The PCM (Powertrain Control Module) is the main computer unit that controls your engine, as well as the transmission for automatics. In general, these are well-built components that should last hundreds of thousands of miles. However, there may be instances where a driver needs a 7.3. PCM replacement, and we’re your best source. Our 7.3 Powerstroke PCM replacements may be either rebuilt units, or good (fully tested) used units. When we buy cores from wholesalers, some of them are perfectly good working units. These are sold with the same warranty as our rebuilt units. The main cause of PCM failure continues to be people pulling out their chips with the key on / engine running, which almost always fries the microprocessor and the chip. In many cases, the reason they pull their chips is because their trucks are performing strangely, which may be caused by something as simple as dirty chip terminals. Occasionally it's the EEPROM that can fail. Our 7.3 PCM replacements are backed by a 3 Year Unlimited mileage warranty!
