    We put a 2003 Cat C7 engine in a 2008 Ford F750. We had the ECM reprogrammed to the Ford truck. The engine runs great. The problem is the TCM & ECM won't communicate. Has anyone had this problem & how do you fix?

    Ok there is not much to these engines i have a few questions. 1)injectors the same. 2) horsepower the same. and if they are just swap the ecm from your old engine to the new one. it should fire right up. if the injectors are different you may have to swap them. if you swap injectors send them out to a injection shop and have them tested. a lot of failure of these engines is injector related. let me know how this works out.
