Torque converter rattle??

[Steelrat]

I believe I have isolated the rattle to be that of the Torque converter. It is now rattling when in 1-2-3-D - R, but not in Neutral. It makes the rattle noise between 2000 rpm and up to 400o rpm depending which gear I am in.

I have found some references of a “mystery rattle” noise complaints that can occur after rebuild, or well within the warranty period . Frequently, the noise can be traced to the TCC piston and damper assembly. I am not sure if this is accurate.

Thoughts?
