Here's a few photos I stole. There is a smaller inner boot that seals the shaft to the top of the tower (this keeps oil from leaking out of the tower down the transmission.) Then there is a second, bigger boot that seals between the shaft and the black metal ring on the body.
On some cars these are separate boots, on others it's a single piece that combines the two.
If these are missing or torn you will get a TON of transmission noise in the cabin even with a good transmission. They are generally installed after the transmission is in the car.
