Re: Did Shudder TSB fix a problem?

the update seemed to reduce the shudder but not eliminate. however, i havent felt the rumble in sport mode. which is the only mode i use, for the most part. in auto you can feel it though, its nothing that would make me want to return the veh or not buy it in the first place.....but, im a jeep fanatic so......my opinion might be biased.

Re: Did Shudder TSB fix a problem?

Is shudder specific to all 4wd/engine combinations or only for some?

correct. at least thats how it reads. but then again, they had to update the original tsb to include the QT2.....so, things can change.

Re: Did Shudder TSB fix a problem?

What I don't understand is Jeep says how much real world testing the Grand Cherokee went through and that it won't be released until perfect. All that testing and this issue wasn't noticed before?

There's no amount of "real world" testing that will duplicate how thousands and thousands of actual owners will use their vehicles. Yes, I'd think this would have been noticed before, but there's no telling what issues have already been found and fixed before production started.

My wife said this exact same thing today. We had this TSB performed yesterday. It did not resolve the issue. It is less noticeable but still there in Sport mode and still just as noticeable in Auto mode.

Re: Did Shudder TSB fix a problem?

I have a 2007 4dr JK and it had the shudder prob. Mind was fixed by a new PCM, some by reprogramming the PCM, and others stated they had to get a new tranny to make it go away.
