I wasted an Asian transmission in a Ram 3500 with 34,000 miles on it. Pro tip, remove the transmission cooler thermostat. Gene and his guys pulled that transmission, rebuilt it with new and improved parts, and gave it back to me. The truck shifts much better than it did and runs cooler than it did when it was new. This shop is not cheap, nor overly expensive, their quality of work is worth every penny spent. Thanks Gene read more

I mistakingly put gasoline in my diesel truck. I had the truck towed to Gene's Sound Diesel Performance on Saturday at about 5pm. Gene got my truck drained, cleaned and working perfectly for pickup the next day Sunday at 10:30am. Where else are you going to get such fast service? I just drove the truck 130 miles home on the freeway. The truck runs as smooth as ever and just as much power as ever. I recommend Sound Diesel Performance. read more

Gene and his crew are always so helpful and efficient. Prices are reasonable. This is a great business.

Thanks Gene, your a stand-up guy, straight shooter. You and your crew did a excellent job fixing my truck. I appreciate your honesty and your price. Thanks again read more

I'm a repeat customer who drives from Olympia to Auburn regardless of traffic when diesel repairs/maintenance are needed. I recently called Sound Diesel for a 2007 GMC Duramax with a fuel leak and power steering leak. Gene the owner got us right in and the next day he had it quickly diagnosed and fixed the same day. Gene is a wealth of knowledge and true professional you can be confident with. He takes pride in his work and gets the job done right the first time! Thanks Gene and crew!!! read more

My husband and I cannot say enough about Gene and his crew. We would give them 10 Stars if we could. It started from our very first encounter. We have a 1997 Ford F350 crew cab that we have had for 20+ years. We needed to get it ready for an upcoming camp trip with the grandkids. It needed a tremendous amount of work, but from day 1, we were given honest and straightforward information regarding what to expect as far as cost, parts and timeline. Gene assured us it would be done on time if not before. Boy did he deliver on his promise!!!! I thought customer service was a thing of the past but Gene lives and breathes it every day. Our truck runs like it is brand new and ready to go another 200,000 miles. Happy customers Craig & Cindy K read more

Repairs completed resulted in needing to be fixed by another shop, not once - but twice - within 3 - 6 months of Gene's shop fixing my truck. He offered a warranty originally over the phone and when asked for the shop to honor the verbal agreement in person he claimed he didn't offer it to begin with. LIterally driving down the road and parts fell off. He used subpar materials to begin with and the work is shoddy. I don't recommend using this location for repairs. Lies and headaches. Run away while you can. read more

I have an '01 Dodge Ram 2500 affectionately referred to as "The Hildabeast". I am one of those people who love driving, and my vehicles bring me an immense amount of happiness. This truck had been the perfect rig for a long time! But unfortunately, I was to become victim of the dreaded Curse of the "53" block. At around 238,000 miles, she finally gave out. I was overheating, and finally found the coolant leak. Sure enough, it was a cracked block. As I mentioned, I love my vehicles. I typically do my own work, but I didn't have the time, tooling, space, nor frankly the inclination for a project this big. I was pretty worried about where I would go to have the work done. I definitely wanted to keep the truck. It's my ultimate rig, with a 6 speed manual. It's my "retirement" truck. I spent the better part of a Saturday going over reviews of various places, and kept coming back to Sound Diesel. Reviews mean a lot to me, and Gene had some great ones, so I decided to take it to him. Gene immediately diagnosed the cracked block and was straight with me from the get go. "I don't do anything stock" he said and he gave me a quote. It was a good quote for the high quality work that I expected and I gave him the go ahead. I could tell from the start that Gene and I share the same philosophy....do the job once and do it right! Gene was amazing throughout the entire build process! He was very communicative, giving me constant updates as the work was being done, from tear down to buildup. He invited me down to the shop to inspect the block once it was out and torn down, and again several more times as the project continued. I was very impressed with the work, and the atmosphere of the shop. The mechanics he has working for him are also consummate professionals and I enjoyed chatting with them. Finally came the big day when Gene sent me a video of the truck being fired up for the first time, and man it lit right off! He then brought me down to the shop to take it for a drive. Holy sweet mother of whiplash! I knew that my truck was going to turn out good, but I had absolutely NO IDEA of the level of good!!!! This thing is a whole new animal!! Gene made some upgrades for me along the way and I am so glad I listened to his advice. The new clutch he put in is like butter, and the new tuner is much better and more user friendly! Best of all with the new, upgraded turbo, injectors, and Gene's master tuning, the power output is INCREDIBLE!!!!! I actually have to be more careful now because she will break loose without so much as thinking about it if I am not! Hilda is a whole new beast, and I would put her up against any new truck in her class! Thank you Gene, and thanks to your employees as well for the First Class treatment and the love and care you showed my truck!! You have a customer for life! I encourage anyone needing work done on their diesel to go straight Sound Diesel! You will not be disappointed!! read more

