Kate, thanks. Dont really know what you can do to rectify the situation. My only recourse since I am so dependent upon my truck for business is to buy an aftermarket valve body and install myself. Problem is I cannot afford it and I dont know if the PCM can be reflashed to eliminate the regen codes that according to the service manager at Ram says they are related. If I install my own valve body can you convince Ram to reflash it for me?
