I recently purchased a classic 1995 Ford F-250 with 172k miles that had been through the wringer as an East Coast snowplow truck. After doing a ton of research, I called AC Transmission and they took the time to walk me through exactly what they would do, including best/worst case scenarios and a realistic price range. From the first phone call I could tell they were passionate, knowledgeable, and genuinely excited to help. Their communication throughout the process was excellent. During disassembly of transmission they showed me what was wrong and what needed fixed (basically everything). Their overall professionalism and quick turnaround were also stellar. It ended up needing a full rebuild — they rebuilt the entire transmission, used an NOS original case from their inventory, and essentially replaced everything. They had it back up and running in about a week. I drove it 90 miles home and it performed like a brand-new truck. Huge thanks to AC Transmission and the entire team. Highly recommend!

I can’t say enough great things about AC Transmission—they truly exceeded every expectation! From my very first phone call with Mike, who was incredibly friendly, knowledgeable, and felt like chatting with a buddy, I knew I was in good hands. The entire team was professional, upfront, and transparent about everything, which I really appreciate in this industry. They demonstrated deep expertise with my Ford and its transmission issues right away, putting me completely at ease leaving my truck with them. They took the time to clearly explain the problems, walk me through their repair plan, and answer all my questions—no rush, no pressure. Compared to the Ford dealership’s quote (sky-high price and a ridiculous 2-month wait), AC Transmission saved me a significant amount of money and had my truck fully rebuilt and back on the road in just 5 days—from drop-off to pickup. That kind of speed and quality is hard to beat! These guys are the real deal, honest, skilled, and genuinely customer-focused. If your vehicle is having transmission trouble (or any issues), do yourself a favor and give AC Transmission a call. I promise you’ll be taken care of exceptionally well. Highly, highly recommended!

I stopped by recently because my car was having an electrical issue that turned out to be related to the alternator. Chris and Derek were both extremely helpful and took the time to point me in the right direction even though it wasn’t exactly a transmission problem. They were honest, easy to talk to, and didn’t try to push anything I didn’t need. It’s always a relief finding a shop that treats people fairly. Really appreciate the help from the AC Transmission team.

Wow, Amazing service, above and beyond my expectations. I brought in my Grand Cherokee with a troubling driveline noise that my usual mechanic couldn't identify. The guys at AC diagnosed it, at no charge, as a bad driveshaft. They could have easily told me it was several more expensive issues and I wouldn't have known better, but they were straightforward about it all. After the repair was completed, I noticed a new driveline issue, so I brought it back the next day. They didn't give me any hassles at all, checked it out, and isolated it to a defective part, so they replaced it again. This time it's as good as new! I'm beyond impressed with their honesty and commitment to doing the job right, and at a price less than I expected. I highly recommend AC Transmission for any auto repairs. I'll definitely be back if I ever need any work done

I called AC Transmission based on their great google reviews, they were all accurate. From the first call to discuss my transmission problem to picking up the truck when it was finished the experience was exceptional. Chris and Mike were friendly, knowledgeable and explained the entire process before I had my truck towed in for repair. The quality of the work was excellent, the repair was completed on time and the price was fair.

Chris at AC Transmission is one of the most stand up and honest mechanics I have ever met. The team at AC worked on my 2006 Chevy Silverado (250,000+ miles) and have stood by their work everytime I've needed help. Most recently, Chris stayed after hours just to make sure my truck was delivered by tow, and called me to ease my mind that my vehicle was in good hands and safe. Thanks to Chris and all the guys at AC, you are experts at what you do, but better at how you treat your customers.

I own a Hyundai 2015 and needed to have my transmission repaired before. After finding the shop that serviced it before is no longer in service. I went on the hunt to find another shop to service my transmission which is required. Luckily , I found “ AC Transmission “ they had a lot of positive reviews which tweaked my interest. I contacted “AC Transmission “ and they were friendly and easy to talk too. As I was a senior citizen worried about cost. After talking with Mike and Chris they explained they were going to do a diagnostic to see if everything was in good working order and for no charge! Well as luck would have it everything was fine and as promised no charge. I appreciate that kind of honesty and would highly recommend this shop.

These guys are awesome. Brought them my F150 which was doing all the things that would make you think the transmission was going. They evaluated it (for free), and found an engine issue, not the transmission. They called me immediately and sent me their very thorough inspection. Could have easily sold me a bunch of transmission work. They aren’t kidding when they say “Denver’s most honest transmission” shop and I’m very appreciative of that!

