Mount Vernon, Oak Harbor & Sedro-Woolley Auto Repair

I had the gentlemen here recently replace the transmission in my 1988 GMC Suburban, as well as a few other things. Not only were they timely with the repairs, but they kept me up to date with what was going on and how much it would cost. I recommend them to anyone I know for anything from oil changes to heavy duty rework.

The crew at the Oak Harbor location is great! They are knowledgeable, and explain everything that they are doing and what needs to be done. I wouldn't go anywhere else and I live almost 3 hours away!

Gateway Oak Harbor cares about you and your car. Dave often takes the time to tell me how things happen, and how not to have things happen. If you want to feel safe the whole time you're driving, take your vehicle to Gateway Oak Harbor.

Dave, Charles, and the team at Gateway Oak Harbor are the best I've found in 20 years of looking for reliable mechanics. They make me feel like a pilot whose got the best ground crew around. The new office is very nice, and the parking is easy.

I’m new to the area and did a lot of research before taking my car in to get it checked out. Dave was extremely knowledgeable and helpful! You can tell he really cares about his customers. He did free diagnostics to find the problem and called with an estimate prior to proceeding. I will recommend this shop to anyone needing work done on their car!

My car drives wonderfully after having an expert tune up at Gateway Transmissions.

Great work, car runs like new.

Gateway is my go to place for anything my car needs. Dave and the team are awesome to work with and the job is always completed in a timely fashion. I feel very confident recommending them.
