I have a 2006 GX470 and the 4wd system has been giving me some problems lately. The car will only drive in "D" when I have the transfer case in either low or high...Other than that when I have the transfer case in neutral and I try putting it in "D" on the shifter its the same as neutral and also when I put it in "P" its still in neutral and will roll back if I don't have my foot on the brake. Long story short...How can I just drive the thing normally again with the shifter in Drive and the transfer case in neutral like I've always been able to do! Thanks.

To drive the car normally the transfer case is in H and the transmission is in D. Neutral is alway neutral, which mean it is not in gear.

Shift your transfer case back to high and go on your merry way. The neutral in the transfer case is for when you are being tow.
