Ok. So i'm driving around yesterday and i parked my ride. I then notice dripping green fluid coming from the transmission where the engine and transmission couple. What would be the issue.

first check your heater hoses, probably one of those.

Heater hoses. Tighten the clamps. Also is the stock turbo watercooled? If it is then check those lines too. Looks like I'm gonna have to study my RB a lil bit more.-Alex

If you went aftermarket turbo (oil only) then did you plug the coolant send/drain?

can't find anything leaking before the transmission. It's coming directly at the front most part of the transmission. I have a chip off the transmission. and thats where the coolant drips from. Only drips after i finished running the engine for a few minutes. When it sits no leaking occurs.

Did you check those heater hoses yet?

The reason it drips after running is that the pressure in the cooling system increases a bit when warm. After the engine cools, there is usually a bit of vacuum in the cooling system, which will slow down any small leaks.

ok it was a heater hose that wasn't fully tightened directly above the starter it was a big hose and a line that tapped into it was from the throttle body. Thanks for all the suggestions fellas.
