My '05 has a strange issue. When going downhill at 60-70mph either on cruise or without it, when I go downhill I get this studdering that I cannot figure out. I have bled the air out of the filter and that didn't help and it does not have any power loss or running issues otherwise. It did it once or twice on a straight road and a few times going uphill, but it seems most noticable going downhill. My first thought was the torque converter going in and out of lockup. Any ideas? I know if I go to the dealer, they won't be able to duplicate the issue and I want to find out if I should be worried or ignore it. Thanks!
This is the infamous CRD "shudder". It happens when you apply more than normal throttle (accelerating on an on-ramp, going up a hill, passing traffic) and then back off the throttle. It can happen with cruise control too, in the scenario you describe. This throttle lift causes the drivetrain to stumble. Nearly everyone's seems to do it, it is not fixed by F37, and it is just about impossible to get a dealership to do anything about it or even acknowledge it. It's the only remaining wart on our 2006 CRD experience, and it's annoying because I'm sure it's a fixable thing if Jeep only cared enough to solve it.
Doing a search on "CRD stutter" or "CRD studder" or "CRD stumble" in this forum and at jeepforums.com should provide you with some more interesting reading.
