WOW... That bearing has been attributing to a lot of drivetrain noise I guess. All I hear now is the exhaust and the rattly interior.

So my transmission mount modification included a tube of polyurethane from Home Depot, a ton of packing tape, and some ingenuity.

Basically, I wrapped the whole transmission mount in packing tape, sealed off where the stock rubber is, cut a small opening in the tape and shot it up full of polyurethane. So I only filled in where the "Group N" has material. By taping it, I was able to mitigate how much air space ended up in there. Threw it in the oven for about 12 hours at 220*, and voila.

Not to say it compares at all to a true Group N or anything, but it is notably better than stock, and only cost $5.85 instead of $80+

Wish I had made a video of the noise this one made while driving. Really sounded like the trans had rocks for gears.

What are the chances that the banging coming from the tranny could have tripped my knock sensor? My car feels like it's running a lot stronger and meaner off the line than before. I don't have a scanner right now, but it feels like it's pulling a lot less timing.
