im going to do this as soon as it cools off some, i was hoping the dealership would get them changed out if i complained enough. im taking my truck back to the dealership every oil change to complain about the leaf springs and this horrible 8psd transmission. other than those two hunks of chit i like my truck. i wish i would have ordered a 6.2 and 10 spd but ill run this one until its almost out of warranty and trade it in. maybe by then they will figure something out. I loved my 2008 Seirra Denali 270,000 trouble free miles, so im not ready to give up on GM yet because the other trucks are fugly compared to the GM trucks...yet
