2011 MDX Transmission leaking?! (26K mi)

One month ago, I found out lots of oil on the floor of our garage.
Last week, we brought 11 MDX to dear then they said side cover was leaking and replaced with two O-ring (91318-RT4-003, 91317-RT4-003, and Hondabond). However, I checked several times this week, it is still leaking

(please see "pic01", "pic02")

I original think it is leaking from where they said, the left covers.

; however , I did open hood and see there are red oil accumulated on left top of transmission ("pic03". the red arrow)



I wiped them out with paper towels("pic04"), yesterday.

and drove one or two miles then checked again. They are there.

I whiped them out today, and drove several miles and checked,
unfortunately, they(red oil) want to stay there.

See video link below ( it is very difficult to shoot this video, sorry for bad qaulity).

Did anyone have the same problem before? Where is the possible leaking point?

Many thanks

Dealer held car for 4 days, and just got car back, will drive a few days to know if the leaking is still there.

That looks like the trans range sensor. It might need a new O-Ring so its all good easy to replace.
