fluid being poured from a container

The transmission in your truck works harder than any other on the road. A fully loaded semi weighs about 40 times as much as a normal passenger vehicle, and racks up twice the mileage. As such, it’s essential to keep your transmission in good shape and regularly maintenanced. Fortunately, Harold's Used Auto Parts Inc in Philadelphia has you covered.

Automatic transmissions are becoming increasingly common in large commercial trucks. While the convenience of automatics is a revolutionary feature of modern trucks, these transmissions come with their own set of rules regarding upkeep. Regularly checking the fluid, inspecting the fluid, and changing the filter is the first and most important step in making sure your truck stays reliably on the road.

From fluid inspections to transmission flushes, our technicians do it all. We check for correct fluid levels and fluid conditions, looking for any signs of unusual wear or imminent failure. We also provide total system flushes, so you can rest easy knowing your fluid is fresh and ready to perform. Filter changes are another service we provide; since your transmission relies heavily on hydraulic pressure and freely accessible fluid, keeping your filter maintained is an easy and cost-effective way to make sure you’re getting the most out of your transmission.

No matter your truck repair or maintenance needs, our professional technicians have the equipment and knowledge necessary to get the job done. For the best fleet truck service shop in Philadelphia, call or stop by Harold's Used Auto Parts Inc today.
