These men rebuilt my transmission in my 2008 ram 3500 and I couldn't be happier. Took my truck to them expecting to be without it for at least 2 months like I had with other shops in the past but I am happy to say my truck was completely finished In about a week. Very professional. Excellent communication about the work. Also very knowledgeable about my particular vehicle. I would highly recommend Roadrunner to anyone needing transmission or diesel repair.

Roadrunner is the most well run and professional shop I have ever used. Super happy to have found these guys. Jim owns the place and is hands on in the company. Numerous times I have asked for services and been advised they were unnecessary. It's amazing to work with an ethical mechanic that is so trustworthy and amazing at what they do. Thanks guys!

Jim and Herby at Roadrunner took great care of me. I drive a 1999 F250 with a 7.3 powerstroke. It's getting harder and harder to find honest and reliable mechanics to work on my older vehicles. Luckily, I brought my truck to these guys and couldn't be happier with the work they did and the way they treated me as a customer. The repairs were great but the service was even better. Highly recommend.

Excellent service working with Jim and quick turnaround time. Had the transmission rebuilt and replaced in less than a week after having towed in. Very clear communication on what the issue was, total cost, and how quickly the work could be completed. Definitely would recommend to anyone needing transmission work

5 Stars, Exceptional Service! Jim, Mando and team bailed me out after getting the runaround at the dealership for a week on a transmission replacement on a Jeep Grand Cherokee. Their team sourced and installed the new transmission in under three days, where the dealer couldnt even source the parts. Great communication with providing/explaining quotes and keeping me informed through the entire repair process. Competitive and transparent pricing. Highly recommended. Thank you!

Took my Ford f 350 to Roadrunner, it wasn't running and was leaking oil. I needed a tune up also I was on my way out of town with my rv. Picked it up in about a week.We realized oil was still leaking so we took it back they fixed the hose that was causing the problem. Needless to say we got on the road made it to Texas and oil was squinting out everywhere back to the shop. Called roadrunner and he said he would pay for it to be fixed. Roadrunner stood by there word and refunded every penny we paid out to the new mechanic. No More Leaks. Thank you Roadrunner for you honest services.

This place is awesome! Jim is really professional, nice, and straight to the point. I took my 97 dodge diesel in to have the trans rebuilt and upgraded. Jim said 2-3 days and was on point. Dropped it off Tuesday morning picked it up Friday morning. The price was extremely fair. I plan to use Roadrunner in the future. It's worth the 1 hour 20 minute drive to get there.

Jim helped me and was very professional and efficient. I thought the pricing was perfect. No complaints at all. They fixed my transmission that was shifting hard and it’s perfect now. I would highly recommend and I will be returning with confidence if any other issues arise!

I have had 3 vehicles serviced with Jim & Randy at Roadrunner. 2 of those services were complete transmission rebuilds. I know enough about vehicle service to drive Jim & Randy a little crazy but found them to be very direct, honest and ethical. For the transmission rebulds, I had done some homework to investigate issues and improvements over the stock factory transmissions for these vehicles. When I initially talked to Jim, I asked him what improvements could be made to the transmissions and he hit every major design flaw and what he does on his rebuilds to improve the performance. I knew right then and there Roadrunner was the place for me. Any issues I have had with the work was discussed and adressed to my satisfaction. They are professionals who truly care about thier customers and doing good work. I stopped by unannounced to check in on the repairs and Jim would take me in the shop to show me what was going on. I cant think of a better way to communicate the status of the repair and exactly whats going on than to see it with my own two eyes. Thier communication was outstanding. I do a lot of repairs on my own and will only use Roadrunner for the repairs I cant do or dont have time for. I would recomend Roadrunner to any family or friends for work on thier vehicles.

I've gone to these guys twice now for problems with my Jeep, and I'm very grateful to have found such a trustworthy and knowledgeable shop. My dad is a mechanic so I know enough to be dangerous, and every time these guys are straight up and do not BS. I'm grateful to have found a shop like theirs in Denver and would recommend them to anyone.

Rebuilt a transmission by them last year costing $5500. Less than 5,000 miles ran on the truck and it already gives me problems. Costing me $1000 to fix. I have to say that working with other diesel mechanics and driving it after fixing that part. I have to change this up a little. Towed my trailer to Houston Texas and back with no problems. The tranny is still holding strong. Still upset but they are a lot better with what I’ve been dealing with these past years. Changed my star from 1 to a 3 because they did a terrific job after I fixed that part.

Roadrunner Transmission is the only shop to call if you’re looking for honesty, integrity and superb customer service. I brought my car in thinking it was either going to be a new transmission or catalytic converter-neither were in my budget! They diagnosed that it was the turbos. Still a pricey replacement. Parts were ordered but when they got in there to start the disassembly they found that a clamp had failed. Reattached the turbos and called to give me the good news! The parts were returned to the warehouse! I highly recommend this shop! Randy and Charley are the best, give them the opportunity to do you right! You won’t be disappointed either.

These guys are honest. I value that. Had another shop wrenching my 7.3 and the other shop tried to charge me 2k just to do seals on a bad transfer case, pulled my truck out of that shop and brought to roadrunner. They had my truck back to me in 2 days and helped me navigate the dishonesty of the other shop. Thanks for helping guys. You have my fleet in future Wes Benson Abraham Benson Roofing LLC

I own a 1998 Toyota 4Runner that needed a new clutch. Jim their was a huge help, understood what I was trying to accomplish and kept me in the loop the whole way. Got the job done the next day and for half the price. Big shot out to Jim. #1 4runner’s of Colorado suggested transmission shop.

I was in Centennial for only a few days and needed a fuel filter replaced in my GMC Denali. I was able to get my vehicle in and back on the same day I called. Very professional and knowledgable. I have total confidence in this team and will be back.

Don't go to this place I called to get a price on a new transaction I spoke with the owner give him all my vehicle information he told me "I can't give you a quote over the phone and to bring it in" I told him I just wanted a idea of cost and wanted a ballpark idea of cost to see if it's worth it to get fixed his response was (it could be $5 or $10000 I Don't know without seeing the car and need to do a diagnosis) I informed him that the vehicle is not drivable and just wanted an idea of cost to fix the car. He said bring it in, bring it in. I told him just want to get a quote. He was very rude cursed at me and hung up. Do not go to this person. They will scam you into paying for a diagnostic or something. You already know what's going on. Very rude disrespectful
