This is my first post so I hope this is in the right place! I've recently come across an extremely annoying sound coming from the engine area when shifting 1-2 and sometimes 2-3. If I get it up in the 3,000+ RPM range and shift (or simply let off the gas when the engine hits higher revs) it makes a squeak/chirp noise (no it is not boost blow off etc. and I am not chirping the tires). If I shift out of 1st at a lower RPM (and baby it) and the engine isn't under very much torque, it does not do it. It only does it 1st-2nd and sometimes 2nd-3rd but never 3-4 etc. This led me to think it was the air box rubber grommet that everyone is talking about. I greased it liberally and still have the noise. I really don't think it's an air leak of any sort because if I hit any significant bumps it squeaks as well. The only other thing I can think of it being would be an loose or bad engine mount (RMM or side mm?). I can't find any threads or posts regarding the sound it would normally make, so I have nothing to compare it to. I am attaching a link to a 10 second video of the noise from the cabin. I'm shifting 1st to 2nd and as soon as I push in the clutch you can hear the chirp/squeak and shift to 2nd and then 2nd-3rd (it's very hard to hear so listen carefully). This is really frustrating so any ideas/suggestions what it might be would be awesome. Like I said, it's only when the engine is under a load, then isn't and the engine moves around, or I hit a big bump causing movement somewhere in the engine bay.
