Diesel Repair Done Right in Medford, Oregon

Diesel engines are built to work hard, but they're not bulletproof. When your Power Stroke or Cummins starts losing power, blowing smoke, throwing codes, or just not running the way it should, you need a shop that knows these platforms. At HI Tech Transmission & Diesel Repair on Crater Lake Highway in Medford, diesel is what we do every day.

We work on Ford F-250, F-350, and Super Duty trucks with Power Stroke engines, and Dodge Ram 2500 and 3500 trucks with Cummins diesels, along with other heavy-duty vehicles 2005 and newer. Whether it's a fuel system issue, a failing injector, turbocharger trouble, an EGR problem, or a DEF system fault, we pull the codes, look at the live data, and find what's actually wrong before we give you a quote.

If your truck is your livelihood, you can't afford to have it sitting. We keep our schedule moving and our communication straight. You'll know what's wrong, what it costs to fix, and when you can pick it up. No runaround. All diesel repairs are covered by our 2-year/24,000-mile warranty, so you can put it back to work knowing the job was done right.

We also handle the maintenance side of diesel ownership: oil services, coolant flushes, fuel filter replacements, and the other things that keep a hard-working truck from turning into an expensive problem down the road. Bring your rig to us at 4025 Crater Lake Highway or call (541) 664-2991 to get scheduled.
