While cleaning and regapping my plugs sprayed some Carb cleaner to get some crusty stuff out of the area, it dripped onto the trans and pools in a low spot, so I clean it up and notice a rubber hose coming out of the trans (automatic Aisin-Warner 50-40LE) there. I had never noticed it before so I following it from the trans (mystery hose has the "?" marks around it), loops around the front of the battery, then heads to underneath the coolant tank and abruptly ends. I can only assume it is some sort of pressure drain (much like the one on my battery) and that it should not go anywhere. So what is this hose? What does it do? Where should it go?
