INFINITE!!!
Seriously.. You aren't beating the crap out of it on launches and 1-2 shifts as is done with an AWD trans, but if you try that type of stuff it will blow up even under stock power due to wheel hop.

If you are already moving and you give it too much power, the wheels will break loose before the tranny blows up. Just let off when you lose traction.

Disclaimer: This was a general comparison between AWD and FWD trans. I don't know if the 2G FWD trans has a particular weakness.
