"I was told there are two models of torque converters available for use in our Jeeps, an old one and a new one. The old one was ordered and placed in my vehicle, it won't fix the problem because the new one is the fix. My dealer was told by Chrysler that the official fix for the shudder is to replace the torque converter with the newer model. But the new torque converter is not available at this time. Why you ask? Great question.........

Answer: Because it has not gone into production and it may be a month before it does.

So basically I have to drive the Jeep, with the shudder, and now an occasional clunk until they make the part to fix my Jeep. I can not even trade this one in if I wanted to get rid of it, because no dealer in their right mind is going to take it. "
======================

Well I have what I would call a clunk at about 42 mph when I give it slight accel. Not WOT. I would not call it shudder. It sounds like the trans (or torque converter) is having problems doing wat it needs to do.

5.7 Hemi, 950 miles

Clunk might be a good way to describe what I feel too-
I don't think it's a shudder - from what I read I would know if I had a shudder-
but when I drive on the highway between 50-65mph and either give very slight pressure on the accelerator or just cruise, or slow down by lifting off the pedal slightly I get some feedback from the car - I feel in it the steering wheel and I think a clunk is a perfect description.
Didn't really notice it until I had to drive for 4 hours at first I was curious, then it got annoying.

i have the exact same issue. 5.7 4x4. It appears to happen when i let the car roll forward under torque converter power only, then accelerate. The speed seems to have less to do with it than the RPM.Odd that it seems to happen less in sport mode, but that could be me altering my driving style as well.




there was a similar discussion in this thread: (not sure if its the same issue) http://www.jeepgarage.org/showthread.php?t=23850
