Increasingly, technology in automobiles is becoming more sophisticated, and more and more systems have become reliant on electronic control modules to operate. At Harold's Used Auto Parts Inc in Philadelphia, PA, we have the trained technicians and the equipment necessary to deal with issues that arise as a result of these components.

Your ECU monitors and directs nearly ever sensor, module, or electronically controlled system in your car, truck, or SUV. While the ECU itself is a generally reliable component, sometimes bugs and problems come up that result from small problems within your vehicle’s programming. Your transmission is no exception - a transmission that acts erratically, illuminates warning lamps on your dashboard, and can’t seem to be diagnosed, may have TCM or ECU issues that need to be addressed. To the trained professional, an ECU issue is a problem that can be fairly easily rectified. By knowing what to look for and with the right equipment, an ECU can be reprogrammed or adjusted to get rid of issues like constant sensor malfunctions, anti-theft system issues, shifting malfunctions, and a variety of other problems - having your car, truck, or SUV shifting like new in no time. No matter your repair or maintenance needs, we’ve got you covered. For the best transmission service shop in Philadelphia, PA, call or stop by Harold's Used Auto Parts Inc today.
