Image attached to thread. I have been having a ATF leak (in case it is not obvious from the image) and spotted this hose while trying to pinpoint the leak. Would anyone be able to identify the purpose of this hose and if it is missing a clamp? Many thanks in advance. (The image is facing the front of the car. Sorry I couldn't get a better shot.)

 

Can you provide us with the information about your accord like year, 4/6 cyl engine, transmission, trim (lx, dx, etc.)?

 

2000 Accord LX(?), V6 3.0, 4 door.

 

I think that is the gear position cable for your transmission. If the other end enters the cabin of the car near the center of the firewall then it is definitely a shielded cable for gear selection and not carrying fluid.