We could like to share our sincere appreciation to the AC Transmission staff located at 6780 Federal Boulevard, Denver CO 80221. We took our vehicle there to have the transmission rebuilt based on previous comments from customers who had their vehicles serviced there. The customer comments we reviewed were positive and the overall recommendations were influential in making the decision to have our vehicle serviced at the AC Transmission Center at that location. The staff we worked with were courteous & professional, and as a result we immediately scheduled our vehicle for diagnostics and repair. The results of the diagnostics were shared with us allowing an opportunity to review the scope of work and approve everything before any work was started and completed. The estimated cost of the repairs were provided in a detailed document describing the overall work required as a result of the diagnostics so we had a good understanding of what to expect. After the new transmission was completed, we returned the vehicle due to some trouble codes that appeared after we picked up the vehicle. The owner, Chris Saykally, spoke with us and stated out of customer loyalty and appreciation they would research the trouble codes and contact us upon understanding what was wrong with our vehicle outside of the scope of transmission rebuild that had been completed previously. Many work hours were spent by the electrical expert and other staff members, who ultimately discovered what was causing the trouble codes that we had experienced after a thorough vehicle inspection was completed. Ultimately, the issue was not related to the rebuilt transmission rather part of the electrical system. All of the vehicle defective 02 Sensors were replaced, checked and reported as working correctly. Chris indicated they would not charge us for the additional labor because they wanted to ensure customers have exceptional service and experience their appreciation for our patronage. As a result, we would like to share our positive experience working with AC Transmission Center and highly recommend their service to anyone needing transmission work. We will make sure to share our exceptional experience with our family and friends because we were treated with respect, and ongoing follow-up and timely resolution overall. Mike and Judy Najera Brighton, Colorado

My husband brought in his 2005 F-150 to diagnose a leak. It turns out that it wasn't a transmission leak but an oil pan leak. They cleaned it thoroughly to determine this and made a recommendation for repair since they specialize in transmissions. They would not accept any payment for their time. Everyone is very friendly and completely honest! The shop is immaculate. And when you call you get to talk to a real person not to an answering machine. Thank you for your great service to the community!

Man. Where do I begin. Chris and his team are 1,000% genuine since day 1. They kept me informed of every move they made from when it got there, filing the claim, taking the trans out and to installing the new one. The team that they have are awesome. I love these guys. Communication, understanding, and did what they had to do to the T and dotted there I’s. If I had the money, I would take these guys out to eat, all on me. Thank you AC Transmission and great work you guys. Forever in my prayers and many more trans to go. 🤣🤣👍🏿👍🏿👍🏿👌🏿👌🏿👌🏿

I brought my 2003 Chevy Silverado in for a transmission rebuild after it started slipping and wouldn’t shift past 2nd gear. The shop did a thorough diagnostic before starting work, explained the options clearly, and kept me updated throughout the process. Pricing was more than fair for the amount of work involved, and they offer a great warranty in the rebuilt transmission. Overall, I’m really satisfied with the workmanship and communication. Chris and Derek were great. It’s nice to deal with a shop that still takes pride in doing things right.

These guys are simply the best. They are so thorough, communicate everything, and actually look out for their customers (unheard of these days). They focus on finding the problem and solving it, not just taking your money (also unheard of). I won’t take my truck anywhere else in Denver from here on out. 10/10 do recommend

Absolutely the best mechanic shop available!!! Very honest and thorough! They handle the major problems for my work and personal vans. For minor stuff, brakes, alignment, injectors etc, AC recommended 303 Alignment and auto on 64th and Sheridan, another very honest shop that operates at the same high standards!! Between the two shops my vehicles are always in great shape!!!

Unbelievably, even out of the warranty time-period, these guys fully covered their part when it failed within 300 miles. I feel any other business would’ve refused to cover it due to the technicality (expired warranty time limit). Going above and beyond to make sure we were taken care of came at a significant cost to them. This business clearly has an extremely rare commitment to integrity. My wife and I have agreed that we will use this business exclusively, even if it is more expensive than others. Their attitudes are top-notch and their commitment to honesty and customer satisfaction is unmatched. I can honestly say they represent humanity with true distinction.

Unbelievably Honest and Professional! After my 2020 GMC Sierra's transmission failed, the dealership gave me a heart-stopping estimate. I called AC Transmission for a second opinion and spoke with Derek. What a difference! He was incredibly knowledgeable, walked me through his diagnostic process step-by-step, and even arranged the tow from the dealership. He built immediate trust and didn't make me feel like just a paycheck. While a last-minute coverage offer from the dealership meant I didn't end up needing their repair service, I would not hesitate for a second to recommend Derek and AC Transmission. If you need honest, expert transmission help, this is the place.
