2001 Toyota Corolla Drained transmission fluid by mistake

Transmission problem
2001 Toyota Corolla 4 cyl Front Wheel Drive 101000 miles

I accidently drained the transmission fluid, and then over filled the oil spout with new oil.

Now oil dip stick is showing excess oil, while transmission dip stick is dry.

I suspect that now I have to drain all of the oil, and refill the transmission fluid.


Where is oil pan drain plug located?

Thank you.
