I may have posted this question in the wrong place yesterdayso i'll try again.
bought a 2010 Grand Cherokee Hemi back in Oct. by Dec.(70,000mi) it started shuttering when the excelerator was held at the point that was needed to just maintain the speed worse if on an uphill grade useually a light vibration but on occasion like a flat tire or hitting the rumble stip on the side of the road(enough to be felt in the pass. seat). the dealer has replaced the torque converter twice and added Shutter Guard. this has reduced the frequency of occurances but not eleminated them. said all computer codes looked good does'nt look like they know where else to look.
anyone here have any thoughts whats wrong, we like this jeep don't want to trade it back in
Thanks for the help
