Hi everyone, I was underneath my Buick Lucerne the other day and noticed leaking ATF fluid. I noticed the area around the axel seal is wet and dirty. Anything to the left of the seal isn’t wet with fluid at all, But the CV axel and seal are wet with fluid for sure. Would I be correct in assuming that I need to replace my CV axel seal ? Just want to make sure before I tear this car apart or take it in to get it replaced. I have attached pictures below, Thanks !

I don’t know much about the transmission that is paired with the series III 3800 V6. I would assume it has fluid.

The trans-axle has transmission fluid both in the transmission and differential.
