So, I pulled the trans cooler lines off the rad this morning. I hosed the cooler out with brake clean, then followed up with blowing it out with compressed air. I capped off one end of the cooler, and put a nipple on the other end. I connected a vacuum pump and drew down to 30 lbs of vacuum. \
Then I pulled the radiator cap, confirmed the rad was full of coolant, then put a pressure tester on the cooling system and pumped up 14 lbs of pressure, while the vacuum was on the trans cooler. I let it sit for more then an hour, both gauges never changed. Would that have been long enough to show a problem? I would have thought that with pressure on the cooling system and vacuum on the cooler, if something was bad, it should have shown up in an hour, right? How long is long enough?
I'm going to move forward under the assumption that the water got into the trans during its improper storage before it got installed in my truck.I'm going to have the system flushed at a local shop. I'm paranoid enough now that I'm adding an outside trans cooler and will plug off the trans cooler in the radiator. When the truck makes it to the road, I will check to see if there is antifreeze in the trans cooler, then proceed with a radiator claim if needed then. The Rad has a "lifetime guarantee". By then, I should also know how the trans has survived the ordeal. Gene

Transman has a good idea. I think you've already verified that the radiator isn't leaking into the built-in trans cooler

That's what i figured was going to have to be done in one of my earlier replies to this posting. Been there, done that. Used those flushing machines, when i was a full time, wrenching mechanic, for a living.
