i havent seen any other posts of this nature, so just thought i would put this out there. My CRD began bucking and shuddering at low speed last week. i took it into the dealer the next day, they replaced a seal or something that was blocking fluid flow and locking up the torque converter. That still didnt fix the problem, so they performed the software flash that i read about on this board. Still didnt fix the problem, so DC asked them to totally tear down the tranny, and if it needs more than 60% of the internals replaced, i will be getting a completely new unit. From what the technician said, it seems likely that i will get the new transmission. He also seemed amazed that it went bad, as it is the same tranny as in the Grand Cherokee, and he has never had to replace one. Glad we bought the better warranty, this is our only vehicle. Not a problem though, since they had Enterprise hook us up with a fully optioned '06 Grand Cherokee while our CRD is out of commission. We would feel guilty owning something like it, but the leather seats and sunroof are kinda nice. One final note, it is surprising, but the Libby actually has more headroom! I am 6'4", and fit fine in the Libby, but bump my head in the Grand if i dont tilt the seat way back. Wierd.
Disclaimer: I am not posting this to complain, just to see if others have had any similar problems. Knock on wood, my service department has been great to work with.
