Getrag rattle

I wanted to get a video of the sound of the 2.8L engine in my '88 Fiero with the newly installed CompCam 1.6 roller-tip rockers, but it's difficult to hear much of anything else over the clatter of the transmission! The notorious Getrag rattle... ugh. For anyone not familiar with this rattle, it's "normal" with this 5-spd tranny, and the sound disappears when the clutch is depressed. I should shoot a second video while an assistant holds the clutch in.
