" Back in January they did an amazing job diagnosing my truck, a section of the fuel lines collapsed. Purchased a Fass lift pump a few weeks back from them. Just purchased a work series transmission from them last week. Overall their products are great, served with amazing customer service. There aren’t many companies that offer both great products and service, and a company with a personality i never feel like im taking to a robot. They’re a company I’m happy to give business too. "

" Eric and his team were awesome. I had a failed injector pigtail and I limped my truck into their parking lot at 4 pm. They helped me get back on the road to arkansas and were super dedicated to making sure my L5P ran right when we left out of there. Customer service was above and beyond genuine. They had everything I needed in stock. Location is in a good spot and easy to find. They carry Schaeffer oil products, and were actually cheaper than ordering it online. Awesome dudes with a stellar and famous product line. "

" Late on the post/review amazing business and employees. I walked in to see if they had parts for my truck for my needed new fuel lines and new gaskets for my Y bridge. They had the parts and for a great price! I was able to get my new fuel lines and my upgraded part in also. now my first diesel/Duramax running good! Definitely going back if I need it worked on or need parts from them in the future! "

" I had a great experience with Merchant Automotive. I brought my 2019 Duramax in after two different shops told me I needed a complete transmission replacement on my Allison. Before spending thousands on a new transmission, I decided to get one more opinion and took it to Merchant Automotive, 3 hours away. Their team took the time to properly diagnose the problem instead of just recommending the most expensive option. They found the real issue (Wiring) and were able to repair it instead of replacing it, which saved me a huge amount of money. You can tell these guys truly specialize in Duramax and Allison trucks. They were knowledgeable, straightforward, and communicated clearly throughout the process. The truck now shifts perfectly and drives like it should. It’s hard to find shops that are this honest and actually troubleshoot the problem instead of throwing parts at it. If you have a Duramax and need transmission or diesel work, I highly recommend Merchant Automotive. They definitely earned my business. "
