I am new dodge ram owner. I have had it for 3 weeks now.. I must say I love it..I did buy it used with 24 k on it. It is a 2011 5.7 crew cab. Not sure which rear end... It came with a after market exhaust which is the only mod. I have noticed I am displeased with the way it shift around town. It is in gear and out sometimes it feels like it is struggling.. I have been using the tow haul and it is a little better..I don't have any of the sound issues.. Sometimes when I drive around a corner it lugs like it doesn't want to go..then I step on hit slams down a gear goes... I have heard good and bad about flashes...and the torque converter.. I want to bring it in but can't be with out a vehicle for a long time..vi would like everyone's personal opinion? Bring it in? Or am I just a MDS victim?
