Wife was complaining about s rattle noise under her rig, 03. Checked it out, broken exhaust pipe at muffler. Took it to work, threw it on the hoist, cleaned up pipe and welded her back in place. Just like new.
Now, when she said she heard a rattle...l didn't give her the same response I usually give the drivers at work...when they complain about hearing a rattle.
Conversation usually goes like this..."Brian, I hear a rattling noise while driving."
Me, "Do you hear the rattling noise more on the outside of your head or the inside?"
It's even funnier, when they actually stop and think about it for a moment...and eventually say..."l'd say it's more on the outside."

From D2 WM:
Todd,
Are you having trans specific issues/symptoms? If so there appears to be some other components you can shotgun or check the CAN bus wiring/connectors.
If you take the time to look up codes in the D2 manual you might save some time/money and learn some things. LR did a decent job of providing their descriptions for the D2 relevant codes. Descriptions most code readers spit out are almost as useless as the generic code lists found on the web.
......
The CAN system is used by the EAT ECU and the ECM for transmission of the following information:
l Gearshift torque control information.
l EAT OBD information.
l MIL request.
l Vehicle speed signal.
l Engine temperature.
l Engine torque and speed.
l Gear selected.
l Gear change information.
l Altitude adaptation factor
l Air intake temperature
l Throttle angle / pedal position
Function
The CAN system uses a twisted pair of wires to form the 'data bus' to minimise electrical interference. This method of
serial interface is very reliable and very fast. The information messages are structured so that each of the receivers
(ECM or EAT ECU) is able to interpret and react to the messages sent.
The CAN 'data bus' is directly connected between pin 36 of connector C0637 of the ECM and pin 16 of connector
C0193 at the EAT ECU, and pin 37 of connector C0637 of the ECM and pin 44 of connector C0193 at the EAT ECU.
The CAN system can fail in the following ways:
l CAN data bus wiring open circuit.
l CAN data bus wiring short circuit.
In the event of a CAN data bus failure any of the following symptoms may be observed:
l MIL illuminated after 2 drive cycles (NAS only).
l EAT defaults to 3rd gear only.
l Harsh gearshifts.
l 'Sport' and 'manual' lights flash alternately.
P0600 - Serial communication link malfunction - CAN time out
l Gearshift torque control information.
l EAT OBD information.
l MIL request.
l Vehicle speed signal.
l Engine temperature.
l Engine torque and speed.
l Gear selected.
l Gear change information.
l Altitude adaptation factor
l Air intake temperature
l Throttle angle / pedal position
