Hope this helps...

Thanks happy that i actually have the original transmission and the thought had crossed my mind to reinstall it, thanks to Graeme tugging a thought line i managed to get it to engage and function, worked perfect for 600 meters then get a transmission fault of 0xF000 U3000 Control module, so maybe wrong but think it maybe due to the replacement transmission.

original issue was the transfer box was in neutral, a scan through the service manual gave a calibration procedure of depress accelerator to the floor insert key turn till dash light illuminate without starting, press and hold high range until you hear it engage or longer than 5 seconds turn off key release accelerator, wait 15 seconds insert key start car and select low range.

worked a treat.

cheers

I wan't aware that there is a driver procedure to re-calibrate the high-low range change - thanks!
