Ace Transmission in
Knoxville (TN)

Extremely positive experience. Our 2016 Chevy Traverse's transmission was slipping. On the recommendation from a family member we contacted Ace Transmission. Michael, the owner was very helpful. He arranged a tow truck which arrived very quickly. He gave us a diagnosis and an estimate within a few days. The estimate was , I felt, reasonable and fair He also worked with us on the payment. Within a few days we had our car back. I waited about 6 weeks to submit this review as I wanted to see how are the car performed. No problems at all and I'm confident in the work that was performed. I feel I've found a trusted mechanic.

I needed a new transmission for my 2017 Nissan. I must say that I am behind impressed with Ace Transmission! Not only was Mike friendly, professional, and great to work with, he also provided the best price out of all the other transmission shops in Knoxville. They provided a free tow to their shop on a Monday evening and the repairs were completed on Thursday! I highly recommend that if you need transmission work, stop in or give them a call for a free diagnoses and repairs!!!

After a really bad experience with the new owners at Chip's Transmission in Sevierville, it was great to walk into Ace and be greeted by Michael. He was totally up front about all repairs, even sent pictures of broken bad parts and was first class to deal with!! Can't say enough about the fast, honest, work and customer service was out the roof!! Thanks again to Michael and the gang!!

We brought our car to Michael and was very courteous and professional. He treated us more than fairly and we would go to his shop again if needed. Thank you Michael!

⭐️⭐️⭐️⭐️⭐️ Michael did a fantastic job! I contacted multiple shops—some refused to service my 2018 Ford and others never returned my calls, even after I left voicemails. Michael, on the other hand, was polite, professional, and extremely helpful. He even removed the charge for the TCM replacement since it was related to a larger transmission issue that caused my repair to take another week. He answered all of my questions, kept me updated throughout the process, and went above and beyond to make sure I was taken care of. Please don’t hesitate to reach out to this shop—they are amazing, honest people! I’m originally from Knoxville but live out of town, and I was stuck in a bind trying to find someone trustworthy to fix my car. I’m so grateful I found the right place. Thank you, thank you! 🙌

I can't say enough good things about Ace Transmission. I brought my van in with the notorious 6L80E transmission issue, which is something I was really dreading. From the moment I walked in, the service was fantastic. The team was incredibly knowledgeable and transparent, explaining everything they needed to do. I was very impressed with how fair the final price was, especially considering the complexity of the repair. Even better, they had my van completed and back to me in an unbelievably fast turnaround time. They truly went above and beyond to make sure I was completely taken care of. It's rare to find this level of honesty and professionalism in a repair shop. I highly recommend Ace Transmission to anyone in need of their services. Thanks again!

To everyone looking at reviews to have transmission, brakes Or general automotive mechanical work done this Ace transmission shop on Clinton highway is the place! From general manager Michael, which is simply the best to work with and will really try to give you the best honest advice possible. My technician Lee was very knowledgeable and gave me a couple of brake tips as well. He is also a friendly person. Tony and Chris were very nice and helpful too, this is one awesome staff and will treat you right! This will be my new shop for my vehicles, their prices are very fair as well. Great job guys!!

⭐⭐⭐⭐⭐ I can’t thank Michael at Ace Transmission enough for the incredible service! My transmission blew out while traveling from Ohio to Georgia, leaving me stranded in Tennessee. Michael and his team stepped up big time, offering me a fantastic deal on a full rebuild and prioritizing my repair since I was out of town. They were professional, fast, and went above and beyond by letting us hang out in their comfortable lobby while we sorted out our travel plans. Michael’s kindness and expertise turned a stressful situation into a smooth experience. Highly recommend Ace Transmission to anyone in need of top-notch service!

