OUR SERVICES
Complete heavy-duty repairs under one roof. All kinds of repairs and maintenance for
trucks, trailers, and cars.
Air brake systems, ABS faults, and hydraulic brake issues all get fixed by our certified technicians. We diagnose the problem accurately first. Then we repair it using commercial-grade parts. Every job ends with a full safety test before your truck leaves. Fleet clients get priority scheduling on every brake repair we handle.
We repair and replace tires on semi-trailers, transport trucks, and heavy-duty rigs. Our team stocks commercial-grade tires for fast turnaround. When a tire fails on the road, our mobile service gets to you fast. We assess every tire before repairing it, and recommend replacement only when it is genuinely needed.
Our technicians diagnose diesel engine issues using proper testing equipment. We handle everything from fuel injector faults to full engine overhauls. Every repair is tested under load before your truck returns to service. Fleet operators trust us for scheduled diesel maintenance that prevents costly breakdowns.
We diagnose gearbox and drivetrain issues before recommending any repair. Our team handles clutch repair, gearbox rebuilds, and full transmission replacements. Every job uses commercial-grade parts built for heavy load. We give you a clear estimate before any transmission work begins on your vehicle.
Leaf springs, air suspension, shocks, and axle alignment all fall under our suspension repair services. We inspect the full system first. Then we repair what your truck or trailer actually needs to stay road-safe. Every job ends with alignment checks to help you pass DOT inspection.
Wiring faults, ECM issues, and sensor malfunctions get traced using proper diagnostic equipment. We work through the system methodically. This means we fix the real fault, not just the symptom that showed up first. Every electrical repair is tested fully before your vehicle is cleared.
We service engine oil, transmission fluid, brake fluid, and hydraulic fluid for commercial fleets. Every fluid is checked for contamination and condition. Scheduled fluid maintenance prevents the breakdowns that come from skipped service. Fleet clients get maintenance plans built around their routes.
We build custom maintenance programs around your fleet’s routes and usage. Fleet clients get priority scheduling and simplified fleet billing. Every plan is designed to keep your vehicles road-ready. Account-based tracking keeps you informed after every scheduled service visit.
Breakdowns do not wait for a convenient time, and neither do we. Our technicians respond fast with mobile diagnostics. We handle emergency repairs for trucks, trailers, and cars across Montreal. Fleet clients get priority response to keep downtime as short as possible.
Vehicles We Service
We service engine oil, transmission fluid, brake fluid, and power steering fluid for passenger cars. Every fluid is matched to your vehicle’s specifications. Fresh fluids protect your engine and keep your car running the way it should on every drive.
Battery issues, wiring faults, and computer diagnostics all get handled by technicians who work on car electrical systems every day. We trace the real cause first. Then we repair it correctly, so the same fault does not come back a few weeks later.
