Slate Cut Diesel and Auto in
Crested Butte (CO)

Our 15 passenger bus broke down after coming down Cottonwood Pass, off Jacks Cabin. With 8 kiddos in the car and a flight to catch the next morning, Galand kindly took a quick peek at the car, topped up our power steering and provided sound diagnostics/advice, despite being totally booked out for weeks - and refused a $tip. VERY grateful!

Trustworthy and timely service. Two important traits needed in the stressful situation we faced while on a trip with my Ram 3500 tow vehicle in June, 2025. We had a radiator hose and connector tube burst. Galand repaired the truck quickly and in a professional manner. I trusted him so much, I requested that he replace the serpentine belt also. I trust him still to this day and "NO" I am not related to Galand. Never met him prior to my road trip problems. Lance Kreuger at Kreuger Tires in Gunnison, CO refers his diesel truck owners to Galand for repair services!! Gratefully, Scott Haanstad

I can't recommend Galand and Slate Cut enough. Our brakes went out on our 4Runner while visiting Crested Butte, a very scary situation. Galand was able to get us in same day and back up and running the next even with being booked out until August. Fantastic work from a Colorado lifer familiar with the area's challenging mountain roads. Not to mention he's a straight up great guy! 5+ stars

Helpful, honest, fair and knowledgeable. Will absolutely continue to bring my truck here. Highly recommended!!

Galan is amazing. His customer service and hospitality is hands down the best I’ve ever had. He’s the type of mechanic that you hope to find in your area. He’s isn’t trying to take advantage of your situation and makes sure to get you back on the road as quickly as possible. I wish there were more people like him.

Galen is the absolute best! Knowledgeable and professional, friendly and does the thorough job that not many will. Definitely happy to have come to slate cut!

I never thought I would want to write a review about getting my oil changed, BUT Galand, the owner was so helpful. He helped me catch a ride on the bus, he gave me a personal demonstration on how to navigate mountain roads so I don’t ruin my brakes. I will always call him first for my car repairs. Thank you Galand for being an assetto this community, my home away from home.

Galand is the most knowledgeable diesel mechanic I have ever met. When is was traveling from out of town I was having issues with my Chevy Duramax. I pulled into his garage location, he was extremely busy working on someone else’s truck. I talked to him fo a few minutes about my issues, told him the error codes I was getting and to my surprise dropped everything he was doing and said let’s go look at your MAP sensor. Sure enough it was semi clogged with soot. He checked a couple other things then told me what was needed, pulled my truck into his shop and worked over an hour on things and now my truck runs like a new vehicle. I would highly recommend Galand for any issues or work you need on any diesel or gas vehicle out there.

Galand/Slate Cut was among best service I’ve ever received. Called him on a Friday with an inoperative Ram 3500. He ordered parts and had me running by Monday. If other auto service was half as good as Slate Cut…. Thank you Galand

Galand is super knowledgeable and wonderful to work. We have had our car with him many times and we highly recommend his body shop!

I recently popped a tire on a mountain pass in crested butte, and after being turned away by many busy or closing auto shops I called this mechanic. He told me to come right then, and he not only took a look at my tire for me (unfortunately too far gone) but he also offered to add air to my donut tire, adjust 4WD settings for the meantime, and gave me loads of helpful advice and support in getting home to Colorado Springs. This mechanic is not only intelligent and capable, but kind and compassionate.

Gaylamd is by far the most experienced mechanic when it comes to diesel by far. He diagnosed my ram 3500 in seconds and all though my turbo was shot he gave me the straight up truth. He's very honest and knows what he's talking about

Galand was fantastic and very kind. We thought something was up with our break or wheel bearing and he was able to look at our civic on very short notice. He gave us piece of mind, and even dropped us off and picked us up from the bus stop so we wouldn't have to walk along Hwy 135 and potentially get hit!

Galand was a dream to work with even though we had a nightmare situation. We were stranded in Crested Butte, hundred of miles from home. He was able to get us back on the road in a reasonable timeframe. He always was available to give us updates on the repairs.

Galand got us in with no trouble unlike the Dodge dealer. It was a trip emergency and he got us back on the road. Very fair in his charging for the work done again unlike the dealer. He explained everything. Thank you!

Galand helped us out with our Sprinter van that wouldn't start due to excessively cold temps. He showed up in 10 minutes and got us started! We had some engine light issues and he helped with that, as well. He was fast, friendly and totally helpful! Thank you Galand!

