Transmission Repair inPortland & Vancouver
Transmission Repairs - Portland, OR
Transmission Work Done Honestly
Transmissions are where shops get dishonest fast. The script is: "sounds like it needs a rebuild, quote is four grand, can we start Monday?" — when half the time a fluid service, a solenoid replacement, or even a software update would have fixed it.
We diagnose before we repair. Period. Scan transmission-specific codes, inspect fluid condition, measure adaptation data, road-test under load, then tell you what's actually wrong and what it actually costs — before any work starts. If a fluid service fixes it, we tell you. If it really needs a rebuild, we tell you that too, with a written breakdown.
Automatic, manual, CVT, dual-clutch, and hybrid drivetrains.
Diagnose First, Repair Second
Transmissions fail in a lot of different ways, and the symptoms overlap. Slipping gears could be worn clutches; could also be low fluid, a stuck valve body solenoid, or a failed pressure sensor. Hard shifts could be internal mechanical damage; could also be degraded fluid or a software adaptation reset needed after a battery disconnect.
Shops that skip the diagnosis step default to the most expensive possibility — rebuild or replacement — because that's where the money is. We don't.
Our process is scan → inspect → test → recommend. You get a written diagnosis, the actual problem identified, and the real repair options (often including a "try the cheapest fix first" path). Honest work isn't always dramatic, but it saves customers thousands.

Transmission Services We Offer
Transmission Fluid Service
Scheduled fluid change (typically 30,000–60,000 miles), condition-based service, or preventive service after extended towing. We use manufacturer-spec fluid and perform a full fluid exchange — not just a drain-and-fill of 30% of the system.
Valve Body and Solenoid Service
Harsh shifts, delayed engagement, or specific gear problems often trace back to the valve body or a failed shift solenoid — often a repair in the $500–$1,500 range, not a full rebuild. We diagnose the specific failed component and replace it.
Transmission Rebuild
When the transmission truly needs internal work — worn clutches, failed bands, damaged gears — we rebuild with quality components and a NAPA-backed warranty. You'll see the teardown findings and approve the scope before reassembly.
Transmission Replacement
Sometimes replacement is cheaper and faster than rebuild — especially with remanufactured units for common vehicles. We'll walk you through the options, cost difference, and warranty coverage for each path.
Hybrid and CVT Service
Continuously variable transmissions (CVTs) require manufacturer-specific fluid and procedure; hybrid transaxles often combine traditional gearsets with high-voltage motor-generators. We're certified for both and handle them to spec.
