it’s their favor to you.
When Dr. Phil and our team show up, we come with the tools, the parts, and the expertise to fix your truck where it sits. Most jobs get handled in under an hour. You get a fair price upfront, the work gets done right the first time, and you’re back to making money instead of losing it.
That’s what happens when you call someone who’s been doing this for 40 years and has three PhD degrees in diesel engineering, drivetrains, and metal alloys. Not because he had to—because he wanted to be the best at what he does.
J&J Truck & Trailer Repair has been the go-to name for Gibraltar truckers for over four decades. When you’re broken down near I-75 and Telegraph Road, you’re not calling some distant corporate chain—you’re calling neighbors who understand what it means to be stranded in Michigan weather.
Dr. Phillip Marin didn’t just learn diesel repair on the job. He earned three PhD degrees in the exact fields that matter: Diesel Engineering, Drivetrains, and Metal Alloys. Our family business operates 24/7 because breakdowns don’t keep business hours, and Gibraltar’s position on the I-75 corridor means trucks need help at all hours.
This isn’t about being the cheapest option in town. It’s about being the option that gets you moving again without the runaround, the delays, or the surprises on your bill.
You call, we dispatch immediately. No phone tag, no “we’ll call you back,” no waiting to see if someone’s available. Our mobile units carry the diagnostic equipment and common parts for most repairs right on the truck.
We arrive and diagnose the problem first—not after we’ve already started taking things apart. You get a clear explanation of what’s wrong and what it’ll cost before any work begins. No surprises, no “while we’re in there” upcharges.
Most repairs happen on-site. Engine diagnostics, brake work, tire changes, electrical problems, air system repairs—we handle it where your truck sits. If you need a tow, we do that too, but most of the time you’re driving away under your own power. The whole process usually takes under an hour, and you’re back on schedule instead of sitting in some shop’s parking lot for days.

Every service call includes complete diagnostic work with professional-grade equipment. We don’t guess—we know what’s wrong before we start fixing it. Our mobile units stock the parts and tools for the most common semi truck problems, from fuel system issues to brake repairs to electrical diagnostics.
Gibraltar’s location puts you right in the heart of Michigan’s busiest freight corridor. Trucks here deal with everything from winter road salt eating brake lines to summer heat pushing cooling systems past their limits. We’ve seen every problem that I-75 and Telegraph Road can throw at a truck, and we stock accordingly.
You also get transparent pricing and real timelines. When we say 45 minutes, we mean 45 minutes. When we quote $800, that’s what you pay. And when we fix something, it stays fixed—because Dr. Phil’s reputation has been built on 40 years of trucks that don’t come back with the same problem twice.
Most of the time, we’re on scene within 30 minutes of your call. Gibraltar’s position right off I-75 means we can reach most breakdown locations quickly, whether you’re on the interstate, Telegraph Road, or anywhere in the surrounding area.
Our dispatch system immediately sends the closest available unit to your location. We don’t make you wait while we figure out who’s available or shuffle schedules around. When you call, someone’s already heading your way.
Keep in mind that response times can vary during severe weather or if we’re handling multiple emergencies, but we always give you a realistic timeframe upfront. No false promises, no leaving you wondering if help is actually coming.
Most common breakdowns can be handled right where your truck sits. Engine diagnostics and computer issues, brake repairs including air brake and ABS problems, electrical system failures, cooling system leaks, fuel system problems, and tire changes are all standard roadside repairs for us.
Our mobile units carry diagnostic computers that work with all major truck manufacturers, plus the tools and common parts for these repairs. Dr. Phil’s engineering background means we can handle complex problems that other roadside services might not even attempt.
The repairs we can’t do on-site are usually major internal engine work or transmission rebuilds—basically anything that requires lifting the cab or completely tearing down major components. But even then, we can often get you to a safe location or back to your home base instead of leaving you stranded.
Yes, we service all major semi truck manufacturers including Peterbilt, Kenworth, Freightliner, Volvo, Mack, International, and Western Star. Our diagnostic equipment works with all the major engine brands too—Caterpillar, Cummins, Detroit Diesel, Paccar, and Volvo engines.
Dr. Phil’s three PhD degrees in diesel engineering, drivetrains, and metal alloys mean he understands these systems at a fundamental level, not just how to follow repair manuals. Whether you’re running a brand new truck with all the latest emissions equipment or an older model with mechanical systems, we have the knowledge and tools to diagnose and fix the problem.
We also work on all types of trailers including dry vans, flatbeds, tankers, and refrigerated trailers. Reefer repairs are a specialty—we handle Thermo King, Carrier, and other major refrigeration systems.
Repair costs depend on what’s actually wrong with your truck, but we always give you the price upfront before starting any work. Simple fixes like jump starts or minor electrical issues might run $150-300. More involved repairs like brake work or engine diagnostics typically range from $400-1200 depending on parts needed.
What you won’t get from us are surprise charges, “diagnostic fees” that disappear into the final bill, or inflated labor rates because you’re broken down and don’t have other options. We’ve built our reputation on fair pricing, and that means more to us than squeezing every dollar out of an emergency situation.
We also don’t charge extra for after-hours or weekend service. A breakdown at 2 AM costs the same as one at 2 PM. The only variable is what’s actually wrong with your truck and what parts are needed to fix it.
Absolutely. We handle DOT inspection failures and can get your truck back into compliance quickly. Whether it’s brake adjustments, lighting problems, air leaks, or other safety issues that failed inspection, we can usually fix these on-site and get you the documentation you need.
Our experience with Michigan DOT requirements means we know exactly what inspectors are looking for and how to address common violations. We can also perform pre-trip inspections if you want to catch problems before they become roadside emergencies or inspection failures.
For more complex compliance issues involving emissions systems or electronic logging devices, we work with certified facilities to make sure everything is handled correctly. But for most basic DOT violations, we can get you legal and back on the road the same day.
First, get your truck as far off the travel lanes as safely possible. If you can reach an exit or rest area, that’s ideal. If not, get onto the shoulder and activate your hazard lights immediately. Set up your warning triangles at the proper distances—this is crucial for your safety and required by law.
Stay with your truck but stay alert to traffic. Don’t stand behind or beside your vehicle where other drivers might not see you. If you’re on I-75 or another busy highway, consider staying inside the cab until help arrives, especially in bad weather or low visibility conditions.
Call us as soon as you’re safely positioned and have your warning devices set up. The sooner we know where you are and what’s wrong, the faster we can get the right equipment and parts to your location. And don’t worry about describing the problem perfectly—we’ll diagnose it properly when we get there.
