Strange noise coming from shifter linkage

[4t9ers]

So I'm wondering if you guys can help chase down an annoying noise.

I have a 97 gsx manual with a 6 bolt swap and a rebuilt transmission. Over the course of driving this car, there's always been various wind/air leak noises. For example, close a vent when the heaters on and it starts whistling.

Well, there's always been a constant "wind" noise that I've pretty much given up on finding, until this week. While driving down the freeway, this noise was really getting to me since it was raining and I had the windows up (I usually just have them down since the AC is iffy), and I happen to push against the stick - and the noise went away! But then I let go of the stick and it came back.

This happens in any gear at most any speed( not at a stop). Push against the stick in third, it goes away. Pull against the stick in forth, it goes away. I can even get up to freeway speed, put it in neutral, and lightly push the stick towards a gear, and, if it doesn't go away completely, it'll at least dampen the noise.

I pulled the center consol to make sure the base plate was all secured since I thought the "air" noise could be coming from there, but it's all secure.

So, sorry for the wall of text, but can anyone put a finger on what could be causing the noise?

Thanks all!

Have you checked the linkage at tranny? Before I put in the skate board bearings in their was a lot of play side to side with a lot of rubber still their. So maybe if your rubber is gone and their is slack in linkage it rattles? Only think I can think of right now. That's where I would start.

Is the sound more forward in the car or is the sound right their at shifter? Could be where it goes through fire wall Thinking outside the box their.

Waiting for my GF to get off work in my GST sitting roaming tuners on iPad.

I haven't done the skate board bearings yet, that on the to do list tho.

As to where there sound is coming from, it seems to be coming from directly beneath the radio, and in "front" of the shifter. Unfortunately I've been in the drivers seat, so I haven't gotten my ear too far down there yet.

I'll do my due diligence and check the firewall next. Maybe see if the the linkage is moving/flexing as it goes thru the firewall??

I'll try to take a video for you to see. (Wants the best way to post a video anyways?)

So I did the skateboard mod on the linkage under the hood, and the noise still persists.

Also, while I was driving I started twisting the rubber grommets and sleeves, and the noise got louder...

Is there some kind of adjustment that can made here, or do you guys think new linkage is in order?
