I recently had my truck flashed with the long crank TSB and now it idles at around 800 rpm. Since then the whole truck has a vibration at idle that really is noticeable in the gear shifter, as well as a vibration when I let the clutch out when getting the truck rolling. I was wondering if this is a sign that the dual mass flywheel is on its way out??? Drivetrain is stock with approx. 15000 miles.

 

maybe your getting a lazy injector?? is it smoking?? I have noticed mine has a intermittent rough idle... while it rough idles it smokes some small amounts of white smoke but it is really small so I have just been watching it..
I was leaning more to injector then the clutch??
but I don't know..
BTw it also happen while warm so it not just a cold diesel

 

There's a TSB for 'Gearshift vibration at Idle' for trucks built before 1-18-05 that calls for replacing the dual-mass flywheel but for an '06 ? ? ?

Thanks MJ, I'll try that TSB with the dealer.
53....no smoke and it'll vibrate both when warm and cold, but still could be a "lazy" injector. I'll make an appointment with the dealer and see what they say.
