Help identifying a part

Hey everyone! A mechanic sent me this picture of a part that needs to be found online since they couldn't source it. He said it's "just a few bolts" to replace it and that it "stabilizes the transmission but isn't causing any issues as-is." The reason for replacing it is that it's causing a rattling sound. It doesn't quite look like a transmission mount to me, but I'm not sure. I can't find where I wrote down what it is (this was a little while ago), and the shop doesn't have anything on file. I'm hoping to find the part before taking it back in. It's a 2000 SR5.

 

Dynamic Damper.

 

Thank you!

You'll have to source it from ebay or a junkyard.

Might be worth unbolting it and seeing why it's rattling. They don't usually make noise even in old age. They are really just a passive thing that reduces certain frequencies of vibration. They are more to make the car feel calm and smooth for new buyers. Once you have 200k miles and a whole bunch of wear and tear, they probably don't do a whole lot.

 

Thank you so much for this info. I did some reading, and it's such an interesting part.

I also found this Reddit thread on fixing the existing part, so we might try that if we take it off and the noise/vibration is worse. I haven't seen it on eBay, and it sounds like some vehicles are okay with it removed.
