1989 (when i purchased my 1981 van used)-2016: apart from a brief dipstick leak around time of purchase which was resolved, no issues.
2016: Changed transmission fluid (ATF+4) and filter. Installed re-usable gasket 2464324AC with special bolts 6036402AA. Worked slowly and carefully, tightening bolts to spec.
Over the past several years i’ve noticed leaking transmission fluid from around the gasket/pan edge, especially at the front passenger corner:

Some bolts were loose. Retightened to spec. Do they need thread locker or something?
Leak persists. It’s become much more severe than in the photo: the cardboard was discolored over a very wide area directly under the transmission pan, with a red tint, not brown like motor oil.
Transmission works fine unless the fluid gets too low. Prior to 2016 i never had to add transmission fluid; now i occasionally must.
What am i missing? What do i need to check/do?