Once again Galand saves the day! our truck was in limp mode, MAX 5 mph speed, due to Def issue and he fixed it! If you own a Dodge you better get to know Galand! He is the best!

While hunting in the area up from Central Texas my front end on my Dodge 3500 blew up. No body in the area would even look at it for two weeks. Slate Cut took it in and started repairs before any one else would have seen it. They did a fast and great job. I highly recommend them

Me and some buddies got in a bind in crested butte with a blown radiator and made a phone call to Slate. From the first phone call to the very last, we were treated with the utmost respect a man can give. Slate is an all around great business and I highly recommend everyone use them for the mechanic needs. Great price and did a great job on my truck.

My fiancé and I were broke down on our vacation from hell, Galan went above and beyond to help us out and get us back on the road. He is a very knowledgeable diesel technician and does the job right. I would highly recommend him if you are in the area and need a qualified technician to take (or tow) your truck to. He’s a stand-up human being in general and can be trusted to do repairs on your truck. I wish there were more people like him in the world. Thank you Galan !!! You r done a fantastic job on my truck and you have done a fantastic job of restoring my faith in humans.

I am vacationing in Gunnison with my family. My truck had a diesel exhaust fault. Tried every business in Gunnison with none willing to help for weeks out. Even with the explanation of not being able to leave until repaired. We found Slate Cut Diesel who was friendly, professional and knowledgeable of what was going on with my truck. He understood I was stranded without any help. He fixed my truck within an hr of me arriving and without him our vacation would have been a disaster. People like Gaylan is what makes small businesses my go to for support. Thank you so much!

Kindness and professionalism blew me away. My van(home for the week) had a bad coolant leak. He put a rush on the job and was able to get it done the same day! Not to mention dropping me off back in Crested Butte and picking me up when it was finished. And the price....he really had a chance to exploit my situation but did nothing of the sort. It really was a great experience!

I am extremely happy and grateful with Slate Cut and its owner Galand Niccoli. I was in a bind late Thu, and I called Galand at Slate Cut. My wife and I were only staying in town until Sat, and my brake pads had worn out completely on our trip from out of state. Galand was extremely professional, got me back on the road on the next day, and even provided transportation to and from Crested Butte. Its a month later, I am just getting around to a review, and the brakes are working like new.

Gayland was a joy to work with. He was knowledgeable, professional, quick and trustworthy - 4 qualities that are so important when you stranded 14 hours from home. Gayland diagnosed the issue quickly and had the part the next day. The free transport back to town was the icing. Highly recommended.

We are up from Dallas. I had an issue with my air bags. Galand got it working with spare parts so the bags would hold air so I could pull the trailer home from Almont. No charge. I felt bad as I has like $13 cash and he wouldn’t run anything on a card. Can’t say enough about the guy. We are here each year for two weeks. I’ll be back next year and will have a nice surprise for him.

I recently had a head gasket failure on my Duramax while vacationing in Gunnison. Fortunately for me I also meet Galand Niccoli while on my trip. He was awesome through the whole experience and did a great job diagnosing the issue and giving me some real numbers right away. I ended up having to replace my engine and Galand had zero hesitation about taking on this huge job. I was also amazed at all of the extra things that he did for me at no charge. Me and my truck couldn't be more pleased with the results. Do yourself a big favor and go see Galand before wasting your time elsewhere.

Drove 16 hours from home to CB and the next morning my brakes were horrible. The first shop I went to in town were unable to fix them until 3 days later and they were very unclear about pricing etc so I called around to every shop in town and found only Galand (at slate cut diesel) to be very helpful over the phone. I brought my car in and he checked all my brakes again and found they all needed to be replaced. He showed me how bad my brakes were and he was able to get the parts that day. He even gave me a ride back to my Airbnb because the taxi I was using was very expensive; during the drive he explained how to use manual in my car so I wouldn’t mess up the brakes again on the mountain roads. He ran into an issue where one of my brake parts rusted so badly and no shops nearby sold the parts. He went above and beyond and drove to Colorado Springs (a 3+ hour drive) to get them and finished the car the next day. Best car mechanic I’ve ever used and just a great person! No surprises when it came time to pay and he was very upfront and fair. Wish he lived in my home town. Fully trusted him to care for my car and he explained everything so I knew what was going on.
