Engine & Transmission Performance You Can Count On

Your engine and transmission are the core of your vehicle’s performance. When they’re not operating the way they should, you feel it immediately-loss of power, rough shifts, strange noises, or warning lights that won’t stay off. At Tom Dwyer Automotive Services, we combine deep experience with precise diagnostic tools to find the root cause quickly and fix the issues that truly matter. Our approach protects your vehicle, your budget, and your long-term reliability.

Engine Services

We diagnose and repair the core systems that affect power, performance, and drivability - including misfires, timing components, fuel delivery issues, ignition problems, and engine mounts. Our testing tools help us pinpoint the cause quickly and accurately.

Transmission Services

From harsh shifts to slipping, delayed engagement, or clutch concerns, we identify what’s happening inside your automatic or manual transmission. We handle fluid leaks, driveline vibrations, shift faults, and related mechanical problems with a methodical, data-driven approach.

Maintenance

Routine services like timing belt replacement, fluid exchanges, and early repair of minor leaks help you avoid costly engine or transmission failures. Our inspections also spot developing issues before they lead to major repairs, saving you time, money, and stress on the road.

Engine Services

When something isn’t right – reduced performance, strange noises, leaks, or warning lights – you need accurate testing and careful evaluation to prevent small issues from turning into major repairs. Our ASE-Certified Technicians use manufacturer-level tools, hands-on inspection, and real-world road testing to pinpoint engine concerns quickly and correctly. From oil leaks to misfires, we focus on the true root cause so you only pay for the repairs your vehicle actually needs.

Transmission Services

Your transmission is responsible for delivering smooth, controlled power to the wheels – whether you drive an automatic, CVT, or manual. When shifting feels harsh, delayed, or unpredictable, it’s a sign that something inside isn’t operating the way it should. Accurate diagnosis is essential, because ignoring early symptoms can lead to costly internal damage.

At Tom Dwyer Automotive Services, we use detailed testing, fluid analysis, and on-road evaluation to understand how your transmission is behaving and why. Our Technicians focus on identifying the true cause of the issue, helping you make informed decisions and avoid unnecessary repairs.

The Tom Dwyer Way

We don’t guess with transmission problems. Every evaluation includes clear communication about what we found, what’s causing the symptoms, and what’s needed to protect the longevity of your vehicle. You’ll receive honest repair options and transparent guidance every step of the way.
