Baffling to me noise (1 Viewer)

My 94 is making a strange as hell sound almost like a blow off valve noise after the trans is warmed up driving several miles. Only makes the noise when it kicks out of OD. It’s vary random, doesn’t buck shudder or shake. Shifts normal and it’s not a metal grinding sound. No leaks, fluid was changed way before noise started. I’m not entirely convinced it’s coming from trans

Does it happen when you toggle the OD button? Only while accelerating?

happens when accelerating going up grade or needing to speed up and downshifts. Doesn’t do it every time which makes troubleshooting it hard.
