“When my Cat 326F’s hydraulics stopped working, I was told the main hydraulic pump was out and that repairs would be costly and time-consuming. Fortunately, I contacted Pro Diagnostics. Due to their extensive experience with similar issues, they guided me through the troubleshooting process and shipped the necessary parts valued at $879. With just 7 hours of my own labor, I had my equipment up and running in just 2 days. Their expertise saved me money and minimized downtime. I highly recommend Pro Diagnostics for fast and reliable service.”

“I had a Mack truck with an automatic transmission that wouldn’t go into gear. I contacted Pro Diagnostics, and their mechanic diagnosed that I needed a new transmission controller. The dealer quoted me $6,800 for the part, but Pro Diagnostics shipped a pre-programmed, plug-and-play controller for only $3,700. I installed it myself, and my truck was back in service the very next day — no costly towing or dealer visits needed. Their support saved me thousands and kept my business moving.”

“My Volvo EC240CL wouldn’t start after I hooked it up for diagnostics. Pro Diagnostics shipped me an overnight test ECM, and after testing, we identified a bad ECM. The dealer quoted $5,900 plus drive time and labor, totaling over $3,800. Pro Diagnostics provided a programmed, ready-to-install ECM for just $3,900, shipped quickly and eliminating the need for costly service calls. Their prompt service and cost-effective solutions kept my downtime to a minimum. I highly trust and recommend Pro Diagnostics.”

 

 

“Custom Farmer in Indiana had built a manure pump using a generator with a C18 motor but was struggling to set the parameters for the motor to function properly. He reached out to Pro Diagnostics, and our extensive network of Caterpillar specialists was ready to help. We not only helped him identify and adjust the correct parameters, successfully getting his manure pump up and running—and making him money—but we also provided assistance for three of his John Deere tractor issues at the same time.

Thanks to our remote support and advanced technology, we were able to teach and guide his own mechanics without the need for a costly onsite visit from a dealer. This hands-on, cost-effective approach saved him thousands of dollars and empowered him to maintain and troubleshoot his equipment independently in the future.

 Pro Diagnostics has saved us over $32,000 in parts alone in less than four months. Their fast, accurate response helps us avoid unnecessary replacements—especially with the hard-to-find parts we deal with regularly. Pro Diagnostics were able to find the hard to get parts that the dealer no longer has.

They’re professional, responsive, and truly add value. We consider them a key partner at Xccelerate Construction.
