Tranny Drain Plug Stripped
good luck with the repairs bro
Go to the auto parts stores and look for an oversize self tapping plug with an o-ring sealing center drain bolt that comes out. I found them at Auto Zone and Pep Boys both. I bought several sizes after eye-balling the original plug against them (stated size seems to be variable) and after trying several, found the one that fit the best.
I don't have one of the gold scissor jacks folks use on bike lifts so I took the wheels off my regular floor lift (the one you can pull around like a floor jack), slid it under my bike while on the big lift and jacked it up about 12-16", locked down the jack and tied down the bike. This gave me lots of room to get up under it and screw the thing in straight this time.
I threaded the tapping base in slowly, backing out several times after about 1.5 to 2 threads were cut, cleaned it off, cleaned the threads off, etc. until I'd tapped it all the way to a seated point. Then I poured kerosene through the filler hole to wash it out, did it a second time with a 1/4 quart of oil mixed with the kerosene 50-50, and then blew it out with high pressure air from the top. Finally just stuck my finger in and worked it around to be sure I could feel no other thread shards.
After that, it was a matter of screwing the whole thing in and torquing to spec, and filling with trans fluid. No problems in 10k miles and no leaks.
Hope this helps.
