Function of this part
The engine control module (ECM) is the electronic brain of the engine. It reads information from sensors and commands fuel delivery, timing, and other actuators to keep the engine running properly.
Why this part matters
Without a functioning ECM, the engine will not start or will run poorly. A correct, working ECM is essential for performance, diagnostics, emissions control, and protecting the engine from damage.
About the brand
Allison components are commonly used in commercial truck and equipment applications where dependable performance and proper fit are important.
Fitment & usage
Used OEM parts are a smart choice for controlling repair costs while still using original-equipment components. Always match the OEM part number(s) listed to your existing part, and consult your service manual, dealer, or technician if you are unsure about fitment.
Note: Because this is a used component, normal signs of wear such as scratches, discoloration, or light surface corrosion may be present. Refer to the product photos and information on Second Truck Parts for the best representation of the part you will receive.
