Had some concerns about my half ton GMC transmissin was operating, so went in and asked for a diagnostic test. First off, Kim and CJ at the front desk were super nice, and definitely no attitudes like you get at some shops. Within just a couple of minutes they had Danny, who I assume was their Super Tech, come out some he could take it on a test drive. Danny asked me questions as he hooked up he computer, and then we were off. Fortunately, all the readings were normal. Danny was very patient and explained to me a little about how this specific transmission operated which may be what I was seeing and feeling. The other big help was he explained what kind of early symptoms to look for, and if those occurred, to bring it back right away to avoid more catastrophic problems. We got back from the test drive, and I was good to go. No Charge! Can't get better than that. I will definitely be recommending them to friends.
