At Harold's Used Auto Parts Inc in Philadelphia, PA, we have the facilities, equipment, and technicians necessary to complete any job, no matter how big or small. When it comes to fleet and diesel trucks, the right people with the correct equipment makes all the difference - we’ll keep your truck reliably on the road, and we’re the fastest, most efficient repair facility in the business. When it comes to trucks this size, and this valuable, cut-rate maintenance and repair simply won’t do; you need professionals, with the tools and equipment necessary to get the job done right.

While transmission flushes are just one of the countless services we provide, it’s an extremely important one. On fleet trucks, the transmissions work hard, hauling heavy loads over long distances, day in and day out. Over time, the fluid in these transmissions breaks down, leaks, or becomes contaminated, and a transmission flush is necessary to ensure your truck keeps shifting and pulling as it should.

A transmission flush is more than a simple fluid change. We run fresh fluid through the entire transmission, pushing all the old fluid out, and drawing new fluid in - this not only ensures that all the fluid in the transmission is fresh, but it forces out any build-up, sediment, and grime that has accumulated anywhere in the transmission. Transmission flushes should be done at regular intervals, or anytime one is necessary in between. If you aren’t sure if a transmission flush is necessary, come see us - our technicians can inspect your truck and determine what course of action is required.

No matter your repair or maintenance needs, our professionals have you covered. From transmission flushes and oil changes to tire replacements and engine rebuilds, for the auto service shop in Philadelphia, PA, call or stop by Harold's Used Auto Parts Inc today.
