yes, those engine that are over 300hp or so will eat a stock trans in a few thousand miles if you dont have a good amount of torque management still in the calibration.
Even the 4l70 will get eaten by 400hp and 4200 lbs without torque management. A shift kit and quality clutches with a little extra line pressure is a minumum.
I'm curious to see if I can tear up my th400 that killer b built.
it's getting replaced with a 4l60-70 of some sort when it does crap out so I need to get at least a year otu of it....
