I called several times and finally heard back that they could not get to it. On Wednesday they said that my transmission was ok and they needed more time to diagnose it. I told them I had to have it back by Friday to drive back to Texas. Thursday they told me that it needed new catalytic converters and some of the parts were in Denver and if they could get them delivered on Friday they would get it fixed. I told them that I would get them from Denver if needed. They said they would call me first thing Friday morning. I did not hear anything and started calling at 8:30. Finally when I called for the third time at 12:38 he texted me that he would call me right back. At 1:18 he called back to tell me that he could not get the parts until Saturday and they could put them on Monday. I told him that I had to come get it. He charged me for 4 hours at $160 an hour and did not give me a report because his computer was down. Would not give my keys until he ran my card or gave him $500 cash or $660 on my card. So he used extortion for me to get my truck. Hope he didn't pocket the cash. No diagnostic report or explanation of what he did for four hours. Very unprofessional and unorganized.

Since we were on our way home to Denver, this was immensely helpful to narrow down the potential issue and he let us know it wouldn't be wise to drive on the misfiring cylinder.

The car I have is not easy to find replacement parts even in Denver let alone for any shop in the mountains. I wanted to be able to help National Transmission by having the parts beforehand so I didn't waste their time and space by waiting for the parts once I got my car down there. Well... I was wrong and my car did take up their space and time for a week. They were very accommodating and even though I didn't set them up for success they were extremely helpful, fair priced and extremely friendly! Thank you to all!

Not knowing…read morethe area at all, I started calling around for mechanic shops we could tow it to and found this place on Google--figured we'd start there and see how it went. From the very beginning, they were upfront and honest, letting us know (especially with it being around the holidays) that they might not be able to look at the vehicle right away, which we completely understood. The very next day, they diagnosed the issue and took the time to call and clearly explain what was going on. They were incredibly communicative, kind, and fair throughout the entire process. In a stressful situation, they made us feel taken care of and confident we were in good hands. Go see them--they will absolutely take care of you.

After 3 hours' repair, they claimed the problem is solved. After we drove out of the store, it was only good for 1.5 hours and it is overheated again, thanks to their magical hands. We were stuck in the middle of nowhere and was towed again. They charged 865 bucks: 202 for the parts and 600 for the labor cost ($150/hour): I just don't know where the extra $63 comes from. Ryan actually worked 3 hours on my car, and said it is a 4-hours work. He explained how good he is and was able to finish the 4-hour work in 3 hours, and gave me a funny example of his 12 year old brother would use longer time and charge even more if mechanics are paid by actual working hours. I was just amazed how well he can debate; I think he should run for the president because the two candidates both suck at it. Hey Ryan, I think your 12 year old brother would do that better than you. Next time I want your brother to fix the car for me. Please visit this space if you want your car broken on the road again, being overcharged, and joining some really funny debate.

You will never see service like that at a typical auto repair shop and we can't thank Ken's Transmission enough for their excellent service and willingness to help us so quickly. To be safe they serviced our transmission and tested it to ensure no damage had been done after the repair to give us peace of mind. We give them an A++ score and can't recommend them more!
