steve_a Posted March 31, 2017 Share Posted March 31, 2017 Did you follow the correct filling procedure, it's an awkward one. Car level, filler plug out, fill till starts to come out. Start car and keep filling as someone moves through the gears until you get a dribble out. Next thing to check is the wiring, it can chafe around the rear of the transfer box. If the display shows the correct gear as you move through the box then the xyz switch is OK, assuming alignment is correct. After that you need to get the box diagnosed by something like nanocom and see if there are any clues. The other mechanical check is to put pressure gauges on the test ports and see if everything is correct. Use of pressure sensors and an oscilloscope appears to be a much better way of doing this though, with the ability to almost tell exactly what is wrong from the traces. https://www.youtube.com/watch?v=vM2eylbj4Go Quote Link to comment Share on other sites More sharing options...
