“What a great experience! Coming home from the deer lease this week-end, my Chevy 2500 diesel w/ Allison transmission starting making a high-pitched noise. I didn't know any transmission folks, but knew I didn't want just anyone working on my truck, so off to the internet I went. I found Certified Transmissions, read the reviews, and thought it was worth a call. I called and talked to Charlie, who asked the right questions, so right away I knew I was talking to a real mechanic. So I took my truck in, and Charlie listened to the truck, and before he even drove it, told me it wasn't the transmission, it was the power steering pump. Same kind of whine, but a much cheaper problem. He fixed it in less than a day, was very reasonable in price and got me back on the road. Although I didn't know it at the time, they do all kinds of auto repair, so I have found my new mechanic. I swear, it felt like throw-back to when you could trust your mechanic to treat you right. Thank you, Charlie! We will be back.”
