hit up Matt at Silverfox for your AOD. I am running his Valve body, A servo and other parts. My 90 makes over 500hp and the AOD works perfect. Get the biggest plate style cooler you can fit for insurance.
Nothing wrong with those numbers. Even better if you've got the 87-92 forged pistons! Check your #3 main bearing and a few rod bearings to make sure there not excessively worn and go from there.
hello everyone, Took motor apart and worried about what I see on the middle crank bearing. Opinions welcomed, if I need a refresh I am screwed. The bores still have the machine markings and no ridge. Factory head gaskets and motor mounts to amazingly. Let me know what you think. The crank journal looks brand new.

Replace that thrust bearing if you feel the need
I would check the end play and run the bearings if they all look good like that

I see just normal wear
The thrust gets looking like that quick on one that has a clutch and is driven some hard
Just check the clearance and re use it if it's good
I just looked up the end play spec again it is .012"

I'm with you here, I'm so lost. My stock 5.0 has 170k miles and I still bounce that thing off the rev limiter all day.
Unless you are just extremley bored I would have left the motor together, could do more damage putting it back together if you don't know what you're doing.
I would opted for just changing the seals and throwing in a used T-5 when you put it back together over a set of aluminum heads. Doesn't matter how "strong" or "weak" the AOD is, it's so sluggish, I'm not sure it's even possible to damage a stock 5.0 with that tranny.
I do admire GN for having the guts to tear it apart, but I feel it was not needed.
I would oil it up and stick it back together.
As for the auto trans, change the oil, stick a shift kit in it and ride.
A gear change would be in order but a trans swap? Naw.

I did the same thing with a '99 Explorer motor that was supposed to be a cheap build. ARP rod bolts that needed to have the rods resized, ARP head bolts, new Lunati cam, the right valve springs/retainers/locks, forged pistons, on and on. One thing led to another, and my cheap build motor isn't so cheap anymore!
I feel your pain... NO such thing as a cheap build... I would rather use parts and a machine shop that I pick though, rather than buy a " rebuild" off of ebay..
