Engine Diagnostics and Repair in Medford, Oregon

A check engine light doesn't tell you much on its own. It tells you something triggered a fault code, but codes don't fix engines -- a technician who knows how to read the full picture does. At HI Tech Transmission & Diesel Repair on Crater Lake Highway in Medford, we run a complete diagnostic process that looks at live data, fuel trims, compression, oil condition, and cooling system performance. That gives us an actual diagnosis, not a parts-swapping guessing game.

We work on diesel trucks and American-made vehicles from 2005 forward, including Ford Power Stroke and Dodge Cummins platforms. If your truck is running rough, losing power, burning oil, blowing smoke, or overheating, those symptoms point somewhere specific. Our job is to find where and tell you straight what it's going to take to fix it.

Engine problems don't get cheaper when you wait. A minor issue like a failing injector or a coolant leak can turn into head gasket damage or cylinder scoring if it runs long enough. We see it happen more than we'd like. When you bring your truck in, we'll give you an honest assessment of where things stand and a fair price on the repair -- before we start, not after.

Whether you're dealing with something minor like a sensor replacement or intake repair, or something more serious like internal engine work, we handle it the same way: correct diagnosis first, then a clear quote, then quality work backed by our 2-year/24,000-mile warranty. Call us at (541) 664-2991 or book online to get your truck in.
