OUR SERVICES
Complete auto and diesel truck repair for personal vehicles, commercial fleets, and everything in between.
Diesel Truck Repair & Service
Finding a good diesel mechanic is hard these days. J & M specializes in diesel trucks of all sizes — from pickups to heavy commercial vehicles. We diagnose and fix issues other shops can't solve, and we keep fleets running on schedule.
Engine Diagnostics & Repair
From check engine lights to complex mechanical failures, our technicians use advanced diagnostic tools to find the root cause and fix it right the first time. We work on BMW, Honda, Escalade, and all makes and models.
Brake Service & Replacement
Your safety depends on reliable brakes. We inspect, repair, and replace brake pads, rotors, calipers, and lines. Most brake jobs completed the same day — often in just a couple of hours.
Transmission Repair
Automatic and manual transmission repair, fluid service, and full rebuilds. We diagnose slipping, rough shifts, and complete transmission failures on all vehicle types.
Electrical System Diagnostics
Modern vehicles have complex electrical systems. We diagnose and repair wiring issues, sensor failures, battery and alternator problems, and more — for both diesel and gas vehicles.
Fleet Vehicle Maintenance
Keep your commercial fleet on the road. We provide scheduled maintenance, emergency repairs, and priority service for fleet operators throughout Passaic County. Available even in snowstorms when it matters most.
