ABS
0x5A temporary system inactive
EAS
0x32 CAN bus fault
ECM engine (ME7.2)
0x48C elec thermostat circuit fault
IP Instrument pack
0xBD EBV function fault received from ABS ECU
LCM light control V12+
0x57 air suspension active/inactive
0x5A brake pad fault

A good set of seemingly random codes....

I don't think I'd be focussing on the transfer case neutral message as the key to all this. That is most likely just a symptom like many of the fault codes you have.

I'm trying to see what is common to that set of codes and my first thought is the ABS module or an earth point. I'm not sure how much more assistance I can offer from here though - it's nothing like the problem I have.

I have read the ABS module is known for a corrosion problem in the plug, so it might be worth disconnecting for inspection since it's a 2 minute job.

The tbox neutral was the first thing and it would lock in 5th gear and sports mode was disabled. From standing start taking off in 5th. Most times, turn off ignition wait a little while restart and all good for a while then it would all come back again.
ABS, EAS and yellow triangle appeared yesterday after I reconnected the batteries.

Did you turn the steering wheel lock to lock after reconnecting the battery? If not that will cause ABS fault codes and yellow triangle.

You need to clear all the codes are lock to lock. Then see what is remaining.

Good on me to forget that one.
Steering lock to lock done, GAP tool fitted read and all faults cleared. Reread and remaining faults.
IP- Instrument pack
0xBD EBV function fault received from ABS ECU.
LCM-light control v12+
0x5A Brake pad fault.
The brake pad fault is from new pads fitted and new pad sensor but the plastic housing on the car side of wiring harness was deteriorated and I'm try to fix it another way. Not sure how yet.

G'day All,
Is it usual for a gearbox rebuilt at around 230k ?
Cheers

That's about right for that box, they did have some problems. Fixes in place for the majority of gremlins; ( Sonnax Valve Kit ) it was a very widely used gearbox. Best to get a ZF specialist to do it, if possible as the clutch slip control system is so sensitive to unplanned clutch slip that it drops the transmission into failsafe the moment anything untoward happens. Not unexpected to see the friction rings in good nick; even at those K's.
