This shop performed a transmission service on my F150. The first time it was on a long trip while towing, the transmission failed and sprayed fluid all over my truck and trailer. The tech at the dealership I was towed to said the transmission, even after losing all that fluid, was still over full and bolts were not tightened correctly. The owner, Todd, denied all responsibility. I wasn't going to leave a review until speaking with him, now I don't think anyone should trust their truck to these guys. read more

My partner and I had our truck's transmission rebuilt at High Country Transmission in Denver. The same issue came back a few weeks later, and the shop claimed to have rebuilt it again under warranty but couldn't provide any documentation of that work. We're now 1,200 miles away with the same problem and a refusal from the shop to right their mistake. Very disappointed in the lack of transparency or accountability read more

I brought my truck to High Country Transmission in Denver for a full transmission rebuild, a job that cost $4,000 and was supposed to fix a delayed engagement/slip. Instead, the exact same issue returned within a few thousand miles. I brought it back, and they claimed to have "rebuilt" it again, but now, 3 weeks later, the problem is back yet again. The same problem I took it in for initially. What's worse is that they kept no written record or documentation of the second rebuild, won't provide any service details, and are now refusing to authorize warranty work at another certified shop, even though I physically can't bring the truck back to Denver (now stranded in Idaho). Per Todd, the owner when I requested service records on 10/7/25: Per initial build "You should have kept the original receipts" Per warranty rebuild " I do a lot of rebuilds I don't have any records for it" Not only was the original problem never fixed- Todd refused to even provide records of what he did do. This is the definition of poor workmanship and zero accountability. Avoid this place at all costs. The lack of transparency or record keeping speaks volumes about how they operate read more

I've been wanting to do this for a year and a half, but both my wife and I have had significant health problems as well as mechanical problems. The advantage to the reader is the report of the quality of workmanship and care over time. We don't have internet, so we had to ask someone to help us with this. My '99 van and I are old and rusty, but it's still better-looking. Since I'm in a chair, my van is not just my transportation, it's my legs. It's how I make Drs. appointments as well as daily life necessities. There are places and times unreachable by bus. The last time my van went down, it took 4 emergency vehicles and 7 police and firefighters to get my 250-300 pound chair in one vehicle, and a heavier me in another, just to get home. I was stuck. Getting around without my van is a nightmare. Dependable transportation for me is crucial. Replacing the van itself would have been cheaper than the repairs I've done to it. However, lifts and their installation are extraordinarily and unreasonably expensive, and they won't install one in a van that's over 3 years old. (New vans with a lift cost $100 grand.) We live on a very limited fixed income, and can't afford much of anything. If it wasn't for some friends, we would not have been able to afford the transmission. I had to deal with everything by phone. The owner was so polite, helpful, and considerate, and assisted wherever he could. The transmission needed to be completely rebuilt. It was completed in a short period of time after it was received. The transmission has performed perfectly and with no leaks since we got it back. It shifts smoothly, properly, and timely. It has been the epitome of dependability. Although I am not one to stress a transmission, it seems powerful enough to do any job. Conversations over the phone were always pleasant, helpful, and honest. He even arranged to return the vehicle to us, even though we are some distance from him. He did all this for less than estimates from a number of others, including chains and multiple-location shops. With both of us being disabled, that was so helpful. If you are disabled, or a vet, or anyone else, you might want to take a look at these guys. JACK read more

These people care. Russ was great. They did a wonderful job and communication was good. I trust them and that says a lot.

Way more than was quoted. I would have paid less for a new transmission and had another shop install it.

Totally professional and help fully diagnose the problem I was having after the transmission rebuilt for my race car. Fully stood behind their work and opened the transmission back up during the diagnosing period fully ruling out any problems with the transmission. Problem was throttle by wire issue that was caused by multiple wiring issues to the ECU that through transmission codes. Back on the track racing. read more

Real down to earth here at this shop. Called 5 different transmission shops and this location bested others pricing by 8 hundred all the way up to 2 grand! It pays to shop around. You can tell Todd and Larry have been doing transmissions for a long time. Dropped my truck off on Tuesday was told it would be ready Friday morning and it was. Straight forward service with a year warranty. Reminds me of small town service. Definitely would recommend and hopefully I won't need their services anytime in the future but if I did I'd drive (or have towed) my vehicle across the state to use this HONEST shop again. read more

