Differential repair service near Boulder, CO

Well worth the wait... Very busy shop! We had our transmission fail this last weekend. ATEC was not able to get to us for a few days during the snow storm that hit Denver last week. After many attempts we finally got through to them as we found out they had been without power for two day's. We had a friend give us the phone number and we almost gave up waiting to get them to call us back. At first we got upset leaving messages and no return call. We are so glad to get to use this shop and getting to see why so many people are using them. We will be back and thanks to the girl at the front they call her Jes. She kept us up to date with great communications. I recommend this shop and say this with gratitude to them as i could have spent a lot more then they charged to get my vehicle back on the road.

They did a great job. They even took me back there so I can see what they are talking about. I usually hate going to get car serviced, but these guys made the experience less painful. Tammy Hesser

Ken Hall in the last week- Just had my 2005 Dodge Ram engine completely rebuilt. Took a bit longer than expected, but well worth the wait. It has never run better, even as new. Picked it up Friday, and headed straight for elk camp. The increased power is amazing. I am getting 3 miles more per gallon, and that's with only 500 miles on it thus far. These guys really know their stuff. I would highly recommend then for anyone needing diesel or auto service.

.Always top notch mechanic experience
