It's not the HP that tears up trannys it's the Tq, plenty of Rotary racers here use W's at insane hp levels but they don't produce much in the way of tq so they get away with it.
7M + carefully built W58 + gt3040r @ 9psi and it started showing signs of stress so I retired it before it took a dump.
Typically high mileage boxes have worn through the hardening on the nose of the mainshaft where the needle roller inside the input shaft lives (Foot off the clutch at lights idle grumble is a good indicator of this)
