I went to put the plastic undertrays back on so I could move the car out of the garage for a bit, and for some reason decided while I was there I should tighten up the trans cooler lines that have a slight leak. Some of you can guess where this is going. As I turned it I noticed it wasn't really getting tighter, then I noticed it had some side to side play. The adapter fitting then stripped out of the trans. When I checked the other one it had the same side to side play and after a couple wiggles came out too. It looks like the problem is the threads in the trans don't start til a few mm in, and the adapters are very short, so there's only 2 threads of engagement. Rather than get too annoyed at the shop that supplied the fittings or the shop that installed them I'm just trying to be happy it happened in the garage and not while driving as that likely would've resulted in a destroyed transmission.
I still have the stock lines and could put them back in, but they're 29 years old. I have nice new AN lines already the correct length and hooked to the cooler so I'm hoping to find some longer adapters, top up the fluid, and be good to go.
The mess it snowballed into:
