What is causing the Fluid to leak and most efficient fix.

What is your question?

So about 3-4 weeks ago i started hearing a faint chirping when i started the car. I checked the belt in the front by the fan and saw nothing out of the ordinary. I've noticed more recently when im driving it seems to shudder or shake between 30-40mph when shifting but below or over that speed it is smooth for the most part. Monday i pulled into a parking lot and got out and noticed it was leaking fluid.Like it was a nice size puddle too. Fluid was a orange reddish i assumed it was Anti-freeze because that was the same cooler the coolant tank was stained when a noticed a couple weeks back it was Dry. After alittle more thought and research mainly i filled my coolant up again a couple days ago and its like a clear neon green color 50/50 all weather. So i was driving to work today and noticed a increase in the shuddering when i got to work i popped my hood and noticed that this liquid had came out again but this time up by the top of the belt by the fan and gotten on the under side of the hood and some of the tubing and connnecters there by the belt.I could also smell it burning off which is what alerted me to looking under the hood. Same smell i smelled when it leaked bad a few days ago. There was some faint smoke but i thought it was the fluid being burnt off. If you could point me in the right direction it would be appreciated. Honestly its probably a few things but if its the transmission i would like to know so i can get that looked at ASAP...
