    I needed a new valve body and solenoid pack for my 68RFE ASAP. Adair and the rest of the team at ATS had one built, tested and shipped to me in just a couple of days. Adair took plenty of time to answer my questions and kept me in the loop while my new valve body was being built. He even texted me with the tracking number once it shipped. He also tossed in the billet filter adapter for free. So I don't have to worry about the mopar plastic adapter breaking and grenading my transmission. The valve body and solenoid pack arrived well packaged and it was quick and easy to swap it out. I now have the peace of mind that I will be getting more life out of my transmission. I really appreciate how fast this was built, the advice, communication and the overnight shipping to ensure I could get my truck back on the road!

    I really appreciate the solution that Christian Brothers came up with for my air conditioning. I…read morehad lots of previous service and while it was expensive to replace the compressor, it was the answer that finally returned fresh chilled air to my vehicle, and now I am cruising along during this hot Colorado summer. I would feel comfortable returning with other issues on my vehicle in the future.

    Took my car in to get it checked for a "long distance road trip." Diagnostic alone costed $195,…read morewhich I thought was incredibly high compared to other locations I've done that at. Mechanic recommended fixes for the long road trip, we had them completed and picked up the car with seemingly no issues. We were slated to leave the next morning at 5am, so we woke up at 3am to get ready and take the dog out on a walk, where we discovered the splash guard hanging completely on the ground underneath the car (first image + video below). So we had to delay our trip out by 2 hours just to bring it back in. Told them my frustrations with having our travel delayed, and wasn't really met with any sort of apology / compensation. Finally get back out on the road, and when we arrive at our destination the next morning, we noticed a scraping noise when hitting some low bumps. Looked under the car and see that part of the guard underneath is held together with a zip tie! (Second image + video) Absolutely insane work. Completely disgusted with the shoddy work and the lack of attention + care.

    I had an oil change done here, and Christian Brothers truly impressed me. They pulled my car up,…read morekept me updated throughout the entire process, priced the service right in line with the local quick‑lube places, and even provided a full online inspection they walked me through in detail. The lobby was clean and comfortable while I waited, and those cookies they offer are a great touch -- it really feels like a breath of fresh air. I'll definitely be coming back.

    I don't usually go out of my way to write reviews like this, but my experience with Christian…read moreBrothers Automotive was so frustrating and disappointing that I feel obligated to warn others. From the start, everything felt off. What should have been a straightforward diagnostic turned into a bloated, overpriced "inspection" loaded with vague explanations and questionable recommendations. I went in expecting honesty and professionalism--I walked out feeling like I had just been taken advantage of. The pricing is absolutely outrageous for what you actually get. They charge premium rates, yet provide little to no transparency about what they're doing behind the scenes. Labor costs were inflated, parts were marked up well beyond reasonable levels, and the explanations I received felt more like rehearsed sales pitches than genuine mechanical advice. It became very clear, very quickly, that the goal wasn't to fix my vehicle--it was to upsell me on as many unnecessary services as possible. What really pushed this over the edge was how my truck was handled and what I was charged. I feel like my vehicle was completely mistreated while it was in their care, and on top of that, I was hit with a bill for nearly $1,700--and not a single repair was actually done. This was supposed to be a simple diagnostic that I was quoted around $250 for. Somehow that turned into almost seven times the amount, with nothing fixed. That's not just frustrating--it feels completely dishonest. What's worse is the lack of honesty. I was told I "urgently" needed repairs that, after getting a second opinion elsewhere, turned out to be either completely unnecessary or wildly exaggerated. That's not just frustrating--it's unacceptable. Trust is everything when it comes to auto repair, and I felt like that trust was completely violated. The whole experience left me questioning how many other customers have been pressured into paying for work they didn't actually need. It's one thing to charge a fair price for quality service--it's another to take advantage of people who rely on your expertise. If you value your time, your money, and your peace of mind, I strongly recommend getting a second opinion before agreeing to anything here--or better yet, just avoid the headache altogether and go somewhere that actually values honesty and integrity. I won't be returning, and I certainly won't be recommending them to anyone.
