Transmission problems can be expensive to fix, so it is important to nip them in the bud as soon as possible. At Mechanic Northwest, our services are designed to do just that – keep your car’s transmission in good working order and prevent small problems from becoming big ones.

Since 2013, our ASE-certified mechanics have provided high-quality transmission services and expert auto repair throughout Federal Way and neighboring areas in King County.

Transmission Services We Offer

A healthy transmission is essential to the proper function of your vehicle, and we understand that you need your car to always be at its best. With our state-of-the-art facility and expert mechanics, we have the experience and expertise to meet all your automotive needs.

We offer the following services to help preserve the health of your vehicle:

  • Transmission Fluid Drain and Replacement

Transmission fluid is vital to keeping your transmission system running smoothly. Over time, transmission fluid breaks down and becomes less effective at lubricating your transmission. This can result in major damage and costly repairs.

At Mechanic Northwest, we can quickly and easily check your transmission fluid levels and top off your fluid if necessary. This simple maintenance procedure can save you a lot of money and hassle.

  • Transmission Filter Replacement

Transmission filters become clogged over time, and when they become too clogged, they can cause damage to your transmission. Our experienced mechanics will replace your transmission filter quickly and efficiently, ensuring that your transmission system is protected from harmful contaminants and deposits.

  • Transmission Flush

We offer a transmission flush service that will clean your system and allow for optimal smoothness and functionality. Old transmission fluid can lead to harmful deposits in your transmission system, so it’s important to keep it clean. Our flush service will remove all the old fluid and leave your transmission running like new.

  • Complete Transmission Service

This is the most comprehensive preventive transmission service we offer. Not only do we replace transmission fluid and filters, but we will also inspect various components for wear and tear. We also clean the transmission pan and replace the gasket material to prevent leaks.

While the pan is removed, we will also look for metal particles and friction damage. If we see any serious issues, we will let you know and recommend the best course of action.

I usually go to pep boys.. but the customer service there has gone down A LOT. They quoted me $1100 for what they thought needed to be done. And if I still liked pep boys I would’ve paid that but then I thought I better give my money to a shop I actually like. I went to mechanic northwest and they were soooo helpful and nice and I can tell they weren’t trying to take advantage of me or overcharge me. Which me being a young girl is usually what happens at mechanic shops. They were so transparent and kept me in the loop the entire time. The lady even took the time to explain everything and show me videos of what was done. If you’re tired of big corporate chain mechanic shops, give these guys a try. I love small family owned businesses. I ended up paying way less than what pep boys was going to charge me And my car runs great! Also I had just taken my car to pep boys a couple months ago and paid $1700 and they said I should have no more problems.. just to end up with my car having trouble again after 3 months. So yea it was time for a change. I highly recommend this shop!

I have only been in Washington for a few years and was looking for a small shop with quality work and fair prices. Called Mechanics Northwest and scheduled a diagnostic. They promptly assessed the issues and provided a quote. Repairs were completed earlier than promised and within the quoted cost. I am happy to have found a shop for all my future repair needs!!

This place deserves the highest of reviews. This is my second car I have taken to them right after purchasing them, without a doubt I get very well taken care of. The guys are very professional and Alnurfo is super knowledgeable and respectful. If your looking into getting your car fixed the right way the first time this is defined the place to go to.

From the moment I met the owner of Mechanic Northwest in the rear of the shop in the parking lot until I drove away fully satisfied that my 2008 Infinity FX35 had its brake job completed ✅ I was treated with respect and friendliness in the process of doing professional work. I definitely feel that I picked the right shop to do business! Thank you for such a pleasant experience. It was totally stress free. I fully trust these people to do work on all my vehicles in the future. And I highly recommend their service. Thankful for Mechanic Northwest!! They cared about my 🚘 !

Very nice people and very thorough. They made sure I knew what was wrong with my car and even went above and beyond to give my dealership an estimate of how much the repairs would cost.

I have an oil change every 4 to 6 months. I recently moved to Fed Way and needed to find a new place. I came across this shop and made an appt. My car seems to run better after having my oil changed here. Not sure what oil they used but I definitely feel a difference in my car. I'm taking it back for a recommended fluid flush. My car is an 07 so I'm sure it needs fresh fluid.

Brought my car in to get the power window fixed (came off the track) and an inspection, got it back same-day. Great service, communicative, friendly and courteous front desk staff. Will be going back if my car ever needs new repairs.

Again, Mechanic Northwest came through for our family when our older truck broke down. They were able to quickly diagnose the problem and call to discuss what can be don. They continue to be reasonably priced & have a fast turn around. I know I can count on them to take care of our vehicle needs.

Over heated on the side of the highway and got towed here. These guys got me in right away, diagnosed the problem, fixed it, and got me on the road in no time at a fair price. They were extremely friendly and transparent. I hung out in the garage with them while they worked on it. Definitely recommend their services.
