Howdy all. Have owned a 2010 1.8L for about six years now. Lurked for a while but since the car has never given me a single issue in that time, I've never needed to post.
It was finally time for a partial transmission fluid swap, so I did it along with my regular oil change last week. Managed to drain and replace just about 3 quarts. Everything went smoothly and the car has been running great.
However, I've been having a very slow transmission fluid leak since the change—four days now. I completely wiped down the pan and around the plug after the swap, so I know it's not just residual mess dripping off the outside of of the pan. Plug is tightened down pretty snug.
I didn't see any type of gasket or crush washer on the plug or pan when I pulled it. Is there normally one? Any other suggestions?
Thanks!
