How often are you getting the codes?
It was rare. Then, the other day it popped up on my way to work. So, I changed fluid in transfer case and front and rear differentials. After I changed fluids, it was gone. But, then yesterday I was in town doing errands, and it popped up yet again. I have noticed that it's getting harder to put gear shifter in Park.
