'08 Megacab with the usual deletes and a XRT Pro. Bought the tansmission software as well. Running the engine on tow and transmission all on the standard settings as this is just a daily driver, grocery getter. Every once in a while when slowing down to a light I am getting a tranny "shudder" that seems to jerk the whole truck. Just had to rebuild the tranny, from the previous owners abuse. Just don't want to have to do it again. Any other people notice this same thing happening?? Thanks
