The Dreaded Tranny Pan Leak

I have checked the dip stick tube several times, no luck, it is sealed up good. I was hoping that it was the tube o-ring it would have been an easy fix.
It sounds like you know what you are doing. Good Luck.
I know what you are going through.
Don't throw money at it like I did, I spent hundreds until I found the 25 cent O-ring fix.
Chime in when you find the cause, I'm curious. Thanks
