Auto Repair
in Fort Lupton, CO

Just needed to say how great these guys are. I am so impressed with this shop — they rebuilt my 10-speed automatic in my truck and it runs perfect.

Peter and the crew were very professional. They fixed my car and got me back on the road at a great price!

These guys know what they are doing! Excellent service, my truck is back on the road and driving great, thanks!

I can't express how satisfied I am with the attitude, helpfulness, honesty and friendliness I experienced dealing with this shop.

Doug runs this place in tip-top shape. Very honest and knowledgeable crew. They stand behind their work. My dad has used them for years.

Amazing service. Quality work — you can tell these guys are experienced. Very professional, I won't take my truck anywhere else.

Thoroughly pleased with their work. Easy to communicate with, got my transmission changed in just a couple of days.

Super nice owner. They were speedy and kind. Thank you!

Doug and his staff are some of the most honest and straightforward people in the industry. I have had two major repairs done here.

I'm a small business — I rely on my truck 100%, putting 5k a month on it. If I have a problem they get it in as fast as they can.

The staff at Colorado Transmission & Diesel Specialists showed exceptional honesty, friendliness, and courtesy.

All I ever got here is great service.

Doug helped me out after another transmission shop did a terrible job. Done a great job, never been happier.

Doug and his guys make a great shop. I have had a lot of work done here. The service has been great. Highly recommend.

I do not usually put reviews on websites but I wanted to share with everyone what a great job the guys at Colorado Transmission did.

My overall experience was very positive. I called in with my concern about my differential. They guided me through the process.

Doug and his team are great to work with. Doug has rebuilt all my transmissions, from my race transmission to my daily driver.

The only place I will take my vehicles to be serviced! Honest, trustworthy & super professional business. Keep up the great work.

I took my Acura into this shop for some mechanical issues. I was nervous about the cost — the owner took the time to walk me through it.

Brought pickup for repairs. In and out in 3 days. Will be coming back with all repairs I need. Awesome crew.

Repaired our 1992 Jeep master cylinder on short notice. Good to work with, fair price.

Always helpful.

Doug was absolutely fantastic to work with. He actually picks up the phone and is happy to answer any and all crazy questions.

Smart, honest mechanics. Helped me on my diesel truck and saved me money over the corporate dealership.
