I'm wanting to run transmission fluid through the internal cooler in my CAS aluminum radiator. I have previously run engine oil through it but stopped when I had some issues with engine going south. I have sprayed some brake cleaner in the cooler and I am getting small metal (aluminum or ??) flakes out the other side. Question....how can I clean the cooler out so I can be confident that no metal will make its way into my tranny? Iwould like to power flush it but know that water is a big NO with transmissions.
