Doug and his Colorado Transmission & Diesel Specialists team has some of the best auto repair mechanics in Fort Lupton and really all of north Denver Metro Colorado for that matter. My 2500 dodge ram high top conversion van would not go in reverse all the time. At all the other auto repair shops thy all said our vehicle needed a new transmission replacement $$$. The automotive repair techs at CTDS did diagnostic testing and found out we just needed a wire harness near the torque converter replaced. If I had listened to other shops it would have cost thousands to replace the tranny. With the savings, I decided to repair the wiring, get oil change, engine tuneup, and all around brake job it needed. Having over 235k on my van I knew eventually would need a new transmission install with its high mileage and when it did Doug gave me a good price better than all other transmission shops in Denver or Brighton it was worth driving up to him for tge service abd savings. They demonstrated unwavering honesty in their auto repair services, courtesy, high-quality work that is why I chose CTDS and imho the top-tier automotive repair shop near my house in Thornton, CO ..... come to them first before you go anywhere else at least to diagnose yur problem you will be glad you did like I was!

Excellent company!!! Had these folks do a front diff adjustment on my 2001 grand cherokee and they did an outstanding job. They also found a couple other items that I did not notice after completing an axle swap. Will for sure be using these guys moving forward.
