Well, I took it to my local shop and they pulled the tranny cooler and pressure tested it. They found a hole on the inside of the cooler allowing the tranny fluid to get into the coolant system. I'm not sure why the coolant didn't get into the transmission but the fluid there was nice and clear.
The fix was to plug the holes for the transmission lines at the cooler and install an aftermarket transmission cooler in front of the radiator. I've always wanted to do this anyway so this was motivation to do it.
The stock Packard trans cooler has been the subject of discussion before. When I first bought my 55 Pat, I thought that cooler was an tranny leak waiting to happen. So, one of the first mods I made to my Pat was to remove it and replace it with a modern air cooler mounted in front of the rad. I even found a standard lower rad hose that would replace the two couplers and the cooler (Goodyear #60706).
Just another example of a "mod" that prevents future headaches, if you are interested in that kind of thing.
