there is an SIB for it:

if the transfer case oil change doesnt fix it, replacement of the TC is indicated.

Thank you. I was aware of that. The purpose of my post was to encourage anyone that thinks there may be something wrong to get it fixed right away. Definitely before the 50K warranty expires.

Does a tune impact stress and strain on the transfer case? I don't even know what a TC does. Need to read up on it one of these days...

I would suspect so if you’re increasing torque.

A transfer case is responsible for distributing power from the engine to both the front and rear axles, as well as managing torque between them. Shocking to think they use the same one for all the different engines. My XB7 is 620hp at least 590tq. Not surprised it failed.

Ah ha, thanks for the input. I just installed a Race Chip GTS and would hate to put extra stress on an at risk component. Then again, I have none of the symptoms folks have been describing and I'm at 53k miles.
