These men treated my daily driver 1993 1st Gen Cummins like absolute PROS! My baby and I have been together since 1996 and when it was time for a new transmission, they put in a beauty at a fair price and well done. They know what they are doing and are nice people... read more

Allegiance Diesel - Vincent is the man! - Auto Repair Near Me - Gardnerville, Nevada

After recommending this place to a friend, he is close to $30000 into his truck and now has a truck that does not run. After the original owner sold the business to his lead mechanic. They are refusing to warranty the work and saying the repairs will cost over 20000 now. read more

I really recommend this shop... You can safely defer to Anthony and Vincent on judgement calls and trust that their skills and craftsmanship are best-practice/ race/ performance tier--these guys run a tight ship, you don't have to worry about some sloppy tech getting it wrong. Allegiance is extremely competent and careful while also being fast and reasonably priced. They make time to explain options and are patient with questions. Northern Nevada is truly lucky to have this shop. read more

Tony, Sterling and Vincent are all amazing mechanics with the highest of integrity. I have trusted them with all of our vehicles whether diesel or gas powered for years. Tony is especially good at repairs on older makes / models too such as our 78 FJ40. This is the place to take your vehicle for repairs. Compared to dealer prices and others in the area, they provide very competitive quotes and provide good value for what they're charging to repair your ride. Of looking for trustworthy mechanics, look no further. You've found them...! read more

Anthony and Vincent went way out of their way to help me out. I didn't want to drive my truck due to a check engine light that came on so I stopped by their shop on a weekend and explained my situation. They ended following to the house (where my truck was) and checked the codes for me. They instantly had diagnosed the problem and got me on the schedule for a repair. They charged me a fair price and got the work done quickly. I highly recommend this shop. Honest, friendly people! read more

Had them work on my Chevy Duramax many times, always did a good honest job. Had new turbo, injectors and up pipe behind engine installed. They also fixed my leaking leaking egr system. Also had them diagnose my wife's VW Jetta. read more

Natasha and Anthony are the best! Have always taken care of me! Back when they ran "All American auto." And now as "Allegiance Diesel" they are the best of the best! Always helped me with my old 97' 7.3 powerstroke. And now with my Brides suburban! They fix it right using quality parts and not cheap replacements where you'll need to be back in a few months for the same issue. I always use them and hope they get the best business in the valley! read more

See all

Didn't have any work done there but they didn't hesitate to answer my questions and get me going in the right direction so I could correct the issues I was having on my truck had I had the money to pay to get the repairs done I would have definitely had them take care of it knowledgeable and understood what I was up against and got me going with what repairs I needed to do to my truck so I didn't just end up throwing parts at it read more

My 2019 Chevy 2500 Duramax has been a total money pit from continuously breaking down. The warranty hasn't covered nearly any of the costs from the many trips into the GM dealerships to get repairs done. My latest breakdown was due to a bad transmission cooler and after making an appointment at a local GM dealership in the hopes the fix would be covered by the warranty which it wasn't. I was told the part was ordered and I would have my truck back within a week. After 7 days, I received a call from my service writer saying the dealership couldn't track down the part and had no timetable for when my truck would be fixed. I called Allegiance Diesel and spoke with Tasha and she was so helpful, friendly and got the part ordered and scheduled me for the repair within a few minutes. My truck was fixed within a couple hours of dropping it off and the cost was literally half of what I was quoted from the dealership. Anthony and Vincent took care of the repair and couldn't have done a better job. Allegiance Diesel did an amazing job in a few hours what a dealership couldn't even find a solution to in over a week. From regular maintenance, upgrades, or breakdowns with your diesel do yourself a favor and Call Allegiance Diesel in Gardnerville. I will never take my truck anywhere else. Thanks again to Tasha, Anthony, and Vincent You guys are AWESOME read more

My son took his diesel to here after being quoted 4500$ more to fix it to add to the 4500$ bill he already had with them. We were quoted 2000$ to fix it. It has run like a champ since. They even did it a week earlier than they said! Top notch service and friendly and knowledgeable staff. read more

Anthony at Alligiance Diesel gave excellent advice and repair to my 2013 Ram 2500 was top notch.

Excellent service and communication. Would highly recommend this shop if you need some work done on your truck. Anthony and Tasha kept me up to date on my service and the price was very fair. Would highly recommend. read more

It's really hard to find a business that is honest an isn't trying to make a killing on ever service, but is more into making relationships then anything. Anthony has a lot of integrity. I've been going to him since 2018 and will recommend him to anyone. read more

Great place! Stopped in to get some work done on my vehicles and I was treated kindly and professionally. Staff is friendly and organized. All around great bunch of people. read more

These guys were such a pleasure to work with. I brought my Duramax to another shop and got a ridiculously high quote, I called around to a few different shops and then talked to Tasha, who was super knowledgeable and familiar with all the work that needed to be done, and got me an accurate quote right away. This was a huge job, $10k worth, so it was great getting an accurate quote and not a bunch of add ons at the end. Highly recommend these guys. read more

We were extremely impressed with the service we received from Allegiance Diesel! We don't have a diesel vehicle, but we have a gas powered RV that would not start. We were thinking the fuel pump needed replacing and dreading the thought of that costly repair. But after a quick computer diagnosis, we learned the RV had just been sitting a bit too long without being started, and the fuel pump needed to be primed. It took just a few minutes, and the engine started right up! We are so grateful for the owner's prompt service and honesty. Apparently, he is a great gas engine mechanic, too! We will definitely be returning when we need additional service on our RV, and we highly recommend this business for their friendly and honest service! read more
