Hello from south, south, south Texas. The ECM burned out on my truck. Won't shift into overdrive, speedometer does not work, battery won't charge etc. Tried getting it rebuilt with a company in Jacksonville, Florida and they can't. They are sending it back and charging $120.00 for a diagnostic check. Can't find a computer. Help. Blueheeler1

Check out Rock Auto or auto parts store. Rock Auto shows as having them available for less. I would check them out.

I tried Rock Auto, they show they have 1 and when you try to order it's not available. I also sent the module to AES in Jacksonville, Florida and they contacted me to say the module could not be repaired, they were charging $120.00 for diagnostics and shipping it back. The ECM number is 56026860. Can you retrofit to pre-ECM? 1993 Dodge D350 Pickup 5.9 Diesel Turbocharged & auto tranny. Won't charge or shift into overdrive. Great truck!! Hate to park it due to a computer. Blueheeler1

That is terrible. I had an old 87 Jeep Comanche that the ecm went out on. I went to the local junk yard and found a replacement. Ended up working. You may have to go that route. I checked auto zone and they have 4 different models available. Their remanufactured ECMs are from Cardone. Converting to pre-ecm may be more trouble than its worth, but may be worth researching if you absolutely can not find a new ecm.

Check out http://www.car-part.com. They network with auto salvage yards across the country. I just did a quick search for a '93 350 diesel auto trans and a couple results turned up.

Toggle switch for the OD, and a voltage regulator, can get you home, at least.
Oh, and, THERE IS NO G!!!!!

How do you know it's the ECM ? Lots of issues cause the problem you're having, and the ECM isn't usually the culprit. How did you diagnose the ecm, if I might ask ?
