Gearbox noisy when in park?

[///AMG55]

Hello all,

Have noticed a clunking noise coming from the gearbox when in park. But when in drive or reverse, the noise goes away.

I have just replaced the torque converter some months ago.

If you guys could help, that would be great. Thanks

do you know if it comes from tranny and not from rear axle?
I had a small clunk in reverse when hitting the accelerator, it turned out to be a soft tranny mount.
had tranny mount replaced, noise gone to hell, no more clunk.

couldn't really hear the sound in your vid but if it goes away when trans is loaded could possibly be linked to your TC change.
Is it definately coming from Trans could it be from somewhere else? Was the replacement new/recon or 2nd hand?