Sound Diesel, it doesn't look like much. But Gene the owner and mechanic. With his team of mechanics, know their stuff. I had a blown transmission, and he explained to me what the cause was and the problem. Did it in away that a non mechanic, could understand. His turn around time to get the job done was on point, if not faster. The bonus is that he saved me a couple of hundred dollars, if not a thousand or 2, to get my transmission fixed. That the dealer wouldn't touch. Thanks again Gene Another value customer read more

Purchased a new vehicle and thought it had problems. Made an appointment to have it looked at and was explained what i thought were issues were normal, and he explained what they were clearly. Took extra time giving me some pointers on fuel additive to help clean the injectors and caught my air cleaner being plugged. Total cost of inspection and advice was a handshake and a thank you. Earned a future customer for sure, Gene is a stand up guy when those are hard to find anymore. Highly recommend. read more

Gene is AWESOME! He knows his stuff, ZERO doubt. He is a great human. He will work with you 100%. If I have an issue I can fix, I'm packing it up and driving 3 hours to him. That's what's up. I don't do many reviews but have to here cuz he is the best I have seen in WA. 2012 Chevy 6.6 Turbo DRW & any future trucks will come here to read more

Tragically we blew the engine in our diesel truck on the freeway. A quick check of local diesel shops showed Sound Diesel had good reviews. So that's where it was towed. Just a shot in the dark that this was a good shop. Gene is like "Rain Man" for diesel engines!!! He pulled out all the stops. Found is a new engine plus a whole bunch of other stuff. My understanding of internal combustion engines is pretty basic.... ie vroom vroom is good. BLAT blat not so good.. and knock knock blam is very very bad. He sent video clips, called with updates, explained in detail things I immediately forgot. But I totally appreciated the extra effort and careful explanations. My truck is back more powerful than it ever was before with a nice vroom vroom purrr read more

This is a great shop! I'm out in CA and was going to buy a diesel and have it shipped to CA but had the guys at sound check it out first. They did a great job and you can tell these guys are honest and experts. They definitely earned a customer for life! read more

When you love what you do, you'll never "work" another day in your life. Gene epitomizes this motto! The guy knows Diesel engines and loves making them run right. Fast service, incredible attention to detail, fair prices and a really knowledgeable pro. Rick and I highly recommend this shop. We won't go to the dealer again! read more

A week before Christmas my truck broke down and I called Gene for some advice. After speaking with him I knew that i wanted him and his team to work on my diesel. I am a diesel mechanic for a construction equipment dealer and i KNOW that gene knows what he is talking about and has extensive knowledge with diesel truck. In all it was a 4 day turn around for a very big job. Gene and his team will take care of you. He is a honest man who shares his knowledge with his customers and his team. I am new to the state and this is where I will be taking my 3 Powerstrokes when they get sick. read more

On my way to work nights and fuel was pouring out of my engine bay. After a 14 hour shift I get towed to Sound Diesel and Gene drops everything he's doing to diagnose and fix. I was prepared to get a huge bill and wait a few days. Gene got me out the door in under an hour. If you're bringing your diesel anywhere else you're doing yourself a disservice! Gene calls me up later in the day just to make sure the truck made the ride back home ok! read more

Had my Silverado towed in and they had the issue diagnosed in 10 minutes. Gene very thoroughly explained what needed to be done, and also walked me through some options to make my truck more reliable. I authorized the work, and they got it done earlier than promised. Repair and upgrade work was fairly priced, and there were no surprises. Gene is a great communicator (RARE in a mechanic) and also a great mechanic. I've never seen a crew more focused on doing the repair right and customer satisfaction. I am thrilled to have found a shop for my diesel pick up. read more

Called Gene and he was able to get me in for a diagnosis the next day. He even ended up fixing my radiator on the spot, taking time after closing to get it done right. And I could not beat the pricing! Gene even called me after I left to make sure everything was still good with the truck. I will definitely be bringing my truck back here for any other repairs. I highly recommend them! read more

Had my 97 7.3 acting up and gave up after a couple attempts at fixing it myself and didn't want to take it to a shop after my last horrible experience with plateau diesel in enumclaw and I stumbled across sound diesel performance on yelp and saw the reviews and got ahold of gene (the owner) and this guy is the real deal. Got my truck into him and thought it could be a week or so before I got the news and he called me the next day with it being ready and running. Unbelievably happy and recommend read more

Took my 02 f350 7.3 for upgrade to the up pipes to the turbo and exhaust break work. Gene gave me outstanding recommendation & A real good price. Would recommend to anyone. read more

Gene was called in to the dealership that I bought my truck from and was able to take my truck and fix all of my problems within a couple days! Much appreciated! read more

I never actually made it to sound diesel. But, the head guy gave me some excellent advice for dealing with my situation. I would trust him with my vehicle for future service. read more

I've only taken my truck to Gene, he's the man. Even when I've been stranded in the side of the road hours away he's come and rescued me. Always answers my calls and takes care of me. I've been to other diesel shops and no one knows the the trucks like he does, he's a mastermind when it comes to fixing these trucks. He always take care of me and always gives me the best coats he can. Always affordable and backs his work. I wouldn't take my truck to anyone else read more

