Mine started having that issue and brought it in and the dealer replace the clutch pack and the issue has disappeared but I only rode it for about 15 miles, will know for sure tomorrow since I'll be doing a long distance drive tomorrow but as for the shuttering during turning, it's now gone. They were going to charge me $900.00 but since it was still under warranty, it only cost me $100 (deductible).

 

Put another bottle of friction modifier in it. I had to put two bottles in my 2000 TL 9.75" rear to get the clutches to work smoothly. It all depends on how tight the clutches are shimmed. The 2000 models were set up tight and there was a TSB on the subject.

 

The parts came in. I took it in this week and it's done. As of now the vibration is gone, i've got about 100 miles on after the install. Let me know if you need part numbers or details.

 

Hey, I am having the same issue.

Ssamme-please let me know part numbers and more details in case the fluid change does not work, how much $$?

thanks!

 

I can't give you a price on parts because the truck is still under warranty. They did not replace the clutch packs entirely but did add a spacer.
