Transmission is good for sub 400 ft lb of torque per spec but can be upgraded to ZF8HP70. You currently have the zf8hp50 or zf8hp51.

I haven't seen any of the high HP guys upgrading their transmission. Pretty sure I only seen one guy upgrade his with a 8 speed from a diesel F30 because his trans failed and dealer wouldn't cover it.
