Auto part Transmission part Metal Engine
Just hit 50k miles on my 2012 auto lx 4door. The shifts have been a little rough, so I decided it's time to change the ATF (automatic transmission fluid) even though Honda said it was fine at around 48k miles when I got my oil change. Got that gravel cover off and discovered this (imgur.com/a/J0BLa) Auto part Automotive wheel system Automotive tire
gunk all over the back side of the transmission across from the drain plug. I don't think it's my exhaust it was clean, rusty but not gunky. What do you think? Will Honda honor this under the 60k or 5 year warranty?

Probably not.
What can you expect?
Tech should clean the area in question.
Apply a white leak check powder.
Send you on your way for a few thousand miles.

If this were my car:
I would clean the area.
Remove the bolt viewed in the photo.
Clean the threads of the bolt, and threaded hole.
Then apply thread sealant rated for oil/hydraulic fluids.

Reinstall the bolt, torque to low end of spec.

The 1.8l engine does not have an oil pan gasket, per se.

And, in my experience, machined surfaces of Honda products, that are sealed with a liquid gasket, do not randomly leak.
When improperly sealed they will leak within a few minutes of running
Something smells to me; but Hey! At least the leak is fixed...
