Tranny reliability

[Silver6spd]

How reliable are the stock trannies in the 6.4's with deletes, intake and fairly aggressive tune? Doin some stock class sled pulling and maybe an 1/8-1/4 mile runs boost launching..

if you go with innovative diesel's cutom tunning, the trans will hold 500hp no problem, when you put it to the big tune around 550hp, the trans will last a little while but be prepared to upgrade
