2009 VNL730 D13 IShift Stealers trying to force a new trans down my throat

This all started two weeks ago.
Truck derated and had a boatload of NOX codes.
I write the codes down, clear them out and drive to dealer.
They replace NOX and exhaust temp sensors and flash the ECM.$1855
I head out of the shop on day three only to derate and get a code for the exhaust temp sensor.
Write the codes down, clear them out and drive to dealer.
They spend 5 hours sitting in my truck and the end result is reload the software updates.
I head out the next morning only to have the transmission stop shifting right and putting me on the side of the road.
I write the codes, only trans codes, clear them out and drive to dealer.
Here are the codes:
MID 130 PSID 25 FMI 0
MID 130 PSID 25 FMI 2
MID 130 PSID 25 FMI 7
They want to drop the trans and have quoted me between $15,000 and $17,000
I could really use some help. These "techs" only know how to read check lists and step 5 is drop trans!
When you clear the codes it's fine. HELP!!!

 

I'm at a small shop to have them go over the work done by Volvo. I'll post when we find something.

 

Today they installed a new ABS/TC computer and nothing changed!
