there is a lot of talk on this forum about the stock trans ratings... has anyone actually proven how much the trans can handle? im about to run the zzp stage 2 and just wondering

 

240 Hp

 

Hahn has run well in excess of 400hp through the F23.

 

are we talking F23 or 4t45e?
or, if you dont know the difference, are you manual or automatic?
Regardless, both trans can take a LOT of power. The manual just needs a better clutch, and the auto needs a tune and a trans cooler.

 

Your trans is fine. The lap internals (motor) will blow long before your reach the danger zone with the trans.
