Re: np203 stuck in 4X4

just something to try next time if you can try shutting off the truck and seeing if it will i asked my dad who's been in trannies/4wd etc for too many years and he said mine would go into 2wd if i shut if off because there's no pressure on it so naturally i argued with him saying that makes no sense, tried it and felt like an idiot because it worked perfect just a thought because mine doesn't always like going into 2wd

Re: np203 stuck in 4X4

a tire iron seems a bit excessive just to get out of 4wd lol but if it works not much you can do

Re: np203 stuck in 4X4

it fit well and screwdrivers seemed small/weak
i'm thinkin it was more dirt and lack of lube in the "shifter linkage"
works a lot nicer then before
still gotta finish gettin the extra grease/oil/dirt mix off the caseing,under side too
