What is leaking here?

Much appreciated if you can tell me what my new leak is....

 

That’s the Check/Overflow plug for the Automatic Transmission.

 

Yep. Did you or a shop check the fluid level recently? Either needs a slight bit more torque or a new crush washer.

I'd snug it just a wee bit and clean the area with brake cleaner and see if it continues to seep. Not a problem leak though.

 

thanks - I JUST had an aftermarket trans cooler installed friday.... so yep that seems to be the issue at hand now...

It's not an issue, just make sure it's snug. Be careful that you don't over-tighten it, those threads are tiny. use one finger on a ratchet handle and see if there's a little bit more room to turn. If it seems snug then just clean it up and monitor it

 

that’s normal. With the added cooler, the installer would have added atf fluid. This is the check plug where they verified appropriate fluid level. Totally normal given the circumstances. Only thing you could check is make sure that drain plug is snug.

 

The correct answer is, nothing is leaking.
