Engine/Transmission (1998.5 - 2002) Trans up-grages ?

[CMaster]

Hay folks, just got my Banks system installed and think I have problems. If I get on it pretty hard the whole truck shakes ( feels just like a bad spark plug under a heavy load ) and the truck sets a Crank sensor code. Banks tells me that the trans. slip protection the is buildt into thier system cut the fuel delivery during trans slip, not engine shutdown. Does anyone know about what it would cost to have the transmission beefed up to handle the new and exciteing horses? Automatic transmission by the way.
