Auto Tech and Transmission LLC

Brought my car in to have a diagnostic run in order to fix a code. I rebuilt the entire engine with all OEM parts. The gentlemen in here over torqued my valve cover cracking it and my intake so tight im lucky my head wasnt stripped out.They tried to blame heat expansion after I had just driven a 3 hour drive with absolutely no issues prior to bringing it in. They sabotaged my whole car loosening my hose clamps and my ground connections. I left their lot and car would not stay running. Chugging and eventually not starting at all. Upon my own inspection I found 7 loose connections and 4 over torqued bolts that in no way could have been there on my three hour drive previously. There's no way that they overtured, by at least twenty foot pounds from heat expansion on only three random bolts on my intake, and four on my valve cover. They torqued down my valve cover so hard. The seal was ripped into and they put so much pressure through my car. Doing a smoke test that they blew out my timing a seal and a bunch of other seals trying to find the crack they caused over tightening the valve cover bolts. They put my life in danger, sending me out of there in a compromised vehicle. NEVER LET THEM UNDER YOUR HOOD. they will tell you whatever they have 22 get you to look at this, let them work on your car. When they can't figure it out, they try to turn it on you to save face. They call themselves master technicians, but I've never been to school to be an automechanic yet.I had to fix my car twice after leaving their shop. After paying $600 for diagnostic tests, I had to diagnose it and fix it myself, and fix extra stuff that they caused.

Literally saved me from having to buy anothe car… Took my car in as a last ditch effort to see if they could diagnose what I thought was a transmission issue. Dave and the guys at Auto Tech exceeded expectation. They thoroughly looked over the car and after a few days narrowed it down to worn out and mismatched tires (took it to another shot and they just took my money and told me the same thing I told them…transmission issue). Dave and his crew drove the car and evaluated every system and was able to pinpoint the issue. Bought new tires and the car is working fine. These guys are awesome and are really good at what they do!

Dave and his team have seen every car my family has owned since I was a kid, including my own car now that I’m grown. Very honest, goes above and beyond to locate parts, and clearly explains diagnostics in a way that’s easy to understand. We’ve always trusted him with our vehicles and I drove back into town from DeKalb just to bring them my car. Highly recommend.
