Diesel Transmission Repairs

"Hy-Tech Transmissions did an excellent job overhauling and upgrading my 2003 Dodge Ram 2500 Cummins Turbo Diesel stock transmission. Ryan Kuykendall at the Lusher Road, St. Louis MO location was able to work with my schedule and budget. I needed a quick turnaround on my daily driver so I didn’t miss time at work. By having a good long standing relationship with local and national part suppliers he was able to get what was needed. Ryan was also able to offer an upgraded triple disc torque converter and other tempting items such as a billeted input shaft. The upgraded torque converter has pushed my fuel mileage up 3 to 4 MPG as well as allowing my modified truck to put upwards of 1000ftlbs of torque at the rear wheels. He was even able to put a quick weld on a loose exhaust hanger. I had quotes at other businesses and Ryan had their prices beat without any add-ons.

This is a family owned business you can trust to fix your vehicle right. When I need another repair, Hy-Tech Transmissions will be my first call." - Rich
