My ECM and TCM are dirty and was wondering what the best way to clean them? I'm thinking some soapy water and a rag but obviously don't want to ruin any of the internal electronics.
I just took them out of the truck, since its easy enough to do, wiped them down with simple green. Then took some Mag polish and polished them up, I know im weird. But I cant resist polishing something that can be polished.
