Has anyone had any problems with a noisy transmission. I have a 94 Chevy Z71, that the transmission is rattling probably from inside. Sounds like some inside is rattling but mostly in gear. When it is park, it is not that bad. If you step the gas while in gear, it rattles alittle more. Can anyone give me any ideas of where to begin.
I have about 160000+ miles on it.

THANKS
