I recently purchased a set of transmission fluid cooling lines (3-piece) for my 62 300H from Inline Tube, nice product. I have an NOS in-line filter...there isn't one on the car at the moment, and I'm wondering if club members can provide any guidance on installation. While the transmission fluid looks OK, I really don't know about its condition.
I'm inclined to drain the existing transmission fluid and replace with fresh material, however, I've heard that this procedure can be somewhat "tricky."
