Colorado Transmission & Diesel Specialists

I spent $10,000 here new injectors head gaskets and head studs and tuning, it took them 3 months to do the work. 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

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.

Have add my truck in there 4 times in the transmission still is not correct .Took the truck over to another transmission shop today will repost when I find out .Left my truck there ran fine as they rebuild the motor pick up a truck now the motor Knocks

Fell in these guys hands by desperation and didn't know what to expect. Let's just say I'm impressed. Had a problem with my mini van. Took it to the dealership and they looked at it all day and told me something was wrong with the transmission and to just take the loss and try to sell the car. That was a Ford dealers and they told me before hand that it'd be best to take it to Nissan since that's the brand. But the nearest Nissan dealer is too far from my town. So researched a transmission shop and call COLORADO TRANSMISSION and they told me to bring it in so they can see what's up. Took it there and wasn't in no rush. Next day they called me and told me it was an easy fix (easier than changing the while transmission) and the price was very fair. After the fix they called me and told me they wanted to keep the car and teat it out to make sure there wasn't something else making the sensor go bad. Luckily nothing else was bad and 3 days later (weed end included) the car is back to me. Will definitely be taking my next problem to them as they work on anything mechanical, aside from being transmission and diesel specialist. Happy customer. And these guys are the first shop I van say I trust since moving to Colorado 6 years ago. Give them a chance. You won't regret it.

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.
