Hello Guys



I hope this message finds you well.
I just finished changing the engine oil in my 2017 Trailblazer Automatic Tranmission with about 115,000 KM on the Odo.
Other than minor hiccups such as lose airflow hoses which made the vehicle to go limp, otherwise she's served me well.



Whil exploring under the hood, I saw the follow picture



1. It was oily by the touch, and the color is black
2. I do not see any visible drips on the floor, therefore I assume this are moist and related to tranmission or coolant lines (honestly, I am assuming the two lines are from the coolant)

3. I have checked the level of trans-fluid throug the fill-hole , it was about the right measurement and the color of the fluid is towards light brown - red (I did a drop and fill of the trans fluid less than a year ago).



I was wondering , has anyone experienced this? What are the steps taken to have this fixed?
I actually can "ignore" it and just drive as per normal, but I would like to have this resolve or possibly know if there's anything I need to change to prevent further damage, if any.
And also, how much effort will it be if I decide to have this fixed? Will I be replacing a gasket or do I need to unfill all the transfluid..etc?



Appreciate your inputs..



Thanks alot

 

 

I don't think I would worry too much unless it got worse
