Welcome to the forum!
Some backstory may help, why was the tcase and rear end replaced?

Check fuses.

Obd2 codes?

Obd2 codes?

I don't think 4x4 codes will be standard OBD2. OP will need to use ForScan for the expanded codes.

4x4 high light flashes for other reasons not related to 4x4... wheel speed sensor for instance will cause the 4 high light to flash, which would throw a code for a wheel speed sensor.

and I believe that would fall under ABS which not all OBDII devices read...

I used obd2 as a generalization. I'm fairly certain everyone understands what I'm talking about without further complicating things. I apologize if I have upset you.

Need the codes. Get it on a good scantool. And if you can get some live data check the front & rear shaft speeds while you are at it. Check the main electrical connector. Check related fuses (see manual).
