I've noticed some time ago that my transmission oil pan appears bent in the front and also seems to be a bit oily compared to the other sides. I am not sure if it was I or the previous owner who was offroading on HHR and hit something with transmission oil pan.

Transmission oil change was done around 60k and this issue was not reported by whoever was working on my car. Right now the car has 76k mi.



Is this something I should be concerned about?

 

Wipe it clean and monitor for leaks. If you dont have any issues with tranny or any leaking dont worry about it!

 

Could the oily fluid be what is going on your catalytic converter!! wild is the wind!

 

I guess the best way to find the source of this is to look for any traces of under the car along the exhaust pipe. If this is the source, then it has to get down to the catalytic converter somehow!

The engine block is spotless.

 

If the ATF is onlw weeping not dripping, I would not worry about it until it's time to change again. New pans cost less than $60.

I posted in your other thread that I believe you are mixing up the muffler and the catcon.
