Detroit Diesel for Sale

Detroit Diesel ECM, PCM, and TCM Modules

When it comes to hardworking diesel engines, few names carry as much weight, heritage, or instant recognition as Detroit Diesels. Known for power, reliability, and longevity, and an immense legacy of both 2 as well as 4 stroke diesel engines, Detroit’s engines keep trucks, buses, heavy machinery, and industrial equipment running strong. Whether you're hauling freight cross-country, bringing timber out of the log trail or powering industrial generators, you depend on your Detroit Diesel engine to perform.

But even the toughest engines need the right technology to stay at peak performance. Your ECM (Engine Control Module), PCM (Powertrain Control Module), and TCM (Transmission Control Module) are the brains of your engine. When one of these fails, it can lead to loss of power, transmission issues, poor fuel economy, and downtime—and downtime costs money.

At Car Computer Exchange, we offer high-quality, remanufactured ECMs, PCMs, and TCMs to get your Detroit Diesel engine running like new again.


Why Detroit Diesel Is Built to Last

Detroit Diesel has a longstanding reputation for durability and efficiency. These engines power some of the hardest-working vehicles and machines in the world, including:

Freightliner and Western Star trucks – Reliable power for long-haul and heavy-duty trucking.
Construction and industrial equipment – Found in dozers, excavators, and heavy machinery.
Marine applications – Trusted in boats and marine vessels.
Buses and transit vehicles – Powering public and private fleets for years.

No matter what your Detroit Diesel engine is powering, it needs a working ECM, PCM, or TCM to run at full strength.


Signs Your ECM, PCM, or TCM Needs Replacing

If your Detroit Diesel engine is acting up, your control module could be to blame. Here are some common warning signs that it might be time for a replacement:

  • Check Engine Light That Won’t Go Off – If your engine is throwing codes that basic repairs won’t clear, your ECM or PCM might be failing.

  • Loss of Power – If your truck or equipment isn’t delivering the power it used to, a faulty ECM could be limiting performance.

  • Transmission ProblemsHard shifting, slipping gears, or delays can be a sign that the TCM or PCM is on its way out.

  • Poor Fuel Efficiency – A failing module can cause excessive fuel consumption, costing you more at the pump.

  • Hard Starts or No Start – If your Detroit Diesel engine won’t start or has trouble turning over, a failing ECM might be the culprit.

Ignoring these issues won’t make them go away. Replacing your ECM, PCM, or TCM now can save you from bigger (and more expensive) repairs later.
