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

Took my car in to get it checked for a "long distance road trip." Diagnostic alone costed $195,…read morewhich I thought was incredibly high compared to other locations I've done that at. 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.

DISHONEST MANAGEMENT and ZERO ACCOUNTABILITY. In Oct 2024,…read moreDetroit Transmission replaced our Ram's flex plate with a Mopar OEM part. By June 2025, the part failed. Tim repeatedly claimed it was out of warranty due to mileage (over 15k miles) and charged us $2,576 for a second replacement. I did the legwork Tim refused to do: I verified with three other shops and two Dodge dealers that the Mopar part actually has a 2-year UNLIMITED mileage warranty. The part was found to be warped with cracked welds. I also found out we should have been charge $798 for the part, because mechanic shops get a 30% discount from the Dodge dealer. After I provided the warranty proof and asked why he changed $1238.51 for a $798 part, Tim admitted to a "computer error" overcharge for the part of $440 and refunded us the $440, but the nightmare continued. Though their Dodge dealer credited Detroit Transmission for the flex plate on Nov 5 and mailed a labor reimbursement check on Dec 26, the shop still did not reimburse us. When we finally confronted them in person in Jan 2026, they refused to give us the full refund for the part. They charged us $798 for the part and only refunded $638.40, pocketing $159.60 (their shop discount for the part). They also refused to refund the $150 of labor reimbursement and $113.32 sales tax. They still owe us $422.92. They forced us to do all the warranty legwork ourselves, with Cathy, the bookkeeper, saying that was our responsibility since it was our truck. They kept money that belongs to us. AVOID this shop; they do not honor warranties and lack basic integrity. For a more detailed review check out their Facebook page.
