Transmission late shifting?

The vehicle listed above is the XLT model. So, today I was charging my battery on my car and I saw this (see picture below). It was not there a week ago because I topped of my windshield washer fluid and I didn't see it at that time. I used my finger to wipe some up and this is what it looked like (see picture below). It either smelled like engine oil or transmission oil i am not sure which one. I can also tell you that it had some little metallic stuff mixed into the fluid as well. The transmission oil has also never been changed at all. I also drive the car everyday and it has not been driving any different however it has been shifting at higher RPM's than normal. Also I just got a remote start and I've been using that all the time. Any help you can give me would on what is happening would be greatly appreciated.
