Chevy & GMC Repair in Hood River, Oregon

Trusted Chevy & GMC Mechanic in Hood River

GM trucks earn their keep around the Gorge — hauling, towing, and clocking serious miles between Hood River, Portland, and points east. When your Silverado, Sierra, Tahoe, or Suburban needs work, Ortigoza Auto Repair has you covered. We know the LS engines, the Duramax diesels, the 6L80/8L90/10L80 transmissions, and the patterns that show up on these trucks at 100k, 150k, and 200k miles.

Common Chevy & GMC Repairs

AFM / DOD Lifter Failure

The 5.3L and 6.2L V8s with Active Fuel Management (cylinder deactivation) have a well-documented lifter failure problem. We diagnose, replace failed lifters, and can perform AFM deletes for owners who want a permanent fix.

Duramax Diesel Service

LB7, LLY, LBZ, LMM, LML, L5P — we service them all. Injector replacement, CP4 issues on later trucks, turbo work, EGR cooler service, and Allison transmission care. See our diesel repair page for more.

Transfer Case & 4WD Service

NP246, MP3023, MP3024 transfer cases, encoder motor failures, and full 4WD system diagnosis. Critical for trucks that actually see snow and mud.

Transmission Service

4L60, 4L80, 6L80, 6L90, 8L90, 10L80, Allison 1000 — fluid service, valve body, solenoid pack, and rebuilds.

Steering & Suspension

Pitman arms, idler arms, tie rods, ball joints, hub bearings, and lift kits. Aggressive use catches up to these trucks — we handle it.

Cooling System

Water pumps, radiators, fan clutches, intercooler boots on Duramax. Important especially if you tow over Mt. Hood or up to Cooper Spur.

GM Maintenance Schedule

Modern GM trucks need disciplined maintenance to make it past 200,000 miles. We can build you a plan: oil and filter (with the right dexos spec), transfer case fluid, differential fluid (front and rear), transmission service, coolant, brake fluid, and spark plugs. The "extended life" intervals leave a lot to be desired — we'll tell you what to actually do.

• Real diagnoses, not just code-clearing.
• Fair pricing — significantly less than the dealer.
• Fast turnaround, often same day.
• Diesel experience for Duramax owners.
• Honest about what your truck needs vs. doesn't.
