Positive: Quality, Value
These guys are serious about getting you fixed and back out on the road. I rolled in with a Def problem and it took awhile but he stayed after it till he had it figured out, most shops would have given up but not here...
Good price, Good people, killer stock of parts....
Service: Check engine light diagnostic

Truck had a steer tire blow in Spencer, SD (roughly 20 miles east of Mitchell, SD from where their shop is). A & G Diesel gave great customer service over the phone to both the company and the driver to find the right fit to replace the tire. The service truck arrived on site in less than an hour and then got us on the road quickly. We greatly appreciate their services and the great deal on tires! Thank you again!

Called 30 minutes out with a possible plugged fuel filter due to cold weather and me not buying #1 diesel. Mike answered the phone and after a very brief conversation he said bring it in. Although he had a full shop and trucks in the lot, he dropped everything had my fuel filter ready. In conversation he told me exactly where I had gotten fuel (it had not come up in our pryor conversation) and that I was not gelled up. It was that the fuel at the truck stop was in elevated tanks and it was just to cold. None the less a fuel filter is cheap and he had me running in 15 minutes. Mike is your guy,

Absolutely the best! I broke down just outside of town Mike came out and it couldn't be fixed on the freeway. He got me a tow and after i got back to his shop it was after hours he amd another technician stayed and diagnosed the issue and by noon the next day i was up and running. If you're in the area and need service i highly recommend.

The crew at A&G are great!!! I can't say enough good things about these people. I broke down on I-90 in my Semi. The road side repairman got me going enough to get to their shop, where they were able to fix me enough to make my delivery in Kendall, S.D. I forgot to mention that the weather was miserable. 9° and a fierce wind. The price was very reasonable . Thanks for your help.

I broke down in Mitchell SD.
I called A&G Diesel Repair Mike as busy as they were sent over Matt and spent time trying to see what was wrong at the end of the day A&G could of took the easy way out and sell me a turbo but as it turns out Matt said I only needed the Turbo auculater a big cost savings.
Matt went the extra mile and came in on his day off and got me going.
Great shop and people

I am a musician and I own a Diesel Shops worst nightmare an old converted bus with a 6V92T Detroit Diesel engine. I know from years of being around busses that they’re never anyone’s favorite thing to work on. A&G Replaced the brake can, aligned it, fixed the u-joints, and a full service, and I was amazed at how inexpensive the bill was. Not to mention the fast and courteous service. I would strongly recommend anyone will the “BIG RIG” consider having their vehicle worked on at A&G and A&G II!

Be careful with these guys - can I say CROOKS!
We had a truck that blew a hose clamp on a radiator hose and lost antifreeze. Super easy fix - I even sent a picture of the broken hose clamp to fix - no diagnostics needed. Replace the hose clamp and put antifreeze in the truck. Easy enough job. COST $453! ARE YOU KIDDING ME! $60 in parts but the bill is $453! I call CROOOOOOOK! Called to complain and they say it took 2.5 hours to fix - no it didn't! I had the bill via a text message 35 minutes after I sent the picture of the broken hose clamp to the mechanic.
I warn - BE CAREFUL WITH THESE
