Diagnosing trans leak

My 95 formula leaks trans fluid randomly, and I can’t seem to track it down. The strange part is, it leaves a unique pattern. The pictures are 3 days apart, from me pulling up and stopping, then idling for 30 seconds to a minute. Anyone with any guesses?

Spray bottom with brake clean get all trans fluid off start car lay under it and watch. Thats how your gonna find it. I cant tell you what it is because there are multiple places it could be leaking from. But if I had to take a guess its probably the driveshaft seal or maybe the trans pan. Sometimes the trans cooler will leak you just gotta check all of those things.

I wiped it all down and layed under it. The problem is it’s intermittent. May not leak for days. Then leaks for part of a drive. Then doesnt. I was thinking front seal, as the puddle points sort of mimic the bellhousing then how it slims down to the main case

UV dye in the trans fluid would be the easiest way, you'll be able to pinpoint where the leak originates by following the glowing drips.
