Is your 2004 Dodge Durango giving you headaches with stalling, a persistent check engine light, or a frustrating no-start condition? A faulty Engine Control Module (ECM) is one of the most common causes for these issues, leaving you with an unreliable vehicle and a lot of stress. This pre-programmed engine computer is the definitive, hassle-free solution to restore your Durango’s performance and get you back on the road with confidence.
Common Symptoms & Your Solution
If your 4.7L Durango is experiencing any of the following, a failing computer is the likely culprit:
- Check Engine Light: Particularly for internal module codes like P0601, P0605, or P0606.
- Engine Performance Issues: Rough idling, random stalling, engine misfires, or a noticeable loss of power and fuel economy.
- No-Start Condition: The engine cranks over but refuses to start, often due to a lack of fuel injector or ignition coil command from the ECM.
- Transmission Problems: Harsh or erratic shifting, or getting stuck in ‘limp mode’ (stuck in one gear), as the ECM controls transmission functions.
- Communication Errors: Your mechanic’s scan tool cannot communicate with the engine computer.

You are purchasing a reliable, expertly prepared 2004 Dodge Durango ECM 56029028AE that will restore your vehicle’s factory performance.
Frequently Asked Questions
Is this ECM really ‘Plug and Play’?
Yes. We pre-program the unit using the VIN you provide during checkout. This ensures it’s ready for installation without any additional dealer programming or flashing required.
How do I know if my ECM is the problem?
Common signs include a persistent Check Engine Light (especially with internal processor fault codes), random stalling, no-start conditions where the engine cranks but won’t fire, and communication errors with diagnostic tools. While a professional diagnosis is always best, these symptoms strongly point to a failing ECM.
Will this fix my transmission shifting issues?
In many cases, yes. The ECM (often called a PCM in Chrysler products) controls both engine and transmission functions. Erratic shifting, getting stuck in a gear, or harsh engagement can often be traced back to a faulty computer.
What part numbers does this replace?
This module is a direct replacement for a wide range of part numbers, including 56028795AC, 56029028AG, 56029029AH, 56029145AC, and many others listed in the compatibility section on this page.
What information do you need from me?
To ensure perfect programming, we will need your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. You can typically provide this during the checkout process.
What is the warranty on this part?
This unit is backed by our one-year replacement warranty.
