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.

I took my Acura into this shop for some mechanical issues, I have as nervous about the cost. The owner took the time out to come and talk to me personally about what was wrong with my vehicle. Ended up not being as bad as I thought, The technicians were very attentive and did a great job with my Acura MDX, I highly recommend this shop to everyone I know.

I tried to use this shop for a possible leak from my transmission; recommended by the shop that noticed the leak. They had my car for 12 days with no communication other than me calling them. No estimate on cost of work. They also told me that my front and rear transfer cases were leaking and the power steering system was leaking. After 12 days of nothing - no work, no estimate, no communication other than me calling them, I picked my car up and took it to my regular mechanic who just told me that the power steering is not leaking, the front transfer case is seeping, not leaking and not an urgent fix.This company told me 900 times that they are busy and that they are honest, in fact the most honest people out there. I honestly don't believe that.Service: Transmission repair

Doug was absolutely fantastic to work with. He actually picks up the phone and is happy to answer any and all crazy questions I have. I had him rebuild a 4r100 transmission and replace a water pump/fan clutch on my 2000 f550 and shifts and runs beautifully now. My truck has all sorts of other known issues and I'll definitely be taking it back here.Service: Transmission

I've worked with Doug at CT&D for years now from rebuilding the transmission in my 2001 Ford Harley Truck, a complete check out of my 2002 Duramax Chev. to today when I came in panicking about a fuel leak that was going to make me cancel a trip planned for over a year that starts tomorrow! The guys tracked down the part I needed and got me fixed up the SAME day! I can't thanks or recommend them enoughService: Engine repair

Took my car here to get my water pump fixed and the guys were so helpful! I felt that they were honest and caring. I was comfortable talking to them about what I needed fixed and they were very thorough. My car is running great and I've had no problems. So thankful for this shop and if I ever run into car problems in the future I will be back!

I took my car into this place of business because of a referral from a friend. I was quite leery do to the reviews. But have had nothing but trouble trying to get my Audi s6 working properly had transmission work done by another facility and it has never worked right from the time I got it back. So I counted my losses and took it to these guys to have transmission work done and I am letting you know what a wonderful experience it was. They had my vehicle done in a very short time and it works better now than when I first bought it brand new. Very knowledgeable, polite and professional if you have any type of car problem call them let them take care of you it will be worth it

Doug has worked on many of my vehicles over the past 20+ years. Anything from basic problems, 2500 Dodge Diesel issues, to ALL my transmission work, I've never been disappointed. He always gets me the right repair at an exceptional rate. I can call him whenever I have an issue. I travel from Wyoming to bring him my vehicle problems even if they have to travel by flatbed. Doug is the only one I trust to work on any of my vehicles. I have sent my friends and family to him too, they've always been happy with their vehicle results. Keep up the good work CTDS

Super service and quality of work. Doug is the best in the region. They stand behind their work and don't overcharge. You get first class repairs at great prices.CTDS has done such an amazing job for so many years they bring customers all the way from northeast Wyoming to do all repairs on their fleet vehicles. That says a lot about how great they are.Great job!!!!

STAY AWAY! They'll rip you off!!! Very bad experience here. Had a head gasket go out and took it to them. After they repaired it and said they rebuilt the head(so they say) it has been nothing but trouble. Been back to their shop 3 times now and it's about to back again. First time i got it back they did not tell it will need to come back for a valve adjustment after 500 miles. I drove it and it was making a tapping noise. After a couple hunting trips and 1000 miles later i called them back and told them about the issue. "Sorry we forgot to tell you to bring it back for a valve adjustment." So i took back and they said they adjusted the valves, but i still hear a tapping noise(wasn't there before i took it to them). Its not as bad, but still noticeable. Next trip out the truck dies about 50 miles away from home. I get out and there is oil everywhere so I pop the hood and my battery cables have burned off and it's leaking oil all over underneath my truck. I check the dipstick and there is barely any oil. Could have been dangerous had the engine blew going 75 mph down the hwy. They claim the battery connections broke off because it had a weak connection from not servicing the terminals. Really? The terminals look clean and nothing wrong with it. I didn't have this issue ever until i got it back from your shop. In the process my side mirror got cracked and they deny responsibility. They didn't even bother to clean the huge oil mess it made under my truck from the bad valve cover gasket. They are not professional and the owner himself will not hold himself accountable. I tried calling and talking to the owner, but of course he didn't have the integrity to even talk or call me back. Just told his messenger to tell me, "we're not responsible for damages." What kind of a crap shop are you running. I always paid on time and have paid almost $10,000 to this crap shop. Maybe it's time i steer clear of domestic vehicles and go imports only. Owning domestic vehicles has been nothing but trouble.

I own a 2003 Chrysler Concorde 2.7 V6 with a 42LE Transmission.- Peter Van Watermeulen, Ft. Lupton COBest transmission shop I've seen hands down. I'll break down each part into sections, customer service, mechanic services, quality of service.First time I called, Ray answered the phone. He is a wonderful guy and even talked with me about things other than automotive and was extremely pleasant. They actually care about the customer. Even when I called again Doug was super awesome and helpful. Both very knowledgeable people.I brought my car to this wonderful shop and they got me hooked up right away. I had looked into my car problem for several days online and ordered the parts that I would have needed and brought them in. My car was fixed in a timely manner, they kept me informed all along the way.Joey was my mechanic and he did a great job on the work with the car. He replaced my solenoid pack, and tested everything.They even returned the old parts, if I wanted them, and to show that they replaced it with the parts I had given them. Explained to me completely what was done to the car and what was tested. Car was returned clean and neat, exactly as I had left it.I definitely will be coming back for transmission work in the future.

