Certified Transmission this Business is Fantastic!!! I took my 2018 Ford Fusion Titanium to them 5-28-2026. To check on a leak from my transmission underneath. Found out there was no visible leak. They cleaned it up underneath tested it. Drove it around let it set come to find out no leak. Didn’t even give me a bill. Great Business and Great people work here. If you think there’s a problem with your transmission take your vehicle to them. 😀
