I’ve been looking for a good diesel Mechanic for a while, a competent honest mechanic seems to be hard to find. I’ve finally found one. Chad and the guys over at M.M Diesel repair are awesome. I was prepared to pay over $6000.to repair problems I was having with my Duramax. Chad took a look at it and found that the problem was only a couple connector plugs. Very Honest and very competent, I love these guys I’ll take all my maintenance to these guys

Passing thru town, these guys were swamped, but they still were able to squeeze me in to help me get home WITHOUT taking advantage of me in a serious time of need. Extremely friendly guys and great mechanics, they even helped me realize a couple issues that I knew I needed to address, but their honesty about the issues really surprised me, little money now fixed by me or someone else will save me a huge bill later (unlike my home mechanic that installed the system for me, that told me to wait for the filters to fail).I have great respect for these guys, truth and honesty goes far, especially these days and in this bigger city. Thank you sooo much guys.

Took my truck to the dealership and they told me I needed to replace the entire turbo on my Ram 2500. I brought my truck over to these guys and they ran the diagnostic and found that the actuator on the turbo just needed to be calibrated. Saved me time and 💰. These guys are awesome. Thank you Chad!!!

Chad at M&M Diesel really stepped up and put everything aside to get my work truck up and running so my business can keep moving and I appreciate that. I would recommend them for anyone who needs their truck repaired.

Great work they got me in fast and all the enployees were kind and trustworthy i will definitely use them again.

Great local place for repair work. They are honest and fair when diagnosing my trucks problems. They work on both commercial and regular trucks. My initial problem wasnt with the engine, so they work on more than just engines. Had them install a lift pump and its been working great. Ill be going back when my truck needs work.

Chad was excellent to work with. I was stranded on the Wasatch Front and he worked me in very quickly and got me on my way. Reasonable price and great service. I have already recommend several family members to their shop and if I ever need service in the area I wont look anywhere else.

The guys are excellent and very knowledgeable. Will definitely be using in the future!

The best service and very honest people!!!!

Very honest! Great to work with, and so friendly. Definately use them again!

Great company, fast work, nice employees
