Wow That's an old diagram from Ken. It still works today just double clamp it.  Seems like today's offshore made hoses don't fit as tight.

I will be running -6AN hoses from the trans to the cooler, I bit and paid $21.99 for the stupid expensive -6AN > 5/8ths barb fittings. :x

i would go Feed bottom-out top TO Feed bottom - out top and then the trans.
that way it wont get air trapped in any of the coolers.
   
Most talk about having thick skin but thats just BS.
This damn attitude of "you didn't listen to us/me now you should burn in hell for it" really sucks.

I think the air would be gone about 10 seconds after the car is started.

I am thinking about putting an inline trans filter in too.

given the pressure differential, I suspect any air would be pushed into the pan and dispersed into the atmosphere

The factory turbo buick pressure line feeds the top and out the bottom.  I think the white coats at gm know a little more then what some say on the internet. Also having the aux cooler before the internal factory one will keep from heating up your coolant in racing conditions.

Normally, the external cooler is mounted such that the outlets are pointed to the side for hose routing convenience... .this should eliminate any possibility of an air pocket even tho the tranny line pressure should be sufficiently above atmospheric to force any air on thru the system and out the vent.

With regard to the factory cooler, you are pretty much stuck with factory routing unless you want to go to the trouble of changing  it around.

I normally see 120-130 degrees on the trans temp gauge at cruise speeds with the big external cooler I use.

160 at the end of the run. Shannonvilles return road is actually the bike track...and by the time I get back to the pits it's cooled to 150 or so. I had a link for a trans temperature chart in regards to what parts start degrading as the temp rises...but I can't find it. Dusty recommends not sitting on the footbrake/transbrake for more than 3-5 seconds...and I agree with him...as you can watch the temp rise dramatically.

What does the temp peak on the brake?