I had to call them they got back to me twice I ve had to pull my number #8 injector because the o ring was destroyed and no copper washer on the nozzle of the injector I have the low coolant light all the time It came out of the shop and I ve had to fix multiple issues myself I had a diesel leak instantly once I got the truck back bolts and nuts missing on fuel lines and this shop doesn t seem to care I ll go elsewhere and pay more money for quality work i can trust. Money wasted and a whole bunch of issues

Truck lost half it s power while towing 15000 pounds and I was 3500 miles from home. Called a couple shops that just told me to bad we are booking appointments 3-7 days out you need to sit and wait. Called these guys late afternoon and they had me bring it in first thing the next morning. These guys worked hard to get my truck back running and then the diesel tech had me take it for a test drive with him in the truck to make sure it was back to performing to my expectations. First shop I ve ever had take the time to do that. I can t thank Ray, Doug, and Duane enough for getting me back on the road. Also Ray took time out of his day to call me the next day to make sure everything was operating good. If only more shops operated at this level of service

Honest. I had coolant dripping from the head gasket and was half convinced the head gasket had blown when I pulled into Colorado transmission and diesel. They pressure tested and found the heater control valve was leaking and running down to drip off the head gasket. They had me fixed and on the road in 3 hrs... these guys know what they're doing and are honest. They've earned a new customer today.

I want to be as fair as I can be considering the circumstances. I brought my 2011 Ram 2500 turbo diesel to CTDS on 11-10-2017 for routine maintemnance. Trans service, coolant flush, front and rear diffs, and transfer case service. I told the owner that I needed to truck back by 11-17-2017, giving him an entire week for the service work. He told me that it would not be a problem and that he would have it done and would call me to pick it up. I was in London the whole week and he never called. When I went to pick up my truck on Monday 11-20-2017, it was still not finished. I had to go back several hours later to pick it up. When I did pick it up, the roughly $500-$600 he told me it would cost ended up being over $800. I can't do business with someone like this, nor can I recommend this company based on this experience. Very unprofessional in my opinion.

I worked with these guys on my Ford that I have had many issues with. I had the truck at another Diesel shop that kept nickel and diming me to the death. I had the truck towed over to this shop. When everything was done the owner himself called me up. And I was very pleased with what he had to say. This owner and company are full of integrity and I am extremely pleased with how they helped me out. Thank you again. I will refer everyone i know your way!

DO NOT TRUST THESE GUYS! THEY ARE NOT HONEST AND OVER CHARGED MY BROTHER! When looking to get work done on your car run in the complete other direction. They broke my brothers Jeep and then had him buying parts left and right telling him that it would make his Jeep run. His Jeep was working fine before and took it in for simple maintenance and now his Jeep isn't working at all. These guys are crooks and take advantage!Services: General repairs & maintenance, Auto engine tuning

I recently took my 2004 Dodge Ram 1500 in to figure out why my truck kept dying. They were quick at diagnosing the problem and found out that the throttle body was sticking. So they replaced it. And I had my truck back in a couple days. And I haven't had any problems since. I highly recommend this automotive shop.

Over the past 3 years I've taken my Escalade here twice, once was due to a sensor that had to be replaced and recently had a service suspension system message which they figured what the problem was and fixed it. Shout out to Doug who was very informative when explaining what was wrong. Will be my go to spot for when my ride has problems

Had my 2004 Chevy 3500 with the allison transmission rebuilt by these guys i can not say enough good about them Doug is the best transmission guy i have ever talked to. I had work done on it before by several shops around town and the last was a suncoast. Doug showed me everythijng wrong with it and why suncoast, patc and most other shops transmissions dont last. Bottom line there cheap when it comes to putting parts in, but they will stick it to you on cost. My transmission that Doug built gained me 75 ft lbs torque and 50hp not bad glad i got rid of that suncoast. Also they were less than anyone ive had rebuild it before and much better.I am Mike Springs and this is the best shop for any type of work you need done call them save yourself alot of misery

I brought my car in to get a new clutch and they where awesome. So I decided to bring my truck in because it had a lot of rattles and they not only fixed everything but then didn t charge me a thing. I highly recommend these guys to everyone.Services: Transmission, General repairs & maintenanceServices: Transmission, General repairs & maintenance

Nothing short of a great experience! Doug and Crew perform great work in the shop and I cant say enough good for them. They know what they are doing is hard work, and they maintain to be very professional.If people are dropping $6k in work on vehicles these days, it shows they shouldnt have a drivers license, as they cant maintain anything. Then to post harsh comments is nothing short of trolling a business to harm them is poor sportsmanship on their part. Grow up and move on with life.

These guys were really awesome! They diagnosed and repaired my old car. They were reasonable and did what they said they were going to do.Luckily my fix was a few sensors and cables, not a total tranny overhaul!Will definitely be back if I need future repairs!

They were able to fix a problem on my diesel truck that other shops couldn't diagnose and fix. Great work and up front honest pricing.
