I came from NY to pick up a truck I purchased from a private seller. The transmission blew 30 miles into our trip home. I googled some transmission shops around the area and found advanced transmissions. It was almost closing time for them, but one of the guys said he would stick around until the tow truck could delivery the truck. When I arrived he went over all of the options and advised me on the best way to proceed. I then went back to NY and waited for the truck to get fixed. They kept me updated with the progress and when it was finished we worked out a plan to pick it up on a Saturday. The truck drove home perfectly 750 miles. They also check all my fluids and looked it over for my trip. I'm very grateful I came across this shop in such a time of debacle. Thanks so much!

I recently took my SUV to Advance Transmissions based on a diagnostics from Firestone that lead me to believe a catastrophic issue with my transmission. The transmission was a rebuild and was only a few years old, so still under warranty. After calling around to a few shops, some would honor the warranty while some would not, I ended up taking it to Advance Transmissions based on the fact that they would service it under warranty and were the most responsive. I'm really glad I did. I can't say things would have been worse at other shops, but I could totally see being taken advantage of elsewhere. The issue stemmed from a single missing o-ring. They had it assessed, replaced, tested, and ready in a day or two. And since it was such a simple fix, they made it free of charge. It was originally looking like it would be a lot of labor expense even if the part was under warranty. But instead, they were honest, courteous, and respected me as a customer. I'll definitely be taking any future business here.
One of the most honest auto repair shops I’ve ever seen. I worked with John. I told him my problem and over the phone. He helped me get my transmission working again saving me thousands of dollars I would highly recommend this transmission shop and the staff.
