Sorry to say that it is almost impossible for us to diagnose such problems as we do not know the type of noise and where it is coming from.
Where engine and/or trans noise are concerned, you need to have someone check and test for the source.
Does the noise appears in Neutral?
It could be the torque converter or the mainshaft bearings from your description.
