How do you change the transmission fluid on a 2002 Saturn Vue?

Well for one, if it's a manual transmission...you don't.

If it's an automatic transmisson, there is a drain plug right underneath the transmission. It's easy to see.

wrong. there is no plug for transmission you have to remove the pan and replace the gasket. where the transmission plug should be will be a gear box if u remove that plug u will drain gear oil.
