I have a 92 venture I have the same problem 3000 RPM she chirps very loud pull in the clutch it stops it’s not coming from my windshield stay below 3000 RPM or go over 3000 RPM it goes away you may hear a slight bit below 3000 rpm nothing that would bother anybody or even noticeable but I notice a little bit, try different oil change the oil no difference first gear slams in sometimes all the time smooth as glass
