Cheers for the infoA friend of mine had the same issue. Checked micro switches by gearlever. There are 3 of them. If they are tested and working fine your other option is to get a complete cluster. Gauges and all. That was the only thing that solved his problem. He got a cluster which had 2000km less on than his original
I have only noticed it during normal driving, only because I do more of that than offroad. Just last weekend coming back from Oberon and going up the steep hill along the Great Western Hwy when leaving Lithgow, I thought I would play around with the manual shift mode, and nothing happened. Tried it the next day and it worked?It does depend on WHEN you're having the issue. This might not be your situation, but just in case it is ...
We noticed that the gearbox doesn't behave properly in 4LO - during some steep descents into creeks in 4LO, the car would pop out of first and into second, reducing the engine braking and requiring more foot braking. In 4HI and 2HI it never does this - manual mode stays strictly "manual". It's only in 4LO that the gearbox ignores the setting.
One user here (Raptorthumper, if memory serves) found a solution to the problem, although it's not ideal for everybody. Disconnect the servo plug from the back of the transfer case, and connect it to a switch which allows you to apply momentary power. 1 second of power will turn the servo 90 degrees or change the transfer case from 2WD to 4WD. A further 2 seconds of power applied would turn the servo a further 180 degrees, changing the ratio in the transfer case thus engaging 4LO. Done this way, the gearbox and the car's ECU have no idea at all that the gearbox has been manipulated and manual mode works as expected.
