Transfer Box neutral - High Range then Trans Failure on 2004 Land Rover Range Rover

My repair shop (not the dealer) thinks it is a sensor but cannot figure out which one it is. Mine has switched into 4th gear on the highway upon these error codes.

if your shop can't figure this out, you have the wrong shop. you need to look for a specialty shop that has the
Land Rover software to diagnose this problem correctly.
