Hello, I wanted to…read moretake a moment and thank Mr John at Advanced Transmission Center. He went way above and beyond and took care of all of my questions quickly and thoroughly. He even added a touch of humor to break up the process a bit. it was very much appreciated. The technicians went through my truck and let me know it was something other than the transmission causing the problem for me. I'm grateful for their time and honesty. What was great is the team provided a FREE diagnostic on my transmission. A great value these days because most would charge to diagnose and apply the fee towards the repair. What a great service this repair center provides. John was able to recommend another repair shop that could take a look at my truck since it wasn't transmission related. I'm coming back soon for a differential fluid service and for a transfer case service. They also do these repairs too. Thank you very much Advanced Transmission. I will be back. Thank you

Mechanic recommended fixes for the long road trip, we had them completed and picked up the car with seemingly no issues. We were slated to leave the next morning at 5am, so we woke up at 3am to get ready and take the dog out on a walk, where we discovered the splash guard hanging completely on the ground underneath the car (first image + video below). So we had to delay our trip out by 2 hours just to bring it back in. Told them my frustrations with having our travel delayed, and wasn't really met with any sort of apology / compensation. Finally get back out on the road, and when we arrive at our destination the next morning, we noticed a scraping noise when hitting some low bumps. Looked under the car and see that part of the guard underneath is held together with a zip tie! (Second image + video) Absolutely insane work. Completely disgusted with the shoddy work and the lack of attention + care.

Admittedly, Stu is never someone that you want to need to call... but you are infinitely grateful for when you have to call! He has always been honest, upfront, and educational when I've needed repairs. I always appreciate the thorough reporting that I get when receiving estimates. Getting the run-down on both the immediate repair needs and what repairs/maintenance to anticipate in the future helped me take a car I expected to only last 6 months & made it run for another 2.5yrs. Over the years, his mechanics have prevented me from buying bad vehicles during pre-sale inspections. One time, Stu was able to diagnose a problem with my old jeep based on my description of an occasional noise and his trust in my intuition. No clue how he did it, but it was probably magic. Anyway, just save his number for when you need him!

Of course I dropped by to check out the place prior to making my decision. I wanted to make sure Tim wasn't packing a loaded gun as one post mentioned.I was impressed with the place as I took a tour. Tim seemed like a strait shooter- I was convinced they had the right stuff to fix my truck. It turned out to be a broken axle, instead of the tranny. They kept me updated on the progress... I needed to come by and grab a tool from my truck while it was up on the lift and they were very accommodating. Harold, who was doing the work was very pleasant and helpful, showing me the broken parts etc. The various front office staff were pleasant. My truck was finished in a timely manner. The bill seemed reasonable ( expensive repair? Of course it was expensive! its a transmission/powertrain shop, but I know it was done right). I'd give them my business again... I couldn't have asked for better service. Ron Lehman

Detroit Transmissions (Tim Tapper) Dropped my Mercedes off…read moreon April 1, 2026. They looked me in the eye and said 2-3 weeks. I finally got it back in July. They charged me for a "100,000-mile warranty." After the money cleared they said they'd mail it. Three weeks of complete silence later I called. Some bitter woman at the front desk swore she'd email it "immediately." 48 hours later -- still nothing. Called again and got the owner, Tim Tapper. He played stupid for a minute, then muttered, "Well, it takes me a long time to fill those out." You could hear him sounding out words like a slow child while he talked. They never filled the warranty out. Not a single word of it. They took the money, lied to my face, and spent an entire month gaslighting me because the owner is too lazy, too dishonest, and too incompetent to complete a one-page document. These people are morally bankrupt, thoroughly unethical, and as worthless as a cup of cold piss. Absolute bottom-of-the-barrel operation. Do not give them a single dollar.
