The only way to get rid of the vibration is get rid of the vehicle, and don't get another Chrysler product. Read back in this chain, that's the main theme. It's not the tires.

There was a TBS for a ECM Flash to improve Torque converter operations. Does anyone know what this actually does:
Bulletin Number: 2101105
NAG1 (W5A580) TRANSMISSION - SHUDDER WHEN TORQUE CONVERTER CLUTCH ENGAGES. *TT
 
Bulletin Number: 06002
FLASH TCM AND ECM TO IMPROVE TORQUE CONVERTER OPERATION. *TT

I guess that Jeep has had a problem with this for some time. My dealer has said that he has replaced TC in the past for this problem. It describes the problem I'm having with my 2008GC exactly! Maybe Chrysler will own up to the problem and come out with a real fix.
I don't think I'll keep mine that long...Its gone in the Spring!

I just spent $3000 to get it fixed, low and behold, replacing the torque converter did not fix the problem.

Jeep Grand Cherokee Limited Hemi Vibration by youngmoney

I'm in my 5th month of a 27 month lease. Can't wait to get out of this lease. I got a 2007 Grand Cherokee Limited with the Hemi and Quadra-Drive II, $39.960. Right now I have about 7500 miles. All I can say, Chrysler does not know how to build a car. I haven't had this many problems with a car. Over the last five years I have driven an Envoy and a Yukon Denali, and so far the Jeep has been to service more than both of those cars combined, and all in 5 months. It's sad, because this can be a really good car. Some things I like about my Jeep, is the handling and the brakes, the Hemi engine, and the features like Remote Start and RainSense wipers. The rest of the car is trash. It has a throttle delay, and just today I felt the vibration. I was going about 70-75, on cruise control. It wasn't that bad, it felt like the strips at the side of the road that warn you when you are at the edge of the road, but it was annoying, especially at 7500 miles. God Bless Chrysler, because if they are expecting to be profitable like they have been talking about, they have to get rid of these problems. I have a Commander U pkg also and that has a much smoother ride than the Grand Cherokee. The only problem with the Commander is the windshield that cracks every winter. The only things that really make me want to keep the Grand Cherokee is the power and handling, and the dirt cheap price I got.

I also forgot to mention the clicking sound I got, when I drove over a small bump in the road. If I remember correctly that happened at around 1000 miles. Sounded like a parking cone was stuck under it.

Hi all, I took my GC '06 in with the "rumble strip" problem. They replaced the TC and some various transmission seals, etc. It cost $3000.
 
I'm am trying to put together a case that Jeep knows of the problem and has no fix for it, so the Jeep delaership (who performed the repairs) really did not have to replace the TC.
 
My point is that Jeep knows the problem, it's a fairly common problem and I honestly want my money back because the problem is still there. I want to go to the owner of the dealership provide him of the evidence that this is a common problem with no known fix and ask for my money back.
 
Can anyone point to a resource or someone to talk to get more cases of where Jeep has acknowledged the problem and has said in public that they have no fix for it?
 
Several people on the board mentioned some engineers they have spoken with, is there anything out there in the public about Jeep talking about this issue?
 
I did find this link that might be of interest with a few suggestions of a fix. You need to read further down:

Any help would be appreciated.
 
Thanks

Hello Youngmoney 1/18/2008
I had a meeting with the service manager at Dover Dodge and the regional manager with Chrysler on Wed 1/16/2008. We all when for a highway ride 60-78 MPH.
I told the rep about the problem with the Goodyear fortera HL OWL tire balance problem. 1 Wheel was found to be out of balance they removed that right rear tire and put the spare tire on the Jeep, the vibration did decrease, however I said I was still not 100% happy. The Chrysler rep asked what I would like. I said I want all new tires on the car since those Fortera's seem to be the problem since all the wheels had 2-3 oz of weights on each one. I wanted Michelin Cross Terrain SUV tires.
Friday 1/18/2008 I took the Jeep back to the dealer, they installed the 4 new
Michelin tires, I took it for a 25 mile highway ride. Results are NO VIBRATION at all. much quieter and smother ride. Less than 1 oz weight on all the wheels
My advise to all jeep owners with Fortera tires, tell the dealer they want all new tires and not Goodyear, they must be having a Badyear making good tires.

Hello to all,
 
This thread applies to a driveline vibration on '07 and '08 Grand Cherokee's that ONLY occurs at speeds between 65-80 MPH and has to do with the drivetrain. More specifically, the driveshafts. Most have the Hemi engine. It is NOT about other year vehicles or crankcase problems. Please start a different thread for earlier year vehicles as we are getting a bit off the path of the original posts.
 
Thanks to all,
Alan
