Roadrunner Transmission and Diesel, Centennial CO

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!

These guys will take good care of you here! This is a small local business ran by good people.

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. They don’t do what you ask. They just want your money. Not going back for sure.

Awesome service while I was traveling and had a fuel line issue with my Powerstroke 7.3L diesel. Mondo and crew were able to get me in and out in less then 3 hours, they even had to have the fuel line built in that time. Great work! Highly recommend for diesel engine work!

These guys know what they are doing. Mondo and the crew will get you taken care of. They were priced great and they had the job done super quick. Will be back.

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

Me and my family have been taking our cars to Jim here at Roadrunner for years since we have first moved here years ago. I couldn’t be more thankful for the fact that he has been there for years to help us all out. I hope anyone that is looking for a good local shop and even better mechanic to take their stuff brings their cars here. Thank you for all of the help Jim!

Jim Jones is not only a top notch transmission mechanic, but an incredible person. He is kind, compassionate, honest, and works fast. My new car had a transmission that was failing and he worked with the warranty company and got my car done an entire week ahead of schedule. Anyone that needs work done, please see Jim Jones at Roadrunner Transmission and Diesel.

Jim and Jesus are amazing. Fast turnaround on my F350. Great pricies, will definitely use them again.

Review Update- The second shop I took it to did not do a thorough inspection and it’s clear my transmission is failing. Roadrunner gave me a correct diagnosis the first time.
