So here's the skinny:
'02 bugeye wagon, 151kmi. No mods, save the intake. 5-speed.
I'm getting a whining/whirring sound coming from what I've narrowed down to my trans. The sound starts about 20mph, and gets louder and slightly higher pitched from there. Happens with clutch engaged or not, definitely not the brakes or (from what I can tell) the half shafts. Definitely not wheel bearings as there's no rumbling, grinding, etc. Also not coming from the rear diff.
My local mechanic told me it's the counterbalance shaft in the trans....which I'm very iffy about.
Here's the sound clip. You'll hear it start up, a few shifts later it gets very pronounced. I'm wondering if anyone can help identify this before I end up with a full trans rebuild or something.
