B. Authorized Modification label
Part Number 04275086AB
1 - Label
C. Transmission Pump Kit (only if you pass the stupid noise test)
Part Number CECAF371

1 - Cover, Transmission front
1 - Filter, transmission pan sump

2 - "O" Ring, A/C line

Here is verbatim the procedure to qualify for Pump and all other goody replacement:
Section A. Vehicle Inspection
1. If the malfunction Indicator Lamp is set, retrieve the vehicle DTCs as follows:
a. Connect the CH9404 StarSCAN vehicle cable to the StarSCAN and the vehicle.
b. From the "Home" screen, select "System View".
c. Record all DTC's as shown.
2. Perform the torque converter test as follows:
a. Place the transmission selector in PARK (or NEUTRAL).
b. Apply the parking brakes.
c. Start the engine.
d. Step outside of the vehicle and listen for any unusual noise from the torque converter area.
3. Based on the results noted in Step 2, if the vehicle exhibits one or both of the following issues, continue to Section C - Transmission Flush, Torque Converter and Pump Replacement. Very few vehicles are expected to require this repair to be performed.
--> Malfunction Indicator Lamp (MIL) is illuminated with a DTC code of P0740.
--> The torque converter exhibits a rattle like noise in neutral or park.
4. If the vehicle exhibits neither of the issues listed in Step 3, continue with Section B - Torque Converter Replacement.
Gerald, my transmission and transfer case have been out so many times that I can repeat the process in my sleep.
Yes the transfer case will come out as well as the transmission. If the techs are not careful with removing the shafts, they will blow an input or output seal on the transfer case and then you will have to come back to have that replaced as transmission fluid will begin to form "tear drops" on the lowest bolt of the transfer case.
However, replacing the pump regardless of "noise test" results is the right thing to do. I'm sure you remember that the pump has been redesigned. If your techs at the dealership are hurting for work, then it will be advantageous for them to replace the pump because at least warranty work pays something rather than being idle.
The only reason that they would not want to replace this is if they had non-warranty work on their plate waiting for them with other customers as they get a higher rate for that work. Depending on your relationship with the techs this may be a non-issue and they may be intending replace the pump anyway.
If the pump is removed so will the clutch pack and you can have them inspect items such as the sun, ring and carrier gears along with the clutch plates.
I actually took days off work to witness this whole process under the hoist and in the service bay when my tranny went south.
