"Congrats! Those are fantastic rigs with a small trick to the shifter. To shift to 4low in the first gen you have to push down on the transfercase shift knob; for 4hi and 2wd you do not. It will fight you if you don't. You also have to be in neutral / stopped, it's not shift-on-the-fly like Jeeps and toyotas. When you disengage it you may also have to reverse for a few feet to get it to disengage properly."
YES my friend had a Pathfinder. Showed me how to put it in neutral and push down on transfer shift lever. she works. But I'm still learning how to get her out of 4WD low into 4WD high. I keep grinding gears. I have to shut of engine the put it into 4WD high. 4wd high to 2WD is easy. I guess I need practice. I have 240,00 miles. Do I put synthetic fluid in the transfer or dino fluid? Thanks
