Still planning on updating this with some pics/info in the future. Had been waiting to get an ICOM so I could properly go through the test plan and reset the mileage counter. You absolutely MUST use an ICOM to do this. Neither the Foxwell or ISTA w/ K+D CAN cable could perform this. Both failed. After getting the ICOM I had the car up and running within 10 minutes. Went through one test drive cycle and the car still drives and shifts great so the trans work on this truck should be done.

Ran through the 50 minute test plan in ISTA a second time and it indicated new NOX sensors were needed. I assumed it would. New sensors are here now. I ordered them off ebay and they are touted to be genuine but I have my doubts @ $340 for the pair. Before installing I confirmed with seller (still have my doubts) they are genuine so I can install them. If I run into problems I'll file a case and get $$$ back.

That's where I'm sitting at now. Will update when progress is made.
