T-45 Grinding?

[squares98]

After I took my car to the dyno my transmission/clutch or engine sounds like shi.. crap under too much load until 2,000 rpm. If I'm going uphill the sound will last until 2500 rpm at just a hair above light load. If i baby the throttle at low rpm(1500-2000) it's fine but if I give it more gas sounds like a broken or loose object or other spinning around in the clutch/transmission(almost like detonation). The clutch had 2k miles on it and the engine had 1,500miles, the t-45 has 110k miles on it and never made a noise like this before. It shifts fine too, no grinding. They never saw it but they said it might be the T.O.B. but i know the T.O.B. sound and that is not the whistle is know. This sound is a grinding, rattle metal to metal sound. Any Ideas .
