On the shift on it own do you mean it shifts itself in and out or just does not want to shift?
What does the shift button lights do when you try to shift it?
Have you tried shifting in neutral or when it is rolling back or forward?
Are your tires a matched set and rear ends match up?
Is the front actuator getting good vacuum?
Does it lock in front axle good?

It shifts on it's own without me touching it. when I try to shift the light on the switch flashes & hear the click in the TCCM but it doesn't shift. No I haven't tried shifting in Neutral or while rolling backwards. This problem general shows up very randomly. I will be driving down the road and see the 4wd lights flashing out of the corner of my eye and all of a sudden it is in 4wdhi. I push the button to get it back into 2wd the lights flash I hear the tccm click but it stays in 4wd hi. Then at some point it shifts back into 2wd on it own...
I have not checked the actuator yet or the codes, I will do that this weekend. if I have to take the battery & tray out to get to it how do I get the car running to test it? Tires are good and matched. when it locks into 4wd it locks good.
