Just to let everyone who doesnt already know. There is a old tsb (11-7-10) on the 2011 trucks that has to do with shift flares and irratic shifts and other issues. Well its hard to find all the info i needed, so i went out on a limb and dropped my pan and got the band numbers off the three high pressure solenoids and changed them with the new ones. I was worried i would have to get the pcm and tcm reflashed as stated in the tsb. But since my mini max is up to date, i did not have to get it reprogramed. I have only put around 20 miles on it so far. But the shifting is great so far. It seems to shift right on time and it seems firmer. So far no flares or irratic shifts and it normally would of. So to anyone with a early eleven, i would recommend doing this if your tired of the way the truck shifts.
