Luis is extremely knowledgeable. Ive been taking my truck to him for over 8 years now. He really is the best. If he can find a deal for me, he lets me know. He literally saved my truck from a total rebuilt transmission. Not only has he saved me money over time, i will continue to give his family my business because he is honest, fair, hard working, and shoots straight from the hip. If you need some serious work done, Luis is the man to see. In my opinion, hands down, best gear head in SA!

Wont recommend at all this work place for your vehicles ... First of all the owner luis dont answer the calls and if he does he answer in a aggressive way .. MY truck Was sitting there for nearly 2months with out nothing been done Friday he says it was gonna get worked on after 2months Monday he says its ready and Tuesday they call and say its stolen after 2 months sitting there ...they dont want to be responsible for the truck being stolen.. a friend of my took it for transmission work and didnt fix it at all either ... NOT A RESPONSIBLE SHOP AT ALL....

Very good shop! Luis estimates prices very fair with vary trustful work and experience! I took my Cummins in for some work and he did excellent and had my truck fixed within the time estimate he gave me! Front desk was very friendly and Luis gave me updates weekly on my truck! Highly recommend if you want a fair trustworthy job you won’t regret it!

As a woman I am always hesitant to go into a shop because they always try to sell me things I don’t need so it was such a great experience when I took my truck and and Luis told me exactly what I needed. He was very professional and got my work truck running in no time. He has definitely gained a loyal customer.

Luis is a very knowledge mechanic. Fair priced and didn’t tell me I needed stuff that i didn’t. Fast work and very reliable.

Very great service and great prices. Knowledgeable staff and owner of the place. I only take my f350 7.3 to this place.I recommend them to anyone and everyone with a diesel.

Three Brothers Diesel has always taken care of all my work! Best all around town!! Luis is a very Trusted mechanic.

Honest man does a great job, did my truck and never had problems with it, I recommend this guy and his work

I took my 3500 ram diesel, excellent work professional 👏 plus luis wont let you take your truck unless hes happy with what its been done he goes the extra mile to make hes customers happy and always a fair price.

Don’t recommend!!! Don’t waste your money!!! Never answers the phone and when they do the owner answers and gets mad !!! Bad work & Bad service!!

Very bad service, dont waste your time and money, and potentially your truck here. DO NOT GIVE THESE PEOPLE YOUR MONEY.

Great mechanic, always very trusted and does great diesel work!

Worse customer service and their work was equally horrible never going back here again. If I could give 0 I would.

They had my truck for 3 months and they never answered the phone until they called us telling us they strolled the truck. I don’t recommend it don’t go to them!!!

Bought a truck at Auction that needed a new short block. Im from out of state and read reviews to find the right mechanic. Luis and his crew are top notch. Installed a new short block in my 6.4 and I drove 1300 miles straight from the shop. I would highly recommend for any Diesel truck needs! Cant beat the rate they charged and the quality of work.

Great shop for diesel or gasAlways take my trucks thereFive star customer service

It was great! Fixed my truck really goodAnd Im very picky! Was very satisfied

Very bad job i took my truck for an electrical fix and they changed the catalysts and they didnt tell me to change them i just realized and they still did a bad job bad welding air leaks everywhere when they take their car to this workshop check catalysts that are all your parts of your car because they are changed.

I don’t recommend this shop Bussine they stolen the truck and they don’t responsibility

I couldnt have landed in better hands. Luis is very professional and a very very honest about his job. I wouldnt twice about recommending him and the shop. There are very few people like him nowadays! Thank you!

Im from out of town and needed a quick turnaround on a Fass Fuel System. The owner did just that. He took the time to explain his process and what all was going on with the truck. If you can find a better price somewhere else youre probably taking a big risk. If youre ever in San Antonio and need an honest, reliable, diesel mechanic Three Brothers is your solution.

This team was a delight to work with!

I took My truck F250 which did not want to start they immediately worked on it Even though there was no rush they were very respectful and they really do know what theyre doing And prices are very very reasonable I also asked about some other issues and they explained to me What it could be so I could try to do it myself without even charging Me

Very knowledgeable on what they do, took my 6.0 diesel in the morning and had it back at home that same day. Highly recommend giving them a shot I will be going to them from here on out, it’s hard to find a honest mechanic now at days.

Very impressed with every job thats been done to all my vehicles Louie knows what hes doing..HIGHLY RECOMMEND 👍

Very knowledgeable staff and team. They sure know what they are doing and talking about

Bad work don’t recommend

My truck broke down they where very nice and helped me fix it in an hour

I went there because of the Google reviews and they were right. They quoted a fair price, stuck to the quote, did quality work, and backed it up. This is my diesel repair shop now.

Luis is A Very Knowledgeable and Hard Worker!! Together he is Fast and Reliable! I used him to get my Big Truck back on the Road. He is mobile if u need him. Car, Truck, or Big Rig. Luis can Handle it. I joked with him about helping him get a big shop and Start a New Company in San Antonios Region. Dont be Surprised if we did.. He could handle it with the right staff.. Call him with Any Issues!! He will do u right!! Thanks Luis for helping me and Stay Humble, Ur Time will Come!!

Took my lifted 2012 f250 to get A diagnose to why a vibration was coming from front of my truck. Turned out it was my wheel hub . Luis diagnosed it quickly and got my truck done quick and right ! Definitely earned my business And prices are right ! Luis knows his stuff thanks again brotha

Good place and it is cheap and it is very fast The work is done very well and they are all good people I all recommend them.

The best diesel mechanic in SA TX, its a bold statement but we run ambulances non stop and have to trust our mechanic unconditionally. He was available at all hours and often traveled to fix our units on the spot! I highly recommend this company!

My cousin had his duramax diesel rv, decide not to start, and strand him. I tried installing a new fuel filter in a parking lot, but I am not a expert like Luis and I did not bleed it right. We called on Luis and he came out and bled the system and it worked fine. Luis waved the service charge saying it was nothing, I am never seen such a thing in my life. These guys know their stuff and I am so impressed by the integrity, that is why I am writing this review! Totally impressed!!!!!!

Best preformance shop on the south Guaranteed to get you on the road again

Good work at a fair price 👍

Followed these guys because they do excellent work on our ambulances!!!!!!

Our truck has been a real challenge

Luis is an excellent person and a very good, very professional mechanic, I always take my cars there and I have never had any problems.

Worst job. Not good service. Very ugly employees
