Well, I replaced the encoder sensor ring, that didn't fix the problem. I just checked the fluid level, it was seeping out the fill hole, so it is full. Color is not blue, just a little bit off clear. Interestingly, as I turned the bolt, I heard a clicking sound that started and stopped a couple of times.

It now wants to jump into Auto4 every time I start it. I have to hold down the 2WD button until well after the startup lights clear before it will settle into 2.

I was able to get the codes scanned and it showed C0306 - Motor A/B Circuit Malfunction, and C0379 - Front Axle Circuit Malfunction.

The history codes showed C0306, C0359, C0374, C0379, C0550, B0790, B2725, U1301. Would be nice if they stored dates with the codes.

I'm thinking replace the encoder motor is the next step? (I've replaced switch, cleaned grounds, replaced encoder sensor)
