As do I, hence the tranny flush, etc... I did recently.
No biggie, just wanted to point it out that it may or may not be the downstream sensor.
As I recall the upstream sensor was considerably more than the $25 I paid for the downstream... I haven't touched the upstream yet although when the time comes to change the upstream it doesn't appear I'll have to jack up the car as I did with the downstream.
