ATF Leak

First post. Use this great site daily for information and ideas. Thank you for everyone who contributes.

I just finished replacing my rear output shaft seal (32RH to NP231), which fixed that leak. However, I have now noticed a few drops of ATF leaking at the front, driver's side of the transmission. Any ideas as to what the cause could be? Main seal?

Let me know if more photos would be helpful. And thanks for any and all help.

For some reaeon I cannot see the photos but check your power steering reservoir. Mine was overfilled from the dealer the day I bought it and trickled down the pipe from the reservoir.

Added links for photos. Hope those worked.

And thank you for the quick response and advice.

This looked like the same ATF fluid that had been leaking prior to the output shaft seal replacement, when looking at it on pavement.

But now that I've climbed up in there.... it's motor oil

And coming from a big circle

That is a freeze plug. It holds back antifreeze. If it is really leaking, it will eventually go and drain the engine real quick and it will overheat NOW. But you think it is motor oil? Clean it off with some cleaner, any degreaser and keep an eye on it and tell us what you find.
