Weird noise at 1800-2400 RPM

Any ideas what it could be? It happens in all gears, I thought it was 4th at first, but then I tried it in all gears and the sound happens. Oil changes <4m miles, last one <1k miles ago. Tranny flush 1mo ago, it's been happening for 2mo. The tranny oil cooler lines were leaking, but was fixed. The car is boosted so maybe the flex plate?

It does sound like your flexplate is broken causing a vibration. It is either that or the torque converter. It is possible that you have some exhaust pipes rubbing or turbo pipes rubbing on something.
