A few minor issues while chang'n the trans fluid today, so look'n for suggestions

some of today’s cars just use sealant on the trans pans. If some gets inside, the filter will catch it.
Oversize bolt and a tap will fix the stripped bolt. Refrain from using power tools. Dont have a torque spec, but it isnt much.
Like all you can do with a nut driver.

I like to contact cement gasket to the pan. Thats all i use for sealant.