I cannot say enough good things about High Country Transmissions. I have two late model Ford E-350s and one of them needed a rebuilt transmission. While rebuilding a transmission isn't really a joy, I had a great experience the business and the owners Todd and Larry. My particular vehicle had some issues after the transmission was rebuilt, but they took care of the issues at no charge and assured me they would stand behind their work, which they have absolutely done. High Country Transmission was recommended to me by my mechanic and I would recommend High Country to anyone who is needs to have their transmission serviced, rebuilt, or replaced. I am a lifelong customer of theirs because they are honest, nice, and knowledgeable about all things related to transmissions. read more

Recently the transmission on my nephews 2000 Camry failed. After calling several mechanics all recommended High Country Transmission as being the best and the only place for the repair. Spoke with Todd and Larry at HCT who agreed the transmission needed to be rebuilt if we wanted to keep the car. The cost was reasonable and the work was completed in less than 2 weeks. My nephew said the car has never ran better. I highly recommend HCT, they are very professional, welcoming, and ran a clean shop. read more

These guys have been fixing and maintaining my transmissions for years, my son had a transmission rebuilt by them and they replaced my son's new transmission for free even after it was out of warranty. Excellent service, my son killed his transmission by slamming it into gear and down shifting hard on an automatic transmission, it was his grandmother's old car. read more

The guys at High Country are fantastic! They are honest and knowledgeable and kind. I was having trouble with my Ford Explorer and feared it might be the transmission. I took it to an automotive repair business to have it checked out and they referred me to High Country. High Country checked it out and drove it and concluded that the problem was not the transmission but probably needed a reset on the computer. Now I have an appointment with a Ford dealer to take care of that and I hope to have as great of an experience there as I had at High Country. 100% recommend this business for all your transmission repairs/replacements! read more

If you're having transmission issues and live in the Denver area this is the place... What an incredible staff of individuals. Kind, professional, fair.. something you're not likely to find at every shop. I'm from Atlanta and broke down there unexpectedly and they had my truck up and running in a less then weeks time. read more

The owners/workers are honest and reliable. USE THIS SHOP! They looked at my car after I had it towed there and provided a thorough assessment. I can't speak highly enough about this shop and these guys. VERY easy to communicate with. read more

friendly service. Reliable and excellent work. I bought a rebuilt transmission for my dads hot rod model t and I have to say it was worth every penny!!!

Great guys. Honest and straightforward. Had to get my transmission rebuilt on my Dodge Cummins. Larry told me exactly what was wrong, repaired it with no issue and was done exactly when he said he would be. Went to pick it up and the Todd and Larry took the time to invite me back into the shop and explain the repair. I will go here for all transmission related repairs from now on. This kind of service is hard to come by anymore. read more

Just had my transmission in my Subaru replaced . Professional and honest folks, first class quality job . Car drives like new again.

This shop went above and beyond to get me back on the road quickly and for less money then I could have ever hoped for. Bring your vehicle here and you won't be disappointed. Thank you so much guys! read more

Excellent service! Owner Todd helped me get back running on my way through Denver, and was friendly beyond comparison to other shops. Immediately he diagnosed a minor transmission problem which was apparently a quick and easy fix. Didn't seem over eager to give me bad news (read: sell the big $ job), and it would appear his guys fixed the problem. Thanks Todd, and good recommendation of the cafe down the street! read more

This is a great place for transmission service. The long-time owners are professional in every way and above all they provide honest service. I recommend them highly. read more

High Country Transmission is by far and away the best auto shop I have ever been to! I took My GMC Terrain to another mechanic because it was making a terrible grinding noise, they ended up giving me an incorrect diagnosis so I was going to be without a car even longer. I called HCT and they said they could get the car in the same day to diagnose the problem and wouldn't charge me for it. They called me the next day to let me know the transfer case had gone out, which is a very expensive repair. I called around to get prices at other auto shops and HCT was hundreds of dollars less than anywhere else. They have been more than helpful in getting my car fixed and I cant thank them enough. I will without a doubt be taking my car (and future cars) to them for repairs from now on. read more
