Looked for loose hoses and found an open rubber hose looped up to near the top of the ATF fill tube. It's secured with a clip to the fill tube but just loops around and back down with no termination. Is this normal?

Thanks for any help!
1) Visual inspect for unmetered Air leaks.

The rubber hose looped near the AFT tube?

I always look for plastic (Air duct), rubber, and seals for PCV + EGR systems, that can go bad after 9-years.

The EGR + DPFE is probably good, it just probably a bad gasket or seal.
