Happy Customers

“These guys are awesome! One of the few places you can still go and be treated like family. They don’t try to sell you something you don’t need, and if they do tell you that you need something, they will help you track down the best parts for your situation. They tell you like it is and there is no pressure to do anything you don’t feel comfortable with. Before you have your transmission serviced anywhere else, stop in and get a second opinion and estimate.”

“Took my 2005 Pontiac GTO in about 5 months ago with a blown transmission. These guys were fantastic! I do not trust easily when it comes to my car but felt at ease leaving it with Hydra-Tech. They explained everything in detail and even let me take a look at the failure point on my old transmission parts. The price was fair and although it took a short while for the work to be completed I was confident it was being done correctly. Would take any of my cars back to them in a heartbeat but hopefully it won’t be necessary!”
