I noticed on Saturday when I was changing brakes on my 2006 S60R that there was couple drops of trans fluid on the floor could not find where it is coming from. Does anyone have an idea where to begin to look?

 

Welcome to the forum Markemark

Moved your post to the S60 section where hopefully you will get some help.

You can try putting some clean cardboard under the car when you park for the night and then use that to better locate the area it's coming from.
Common areas would be the connections at the transmission and at the radiator for the trans cooler hoses.