Sound Diesel Performance - Auto Repair Near Me - Auburn, Washington

My wife and I were in the Seattle area visiting our Grandchildren over Labor Day/21. We had driven from WV in our 2005 F350 CC FX4 truck camper powered by a 6.0L powerstroke diesel. On our drive out to Seattle we started to experience "hot start" problems with our truck. We called or stopped at a majority of the Ford Dealers in a 100 mile radius of Seattle and to say they were less than helpful would be an understatement. We were told it would be a minimum of 3 to 4 weeks before a mechanic could even look at the truck to diagnose the problem. Luckily my wife found Sound Performance Diesel on the net. We stopped by the shop unannounced and met with the owner Gene. Gene told us if we could bring the truck by in 3 days and leave it, he would try to diagnose the problem and provide an estimate. (We were driving a rental car). Gene was able to pinpoint the problem, gave us an estimate as to time and cost. Well, while Gene was fixing the problem he found several serious issues including a bad fuel injector, plugging oil inner-cooler, turbo charger exhaust manifolds and turbo actuator mechanism. Even though Gene was down a crew member, he and his team were able repair the additional engine issues in only a few days (half the time I was expecting) and at a very reasonable cost given parts were almost $2,500. It should be noted that I had the truck mechanically inspected and new fuel injectors and glow plugs installed only 8 months and 11,000 miles prior to Gene working on the truck. Sound Performance Diesel went beyond the call of duty to help us out and get us on our way. I had shared with Gene we would be leaving to drive back to our home in 2 days (6 days and 2,800 mile drive). On our 3rd day on the road Gene called me to check on how the truck was driving. I told him "like a dream". If you have a diesel truck and are located in western WA or find yourself in the area, I would highly recommend making the effort to take your diesel truck to Gene and his team at Sound Performance Diesel for repairs or a serious "checkup". One "Very Satisfied" customer. read more

So I'm an idiot and decided to read the internet when my duramax went into limp mode, I did the injector wire replacement on 2 and 7 but no fix. I had all kinds of issues going on and the dealership wanted a ton of money to even look at it. I went to sound diesel and talked to Gene and told him what was up with it. After some talk and dropping it off I found out the injections were bad and the water pump, glow plug and the injectors took out the ECM since I kept driving it. And gene never asked me to just believe him but always had proof from chevy to back his diagnosis; not only did he do that but he saved me a huge amount on money that the job should have costed. All in all I not only did I find an awesome shop to work on my truck but the owner and techs there are all friend now. Please don't hesitate to bring your diesel here. read more

took my 2000 dodge to gene for repair. turned out my engine was bad he built a newer engine for my truck. it turned out great. service was excellent truck runs real well would recommend him verses the other shop that had worked on my truck read more

I posted a detailed review of Sound Diesel and Yelp did not recommend it. Go to the bottom of the review page and click on the additional reviews. Short version of my review...I highly recommend Sound Diesel. read more

I have been doing business with Gene for a short time now but for me he and his team have done an outstanding job. He has gotten my problems fixed quickly and professionally and has not over charged me even when it was and emergency. I have already recommended several of my friends and will continue to do so. And until some time in the future when I am no longer able to drive he will have my 2007.5 Ram 3500 as his patient. read more

In a nut shell this dude is a NUT!!! I see some positive reviews but idk he must have paid for them.. I never asked this guy for a hand out or a screaming deal that he would supposedly " loose his ass on" I just wanted somethings done mainly a pre-sale inspection which was going to cost $300- $350 and I was fine with paying because he said that money would be forwarded to any repairs done in the shop... ok cool!! Inspection per "nut" was GREAT TRUCK no problems and by the way no charge for the inspection ... uh k weird... then deterred me from getting a fuel system installed quoted at $900 installed, instead lead me to just a different filter set up.. ok all good , now for the real reason he was saving me money.. he had a set of wheels and tires for sale that would fit my truck at a SCREAMIN DEAL!!!! ( turns out I looked at the other sets before I bought his all the same price used ) but I did prefer his set which he said came with a matching spare ( I have a witness ) so I got the wheels and tires, alignment filter, and level kit after all said and done looking over my truck found 2 holes in the roof, a leaking brake booster, kinked supply and return lines bad backup sensors and I may have a bad injector ( all would have been nice to know before I bought the truck)... I called to inquire about the missing matching spare which now became a tire that he just had somewhere and had to find it but it had no wheel.. then I simply asked about a part installed and where it was located because I just didn't see it OMG don't ask these questions because your attacking him like a pit bull off a leash and calling him a LIAR!!! I got him to say they were at the bottom of the shock ( extention ) nope don't see them ( now they are at the top of the shock.. ) oh ok way up there I looked and found them cool.... never once did I call him a liar or try to insinuate he was lying and I tried to explain that to him trying to keep as calm as possible but now I was arguing with him funny thing is he did the same thing to my buddy when he asked a question regarding his truck...he loves hearing himself talk and strokes the hell out of his little ego and he obviously don't need new business because he thinks he can treat customers like that we'll I hope more people that may have experienced this yelp about it after reading this good luck Ralphy.. read more
