alright.. i got an 04 civic SI, 52k miles.. for some reason everytime I shift from 3rd to 4th it grinds.. loudly. kinda like when you try to shift without steping on the clutch. The only way it wont do it is when you step on the clutch, let the engile go down to idle, then shift.. also, when the car is still cold. is it the clutch? synchronizer? tranny dying? Also..... there's a loud whistle on 5th gear, sounds like its coming from the intake (lower left hand side) or obviously the tranny.. it sounds kinda cool but im not sure it should be there...
The engine is stock.. AEM cold air intake, aerospeed lowering springs, full catback exaust system (headers)...
any thoughts?? ideas?
