Thankfully trans psi is higher than coolant psi, so just ATF in water. Changed radiator and is all good.

Still sucks though. But that’s one reason I went with a manual radiator in the Polara. That and I put a stand-alone trans cooler in front of it from a 2md Gen Cummins. It oughta stay nice and cool
