I noticed there was a drop of trans fluid right underneath where the radiator trans lines would normally attach (I have an aftermarket trans cooler). I could turn the "plug" with my fingers so I got out the appropriate 10 pt socket but it would just turn and turn and not tighten. The one on the other side does the same thing but at least does not leak...yet. Looks like I will replace these plugs but I was curious if anybody else have seen such units???
