Uh, Chris, you BAD BOY from Milwaukee, there ALREADY IS a note right at the top of the FAQs about opening the A/T. You suggested to the most recent sufferer:

"Never open that stupid plug again; they ALL strip out. Instead flush the
ATF with procedures that I'm guessing are outlined in the 700/900 FAQ."

And the FAQs suggest:

"Easy: just unscrew the tranny pan drain bolt, drain, and refill with the same quantity to the correct mark on the dipstick." [followed by directions]

Guess what follows? Guess who contributed it?

"[Response: Chris Herbst] Volvo no
longer recommends dropping the pan and cleaning the screen on the AW70 as a matter of routine maintenance, even though there is a strainer
in the transmission. Neither it nor the pan need to be cleaned unless major problems have arisen. This is from a recent Volvo Tech Service
Bulletin that dropped the recommendation, still found in most owner's manuals.
There should be a drain plug on your pan. Watch out putting it back in. The pan is very soft and I stripped the last one that I did. Also use a new
washer if possible."

Amen! I'd simply recommend much of it be placed in 24 point, bold, italic, flashing orange CAPS. ;-) Or something similar.

And/Or keep watching newbies stumble through, and, as my Catholic friends say, "offer it up."
