To clarify, you went to a tunnel mount?

I installed the 4l60e torque arm relocation mount that replaces the stock transmission crossmember

I Have the one for the TH350, and I have no vibration. I can tell you though that your y-pipe/x-pipe is nearly impossible to route around the torque arm mount bracket on the crossmember, so that might be your problem? A lot of guys go with a custom y-pipe/xpipe setup I'm learning.

I checked to see if the y pipe was hitting or rubbing anything and no luck
