Transmission Repair
Your vehicle’s transmission is responsible for delivering power from the engine to the wheels. Over time, wear and tear can cause transmission issues, leading to rough shifting, slipping gears, or unusual noises. At Stonum Automotive, we provide professional auto transmission repair services, including:
✔ Transmission fluid checks and flushes to maintain smooth gear shifts.
✔ Clutch repair and replacement for manual transmissions.
✔ Full transmission diagnostics to detect early signs of failure.
If you notice slipping gears, delayed acceleration, or a blinking check engine light, bring your car in for an inspection. Ignoring transmission issues can lead to costly repairs or total failure—don’t wait until it’s too late!
Engine Maintenance
Regular engine maintenance extends your car’s lifespan and improves fuel efficiency. Our expert technicians perform thorough engine inspections, addressing common problems before they become major repairs. Our engine maintenance services include:
✔ Oil changes and fluid top-offs to prevent overheating and sludge buildup.
✔ Spark plug replacements for smooth ignition and fuel efficiency.
✔ Check engine light diagnostics to pinpoint underlying issues.
If your flashing check engine light turns on, it’s a sign that immediate attention is needed. Ignoring it could lead to severe engine damage—let us diagnose the issue and keep your car running safely.

Engine Maintenance & Replacement
Sometimes, an engine reaches the end of its lifespan. If repairs are no longer cost-effective, we provide engine replacement services to get your car back on the road. Our team will assess your engine’s condition and recommend the best course of action.
✔ Full engine diagnostics to determine repair vs. replacement.
✔ Engine rebuilds for cost-effective restoration.
✔ Quality replacement engines for long-term reliability.
If your engine is knocking, stalling, or has excessive oil consumption, it may be time for a replacement. Trust Stonum Automotive, one of the most reliable Longmont auto repair shops, for expert service.
Timing Belt Replacement
Your timing belt ensures your engine’s valves and pistons move in sync. If it snaps or wears out, it can cause catastrophic engine damage. To avoid expensive repairs, we recommend regular timing belt inspections and replacements.
✔ Manufacturer-recommended timing belt replacements based on mileage.
✔ Timing belt tension adjustments to ensure smooth operation.
✔ Water pump replacement (if needed) to prevent overheating.
If your check engine light turns on and you hear ticking noises from the engine, don’t ignore it—schedule a timing belt inspection today.
Cylinder Repair & Replacement
The cylinders in your engine house the pistons and play a crucial role in combustion. If a cylinder is cracked or has compression issues, it can lead to loss of power, poor fuel efficiency, and engine misfires.
✔ Cylinder block inspections to check for cracks or leaks.
✔ Cylinder head reconditioning to restore airflow and compression.
✔ Valve and gasket replacements to maintain proper sealing.
A blinking check engine light may indicate cylinder misfires—if you notice reduced performance, rough idling, or overheating, visit our Longmont auto repair shop for expert cylinder repair services.
