Trying to find the hose connection, this happened. When sucking on the hose, air can be heard bubbling through some liquid, sounds like it is just past the end of the tranny. When blowing on the hose, liquid (looks like red tranny fluid) comes out the side of the engine/tranny close to the firewall. Being 6'2" I find it very difficult to get curved aroud enough to find the leak. The hose itself is factory clamped onto a cowling that seems to be bolted to the front (of car) top side of tranny. The tranny is operating fine, but the Ford dealer sold us a fluid change weeks back, took this hose and tucked it behind the battery, so it looked like it belonged there. Do you think this has anything to do with the CEL being on? I am waiting for a vacuum meter to arrive to see how much is being exerted through this hose. I am still confused about the small ground strap, clipped to the hood hinge, bolted to the inside of the firewall, and flapping on the other end. It is about 14" long, and seems to go nowhere. The bolts it could reach(inside engine compartment) do not seem to have been removed> Thank you one and all for your responses......3DUB
