GTI 337/20th Anniversary :: 2005 - Accidentally Downshifted To First Gear At 50 Mph / Tranny Making Noise

I drive a 2005 Jetta GLI 1.8T 6 speed O2M transmission.

I was redlining 1st 2nd and it wouldn't go into 3rd tried 2-3 times finally did. but I believe it went into first instead! I think I was driving like 50-60 mpg I don't know. Anyways it JERKED BADLY. I think right after it started making a noise. sounds like the manifold or downpipe gasket. I know the flex part of my cheap downpipe started like tearing and ripping, so I thought that just broke thru. maybe I don't know. I drove the car home. tranny worked flawlessly. every gear very smooth like always. (redline tranny fluid). at home I jacked it up took the bumper off. and listened where the sounds were coming from. not power steering. it sounds like a hose is loose. but I checked nothing. I put my ear next to the tranny. sounds like it coming from there. nothing changes when I depress the clutch. when I start driving the sound goes away I think. can't hear the cause of aftermarket exhaust. and stage 2 chip tunning APR 93.

After all, that believing it the downpipe. I put everything back on and drove it about 10 miles and this other sound came in. happened in 2nd after like 4-5krpm. maybe it was there from the beginning. I drove it slowly under 3k. but this sound is like rattling and kinda vibrates the clutch a little. it happens after I accelerate and take my foot off the gas pedal. kinda when slowing down. I drove parked the car 2 hours later drove it home and 2-5th gear was making this rattling sound now.

I don't know what to do. I need to drive a car. should I drive it or not? do I need a new tranny/ is it fixable? should I park the car and take the tranny off/

how tightly are the flywheel bolts suppose to be tightened? something loose?

I did an auto to 6-speed swap.
