This solved my problem. I thought it was an oil leak until I raised the car to notice it coming from the transmission. The leak was probably why it shifted a bit rough occasionally.

First, I called a dealer and they had the part for $9. I took it in the next week and showed them the photos to explain the leak. They had it fixed in an hour and cost me $77. Filled it up and no mess for me.

Not bad! No leak and smooth shifting! Thanks for all your help owners!
