If you have transmission issues going on, we work on those too!! This 3.5 ecoboost f150 with the 6r80 transmission was having intermittent no start issues and not coming out of park, which these are notorious for the lead frame (conductor plate) on the transmission valve body to go out and cause these issues and set a bunch of codes. Removed the valve body from the transmission and replaced the lead frame and got this one back on the road! Call me if you are needing auto/diesel repairs 615-796-1409 📲

If you have issues with your 6.0 powerstroke give us a call! This one was running rough with cylinder #3 and #4 contribution codes, overfueling trying to hydro lock the engine and failed injector buzz test. Going back together with a whole new set of 8 injectors and pulled the turbo to “fix” the EGR cooler issues. Give us a call 615-796-1409

If you have extended warranties on your vehicle, we work with those too!! One of our good customers is in the shop for a 100k mile service- tune up, replace all the fluids and replace front brakes! It is a requirement in your service contract with most warranty companies that you do this to be able to keep your extended warranty valid if you bought one with your newer vehicle and also it helps to keep your expensive powertrain components to last longer, maintenance is always way cheaper than replacing parts in the long run!! Call to get on the schedule 📲615-796-1409
