Possible vacuum leak?

I was hoping it wasn't a torque convertor lol. Maybe one of these days I can get the tech ll and go for a cruise and watch what the tc does. But yeah the sound I hear is like a loud whooshing and my wai is nowhere near as loud as it used to be. Maybe due to this new noise masking it? It's coming from somewhere on the passenger side just not sure where. Sounds like it's somewhere around the Schrader valve.

I'm sure you understood me, but to clarify, when I said the rpms jump anywhere between 1-300 that's cruising or a hill. When they jump up 600 that me tapping the brakes lightly to unlock the tc. I've run it in 3rd up the hills and it still does it, but definitely not as noticeable. I'm assuming because the rpms are up. If I go balls out and drive the car hard I don't have issues with Surging. Nice smooth gear changes and it doesn't miss a beat. It's like the Surging issue is only low rpm based.

My car was doing that last week for like a day and suddenly stopped I was thinking it was the torque converter but it hasn't done it since so i forgot about it till i read this.

Probably is tc. I dunno. If it makes any difference I have a whole lotta oil in the upper intake. When I did vac test I saw oil where the brake booster connects and so I stuck a qtip into the nipple and it's gooey oil.
