if you're talking about the 'green' thing that's commonly called a dashpot, if you're talking about what's below that it's the VCV (vacuum control valve) and that is what can cause problems with the trans.

If you replace the VCV be sure and replace the seal where it mates to the IP, those seals deteriorate.
