Water in transmission fluid?
Hey guys, hoping this forum isn't dead.

A couple of weeks ago I changed my transmission fluid on a Celica I just bought. Today I jacked up the car replace the crush washer on the drain plug and when the new fluid (two weeks old) started to flow out it looked choclate milkish so I'm thinking there is water in the trans fluid.

I have a theory that because I didn't replace the underbody plastic the vent on the bottoms of the gearbox may have picked up so moisture from the road.. that's my best guess because I'm pretty sure I couldn't have damaged the coolant lines in the transmission pumping new fluid in. Has anyone had any experience with anything like that?
