XC70 Part ID? - Resolved
2007 2.5 T
As I was reaching down to the transmission dipstick, I noticed a little yellow plastic (I think) thing on top of the transmission housing that looks like a cap of some sort. It was loose, but wouldn't come off and I didn't want to force it. Didn't feel threaded. It was only about 5mm in diameter. Any ideas what it might be?
