It would seem at this point the OP would also (or instead) need to send the transmission fluid for testing (if they are so inclined to go that route).

And they do transmission oil testing as well:

Although antifreeze is listed on the tranny report, I'd confirm that they do check for that.

 

You may want to consider getting a new thermostat and a water pump, or at least new gaskets for these two parts. Maybe take these two parts out to clean them up, and sacrifice the gaskets that are in there for these right now? The commercial coolant system flushes may be a little harsh on any of the older gaskets it comes into contact with..

 

First thing is to find a good replacement radiator. Then to flush the tranny. Probably gonna start with draining the tranny at the pan. Was mentioned to me that with the coolant in there now, that some parts can start to rust.

Not sure if I should just keep the radiator in there or replace it knowing the new radiator will also get some slim in it as I flush both systems out. Oh joy!

 

went ahead and bought this radiator since I need it this weekend:

I figured that I could always return it if it gets too gunked up. I'm gonna be going through a ton of tranny fluid and I'll use water and radiator flush that I can buy from the store to see if it can help the cooling part.

 

update:
I drained the tranny, milky milky. Then I had to help with the baby, and that's as far as I got. Cold came in and not really wanting to go outside and work on it lol

 

You're going to need to do multiple flushes of the trans. I suggest the method of running the oil cooler line into a bucket and adding fresh to the trans at the same time. One of the tranny cooler lines drains straight into the pan. In hindsight the leak at the oil filter was probably fluid pushing out of the tranny dipstick.

 

Yeah I was gonna try the return line into a bucket. I actually got a free 5 gallon bucket from Chik-fil-a lol Smells like pickles but it will do!

I'm gonna go ahead and replace the orings for the oil filter adapter and then I can get a better idea of why it was coming out of there. The top of the dipstick to the trans was dry. Could have been coming out of the bottom part?

 

Oil leaks at the adapter for the filter is very common. I would assume that that common issue is its own issue. If the transmission's oil is mixing with the coolant inside of the radiator, then you will need to plug the ports in the radiator where the lines to the transmission go unless you replace the radiator. There is a crack in those reservoirs that allowed mixing. It is probably best to just replace the radiator. Chinese ones sent straight from the people's republic off Amazon are cheaper than a junk yard's prices.

 

yep, already have the replacement radiator, just need somewhat better weather to install it in. Now it's supposed to rain tomorrow and sat here...
