So is this the Shudder that some of us experience?

This is a pretty extensive TSB:

Quote:
This bulletin involves the replacement to the transmission torque converter, pump, filters,
and oil cooler.


I wonder what the root of the problem is. And why the cooler is replaced, is it part of the problem or collateral damage from the root cause.

It all goes back to the wrong filter being used and not replaced soon enough, whether by owner not knowing or noticing till too late or dealers refusing do the TSB as soon as possible. As the torque converter sheds small pieces they migrate to other parts of the tranny.

This TSB describes exactly what the dealer is doing to my CRD. They have had it for over a week, and supposedly are waiting for the torque converter to show up. This must be a hot-off-the-presses TSB, i hadnt even heard of it last week. They tried the filter and flash first, but it didn't fix the problem. Hopefully the new TC will last a LOT longer than the first one did!

Well, i FINALLY got my CRD back this afternoon. Ran fine until getting off the highway after picking my wife up. All of a sudden, it decided not to shift past 2nd gear unless revved way past where it should normally shift. So we limped home, and will be seeing the service guys again as soon as they open up in the morning. Needless to say, neither of us is going to be pleased about the fact that it took a whole 3 hours before our transmission learned a new way to be a PITA!!! :x Also, i crawled underneath the Jeep as soon as i got it home, i think they are blowing smoke about replacing my cooler. Either that, or it is tucked up above the engine skid where i cant see it.

Did you ever get resolution to this? I am starting to get the dreaded shudder and wonder if I should try and get the dealer to replace the torque converter before it completely implodes, or just wait and see what happens, if anything.

I had similar shudder and frequent shifting problems with by 06 Liberty Gas at 7,500 miles. The dealer had to replace the torque converter and transmission pump. So far so good.....

I have noticed a rattle at idle while in gear for a while now and thought nothing of it until I read this post. I had the recall performed to fix the torque converter lockup problem associated with the highway shudder, but I still hear and somewhat feel the rattle/shudder at idle while in gear.

Also, I also feel like the one/some of the engine mounts might be worn out. When I throttle up or down, in gear, it feels like the engine is shifting on it's mounts. Anybody experience similar problems?

Thanks,
Steve
