If you reverse a meter or so then forward again it goes off faster, or if you dont it will stay on but go out after a while

Do not drive on road surface in 4wd whether hubs are loked or in auto. You can change from 4 high to 2wd with no clutch while still moving. If in low stop. Can take a couple of mtrs for light to go out. But yes can help in reverse. On dirt tracks I would change to 4 around 50 klms and can change back withou stopping when get to. A hard surface

Sorry forgot to ask auto or manual transmission. Auto might be different

had the same problem with the (light) staying on - just a sticky switch in the transfer - replaced switch and light goes out as soon as 2h is selected.

cheers dassloth.

Hi, I'm new here and just registered to post an answer to this problem.
I had the same 4wd to 2wd light problem and in my case it was a 2minute fix.
Normally the light stays on if there is a short circuit somewhere in line from the 4wd switch on the gear box.
In my case the two probes where wires connected to the 4wd switch were touching each other.
Since you have overhauled the gear box this is possible because you could have accidentally knocked the rubber cover over the switch and that can bend the probs and make a short circuit.
Just pull the rubber cover out and check if this has happened.
If not start from the switch run along the wires and connections to inspect for any connection issues.
Good luck!

Welcome to the forum. Thanks for trying to help out another forum member but that thread is 7 years old and the OP has not been here in the last 6 years. It might be useful to someone else though.

i looked at the service manual, the switch is located on the left side of the transfer case. is there any alignment for this switch? I am going to take it out and have a check. somehow, back to Sydney, each time i shift from 4wd HI to 2wd, the led turned off straight away. but when i am at the snowing mountains ( may be at 2 degrees or below), the led wont turn off after shifting from 4wd to 2wd. I was wondering if something to do with the oil temperature inside the transfer case? I mean if it is too cold, then the oil is very thick, so the shift may not be smooth - or take longer time to disengage from 4wd to 2wd? but everytime from 2wd to 4wd, the led indicator lit up immediately regardless how cold it is..

I had a light that would not behave some years ago. My fix was to remove it and put a copper washer underneath it. This changed the activation point enough to sort the issue.

Thickness of the washer? Where did you put it?

It was a copper sump plug washer off something or other. I have a few spares. So it would have been a couple of mm thick like most of them are. I removed the sensor and placed it over the thread before re-installing. The sensor is mechanical, so the washer makes it sit further out from the casing.
