    Replacement PS / trans cooler options

    As the marauder starts to approach 20 years old, she's showing her age. Rubber hoses are decaying, getting a few leaks here and there. I want to go through and do a pretty good service / replacement, especially on cooling related parts.

    One thing I'm struggling to find a replacement for is the combo PS / trans cooler as mine is leaking at the thermostat. The part # listed here is YW1Z-3F749-AA. I've had zero luck finding that exact part number. What are folks using for replacements now? I know ones from CVPIs should still be available, but I've no idea of cross-compatibility. Every OEM Ford site I've checked insists basically every cooler is compatible with every panther...though I have my doubts lol.

    I'd install an aftermarket trans cooler in series with the factory cooler.

    Definitely planning on it! Problem is, it's leaking, so I need a viable replacement for it to go along with an aftermarket. Hoping there is one from another panther that is cross-compatible?
