DYLBER

Hello everyone, i own a 2010 g37x sedan and for the past few months I've have a squeal while accelerating. The squeal is in sync with the RPMs so when i let off the pedal it stops but when i push back down on it, i hear the squeal. Ive replaced every pulley besides the alternator pulley and the steering pump. Ive also replaced the serpentine belt. I do have a leak coming from the transmission seal but idk if thats what it is. I have a 7at. Please let me know if you have any ideas what it could be, the squeal is getting on my nerves and i just want it fixed.

Thank you
