While I thought I had previously plumbed my Aux cooler before radiator cooler, I assumed incorrectly the direction of flow. When I saw what I thought was the return line, went to the front port on Tx, I decided to open my Magnefine filter. The Exterior of the media pleats were cleaner than the interior.
The internet later confirmed that the rear port is the return port. Gee, I guess I should have checked that 7 or 8 years ago when I added the Magnefine filter.

So I had the Magnefine inline filter on backwards, and my Aux Tx cooler was plumbed after the radiator cooler.
My pan was pretty clean, not much ferrous sludge on magnets. I added two neodyium magnets to pan last pan drop in addition to the donut magnet. The donut magnet had very little ferrous sludge on it. The Magnefine filters have a bypass if th eelement gets clogged. Good thing mine did not get clogged as it would not work plumbed backwards.
I made new steel lines out of the Napa 5/16 brake line. While I took all stress off the lines, and cleaned the mating areas very well with PB blaster, there was no getting the old lines off without destroying them.
There is a brass adapter screwed into the transmission, and this came out when unscrewing the flared fitting from it. I did try and hold the brass insert and turn the compression nut, but there was no way to achieve enough torque, so out came the brass plug too. And I had to put this in a vice and use a 5/8 flare wrench and a lot of muscle to separate them. no way could I have achieved that amount of torque laying on my back under the vehcle a the angles I was allowed.
Having to cut the lines to get them off, made making new lines harder as the template was destroyed, but the napa lines bend pretty easily, and my main concern was that they did not hit the kick down rod or the shifter linkage. Also I made the lines differently, with the return line going to passenger side where I mounted my derale external filter mount.
So now my plumbing goes to radiator first, then Aux cooler and then to my Aux filter. I am using a Fram Ultra XG16. DO not confuse the Fram Ultra with the orange can of death fram (tough gard) that the internet has made into a pariah. The Ultra is a very good filter, especially for 9$. I could use a larger filter like the XG 8A size, which I use on my engine.
The Tx pan got a new filter and gasket as well.
I put the Aux cooler in between the radiator and the fan, instead out in front, simply as it was more convenient to do so. There is still over 4 inches of clearance before fan blades.
I realize it would likely cool better out in front, rather than behind radiator, but I will likely have to collect some data, and if I can't keep it 180F or lower on the return line, I will add a pusher fan in front of the radiator where I have the Aux cooler attached.
Am doing a coolant exchange too, then valve cover gaskets, then all new ignition components. The ignition components could likely go a lot longer, but Oh well. I got a smog test coming up soon, and will be racking up some mileage the week after next.
I could not get the plugs out of the block, and still have ~1.5 gallons of old coolant in there. not happy about that but will try again tomorrow as I have not refilled system yet. I did swap out my lazy slow to open Motorad 195 T stat for a new old stock made in USA, 195f Stant superstat. Cant go to a 185F with fuel injection. Did that once, Lost nearly 2 MPG highway.