I don't normally write reviews. When I do, it takes something special! I can't recommend Ace Transmission enough! Our family was on vacation in the Gatlinburg/Pigeon Forge area from Fort Worth, Texas. We were supposed to drive back home at the end of the week on Friday. Two days before that, Wednesday evening, the transmission on our 2014 GMC Sierra decides to go out at 150k miles. By that time in the day, transmission shops were already closed for the day. Thursday morning, I started calling around to all the local transmission shops in the area and they're telling us we're looking at anywhere from 1 to 3 weeks to get our truck in the shop and fixed and that we're lucky we got 150k miles out of the original transmission. They typically don't last that long. We didn't know. All of a sudden, we're having to figure out if we extend our stay and make other living accommodations and arrangements with work, or if we rent a car and drive home, then fly back from Texas to pick up our truck once it's fixed. I decided to expand my search for a transmission shop up to Knoxville. After a few phone calls, I was fortunate to stumble across Michael, the General Manager at Ace Transmission. I quickly understood why they have so many great reviews. Right off the bat, I could tell he knew his transmissions and what he was talking about, which instilled a lot of trust and confidence. He was very personable and his customer service was second to none. He said he could get our truck in that day to do a diagnostics on it, with the goal of having it fixed by the following Monday, which would have only set our return to work back by a couple of days that next week. So we decided to have it towed up to Knoxville that morning. The tow truck driver was very familiar with Ace Transmission and couldn't say enough good things about them, that it was a family run business and that they are honest and say it how it is and are great at what they do. He said we were in good hands. Once our truck arrived to Ace Transmission, their crew was right on it and Michael gave us a call back that afternoon with the assessment, confirming that we needed a full transmission rebuild. He said we were realistically looking at Monday before our truck would be fixed, since they are closed on the weekends, but that there was a slight chance he could get it done by the end of the next day, on Friday. So we set our expectations for Monday, but were hoping for it to be done that next day on Friday. Michael kept us aprised and sent texts with photos of the work his crew were doing. Friday late morning he called and said they were able to make good progress and that there was a good chance they'd be able to get it done by the end of the day, but that he would keep us posted. Michael made our trip when he called us later that afternoon and said "Come pick it up! It's done!". We couldn't believe that they were able to get it done in a day! We got to the shop and Michael said he took it out for a test drive and it's driving like new. As part of the rebuild they also add some upgrades and performance parts to avoid/resolve any known issues with the existing GMC transmissions. His prices were fair and right in-line with, or less than, other quotes we had received for a full transmission rebuild. We drove it home to Fort Worth, Texas that weekend and had zero issues with it. It really did drive like a new truck! We have since been home for about 2 weeks and have probably put about 1500 miles on the new transmission. It drives like a dream and I would even dare to say it has gotten better the more it is driven. We can't thank Michael and his crew enough for saving our vacation and making it possible for us to get back home in time for work and other obligations on Monday morning! Also, saved us a ton of money in the long run for not having to extend our stay or make other arrangements to get our truck back home. Know that you can trust Ace Transmission with all of your transmission needs and that no one will take better care of you and your vehicle! Thank you!!!

The crew at Ace transmission were great to work with. Very up front and honest about my car. I didn’t feel like they were taking advantage of me whatsoever, which is usually the feeling one can get taking your car for service. This is a locally owned small business and they deserve all the business for the experience they provided. I talked to a few of the guys that worked there and you can hear their passion for cars. They beat the price quotes I got from 4 other shops. But more importantly they communicated everything that was going on before doing further work.

I had a great experience on my first visit to this family owned and operated mechanic shop. I called for a quote for a transmission oil flush and their prices were better than the other 4 shops I called. They cautioned to do a simple drain and fill first to make sure I didn’t have any transmission issues first before doing a full service to potentially cause any harm. Michael ( shop manager ) texted me pictures every step of the way confirming everything looked good to go ahead and fully service my tranny oil. No up sell, no hidden fees no BS!! I don’t think I’ve ever been able to say this about a mechanic shop before. They have my future business for sure. Great job Ace crew!!

A great shop and Michael and his staff (call-out here to Angel) are exemplary! I took my wife’s Ford Escape there after they did such a great job on my Toyota Corrolla ladt year. They did an excellent job and Angel sent me pictures to update their progress. They even finished sooner than expected! I recommend Ace Transmission to anyone looking to try and frugally extend your car’s life a few years rather than drop a lot of dollars on a new or slightly used vehicle.

Guys took care of our 2016 Chevrolet Suburban 3 weeks ago and it’s riding smooth as silk. We called several places around town all of which were weeks to months out, Ace was able to get us a free diagnostic as soon as we could get it to them and within a week we had a rebuilt transmission. Very down to earth family owned business. Hopefully I don't have to but I would use them again, no hesitation.

Awsome folks Michael was great communicated everything gave the best estimate kept the price at the estimate work was done ahead of schedule. Overall, excellent experience thank you Ace Transmission .

