I am in need of a good public flogging. But first a little background so you all can determine my level of guilt. I am the second owner of my 04 MT. It now has 105000 miles. Bought it with 85k on the clock and today is the first time I've changed the transmission and differential oil. And to my knowledge this is the first time it has been done.

The "oil" if you can still call it that, in the transmission was grey and had a closer consistency to water. Please. Shame me. Let me be an example for others.
