The drain plug is softer metal than the pans capture nut.

Buy a new OEM drain plug and gasket (crush washer). Use a thread chase, to clean threads of capture nut.
Tip: By adding grease to threads of chase tool. You'll capture (most) metal practical in grease, that are cleaned from threads.

Toque new bolt to 13ft-lbf.

Check Transmission level, with a dip stick:
Drive a minimum of 20 minutes, shifting through all gears. Park on level ground, engine idling, shift through all gears slowly, holding in each at least 10 seconds. Shift to park or N, leaving engine idling. Check level.

BTW:
By looks of muck on bottom of your transmission pan, near drain bolt. It was removed before and not properly installed. Which indicates a flush or drain & fill was once done.

Parts store rent chase tool kits:

Sorry to dig up an old thread. And maybe @OwnerCS might have the answer...

What is the bolt size thread/pitch to tap the transmission pan drain on a 98-02 land cruiser/lx470?

Before replacing my transmission pan, I want to try this method of new drain bolt plus chasing the threads. Thank you!

You'll have your answer, by looking/measuring old and or new drain plug.

Old drain plug is pretty destroyed. But you are right, once I get a new one I'll figure it out. Thanks.