Automotive repair can be split into three categories. The mechanics, the transmission, and auto body. That said Ace is my transmission shop from now on. They came highly recommended by the reputable people I already depend on, and Ace did not disappoint, so I highly recommend. Just fantastic guys. The manager, Michael; I believe is his name, is just about as good as it gets. Fair price, honest people doing honest work, and their followup is unparalleled. Call, and if Michael doesn't answer, leave a message, and he will get back to you either that day or first thing the next day. I had Ace do a full transmission swap for my daily driver, and they were able to complete the job in less than 24 hrs. The work is top notch, and I went back one week later, and they were happy to check fluid and test drive the car to assure both me, and himself the transmission is operating properly. It's been 3 weeks since the work was completed, and I am completely satisfied with the transmission, the quality of work, and the personalized followup service, and the most beautiful aloe plants. If I was any happier I'd have to sit on my hands to keep from clapping.. 😂 I Highly recommend Ace Transmission for all your transmission needs.

My car had never gotten a transmission service and it was severely overdue. Michael at Ace had a great recommendation for what to do with my car, didn’t haggle me into any extra services, explained everything to me in detail, and had my car serviced in a short time! It was a great experience, highly recommend

I highly recommend Ace Transmission. Nobody wants to hear that you need a Transmission repair but Ace was great to work with. They really did there best to be reasonable with the price and work with you. They also took the time to really diagnosis my van before jumping to yeah you need a new Transmission like other places would have done. Thank you to Michael, and all the Ace workers for a great experience.

Needed a new transmission, unfortunately that is never cheap but Ace Transmission was the lowest quote I found in the area. They did a great job and had it done quickly. They stand by their work. Hopefully I will never need their services again but if so I would absolutely use them!

Michael the manager was so knowledgeable and very helpful with all my problems.. he was very patient with all of my questions and even sent me pictures of my car in the process of it being fixed!! I got my car in 1 day after calling and was fixed the very next week and is as good as new! Will definitely be back!

Had my transmission replaced here in my 2015 Yukon. It might have been the best experience I’ve ever had with a shop. Michael went above and beyond to get me the help I needed. They did a great job and my 2015 Yukon drives like a brand new vehicle. Thanks for all the help and if we need any transmission work in the future it’s definitely coming to you all!!

My daughter's (Lady Vol rower) car broke down on the way to the lake in KY on Labor Day weekend. Her transmission went out and they helped me get a reasonable tow back to Knoxville, which was 1.5 hours away. I was quoted $550 from a towing company but Ace suggested Sutherland which did it for $300. I called another recommended mechanic shop and they said it would be 2 weeks before they could look at the car. Ace had the vehicle fixed with a new transmission in less than a week. They even met me at the shop on Saturday to pick up the car since we were going to be in town for a Tennessee Football game. I can't recommend this place enough. Thanks so much!

Michael and his staff were great! I also enjoyed speaking with Andy very much. Took my 2007 Toyota Corolla in for a new transmission and after a recommendation from my local repair shop said their underwriter would only go to them for transmission work. They did a great job and my manual transmission is better than new. I had a minor issue with my floor mat interfering with the clutch, but they deduced that issue immediately and the problem when away with a smaller mat. I highly recommend Ace and will take my 2006 Ford Escape to them next year.

Michael was so nice. They offered to test my car's transmission at no charge. They were quick to give me an evaluation and recommendation. Very polite, honest and made me feel confident in the repairs needed. I highly recommend this company and I will be referring all my friends and family.

Went into Ace transmission a couple weeks ago because I was having transmission problems, as I suspected I needed a new transmission. Michael, the manager there was very kind, easy to work with and generally a great guy. There were a few complications with The install, but they were very prompt to call and communicated the issue very thoroughly. Despite the complications they got everything done very quickly and for a fair and reasonable price. All in all 10 out of 10 service and highly recommend.

I don't normally leave reviews but these guys were too good for me not to. I was having some car troubles and had taken my car to a mechanic who recommended a new transmission which was going to set me back $6500. I wanted a second opinion and took it to Ace Transmission who did some testing and realized it was just a bad battery. They replaced it for $300 and it runs like new again. They could have told me the same thing as the other shop, but they didn't and I appreciate them for that.

I cannot express my gratitude for this place enough. They are the most compassionate and respectful place of business I’ve ever been to, and certainly the most honest mechanic you’ll ever visit. I’d trust these guys with my life. When my vehicle’s transmission gave out quite literally on the way to the shop, they told me straight up that it would be very expensive to rebuild. It was a high mileage vehicle anyways so we ended up selling the car, but they graciously allowed us to keep the vehicle on their lot while we decided. Great communication and very flexible.

I have never experienced this level of customer service! They were quick and efficient. They also kept me updated from start to finish!!! Do NOT go anywhere else!!!! Bring your car to Ace Transmission and know that you will be treated more than fairly!!! The entire staff was amazing!
