Did this gunk just appear recently? Have you looked at it before this. Check the oil level and the trans fluid level and see if one of them is low or contaminated.

it was like this before, ive been slowly giving it a tune up i had just changed the oil and the oil filter, the next day it was like this, the gunk is like watery chocolate, i just looked at the oil and trans, the oil has water in it, so is this a blown head gasket..

If the oil has water in it, that is serious. It could be a blown head gasket but if there was no previous overheating, it's not real likely. It's much more likely to be a bad intake manifold gasket or if it has one, and bad engine oil cooler. Either way, DO NOT drive it until the engine is repaired, not even around the corner.
