Frustrated by Auto Issues That Keep Coming Back?

Complete auto repair requires more than just tools and parts—it takes experience, careful diagnostics, and a commitment to doing the job right the first time. At Montiel's Mechanical Solutions, I bring over a decade of hands-on knowledge across all major systems. My shop in Livermore, CA is equipped to handle everything from routine maintenance to complex mechanical repairs for both residential and commercial vehicles. Whether you’re dealing with recurring engine problems or trying to prevent major breakdowns, I focus on solving issues accurately so you can get back on the road safely. What sets me apart is my one-on-one approach—every vehicle is inspected and serviced directly by me, ensuring personal accountability and consistent work quality. Since opening doors in 2024, I’ve built trust through certified service, insured protection, and straightforward communication that puts drivers at ease.

Areas of Specialization

I Specialize in the Following Services

Transmission Repair

A faulty transmission often shows up as delayed shifting, slipping gears, or strange noises while driving. These signs usually point to worn components or fluid leaks that need immediate attention to avoid total failure. With my transmission repair service, I inspect and address both mechanical and hydraulic issues using proven methods tailored to your make and model. I focus on accurate diagnostics before starting any repair work so that no unnecessary replacements are made. This helps extend your vehicle's life and avoids high future costs. Most importantly, you drive away with smoother gear changes and improved overall performance.

Trailer Repair

Towing trailers require dependable structural and electrical systems, especially if used regularly for business or travel. Damage to axles, brakes, or lighting creates safety risks on the road and increases wear on towing vehicles. My trailer repair service covers frame inspections, brake servicing, wiring fixes, and hitch alignment—all done with close attention to utility use and weight loads. I tailor repairs based on how your trailer operates day-to-day rather than applying generic fixes. The result is equipment that hauls better under pressure and meets highway safety standards without compromise.

Engine Diagnostic

When dashboard lights come on or performance drops suddenly, an accurate engine diagnostic becomes crucial to pinpointing root causes quickly. Ignoring early warning signs can lead to expensive repairs down the line or even full engine replacement. My engine diagnostic process uses advanced scanning tools combined with real-world troubleshooting techniques developed through years of fieldwork. Once the issue is identified, I walk you through recommended solutions clearly. You’ll leave understanding what’s happening under the hood—and with fewer surprises ahead.

Auto Brake Repair

Squealing sounds, soft pedal response, or longer stopping distances mean your braking system may be compromised. Driving with these symptoms increases accident risk and reduces confidence behind the wheel. My auto brake repair service starts with a detailed inspection of pads, rotors, calipers, and lines to uncover wear patterns or fluid concerns others might miss. I replace only what's necessary while restoring balance across all wheels for even stopping power. You regain safe control in traffic conditions—whether it’s city commuting or long-distance hauling.

How Do I Approach Each Job From Start to Finish?

I believe consistency in process leads to consistency in outcome—which is why every complete auto repair starts with listening closely to your concerns before touching a single part. I take pride in precision work guided by integrity rather than speed alone. As a one-person operation, you deal directly with me at every step—there are no intermediaries passing notes or overlooking key details. Communication stays open as repairs progress so there’s never confusion about status or cost changes mid-stream. Quality assurance matters most because I know every vehicle carries something valuable—your time, your work tools, your family’s safety.
