Hi there I'm looking for some insight and help, I've got this wierd high pitch noise that only happens under heavy load(wot) and the noise only happens between 3-4rpms, this noise sound sounds like a high pitch whistle/squeal, and it goes away after 4k rpmsI have a 1.8L automatic and have 53560mi, I think I'm overdue for a trans fluid flush, and a coolant flush. But I I've checked the serpentine belt, all the pulleys, use a scope the listen to the water pump. Everything is fine. Oh and if gradually accelerate from idle and past 3500 rpms and gun it, I dont hear the noise. I've also replaced the oil pan, but everything was done precisely...also I've never heard this noise before I changed the oil pan as well, there are no leaks coming from the oil pan, but the center windage tray clip broke so if you push the center part of the windage tray does flex....help me, this only happens when I mash the throttle between 3-4k rpms and it happens through every gear.
