what gear box, there are 3 or4.
3/4/5speed and transfer case.?
what tranny what box.
does it make noise parked.?
or only moving>
stated all modes of travel , with and with out noise.
neutral is one.
does running free mean coasting.
on mine i have 5 forward gears, reverse,neutral 2wd./4H and 4L.
lots of modes.

there is no need to blead air from the gearbox or transfer, or diff's
first the transfer and gearbox are together but use their own oils and are changed seperatly
remove the drain plug to drain, refit then refill through the filler flug, the correct level is thesame as the filler so when starts draining from the filler hole its full. car needs to be level/flat ground when doing this.
if its auto there will be a tube for checking the level, at the back of the engine under the bonnet. auto trans oil does need the engine running to check for correct level.
remove drain plug with the engine off, refill approx same amount of oil in to the dipstick tube, then start the engine, select each gear for a couple of secconds then back to neutral, check level with engine still running. adjust level if needed.

N on the gearbox/transmission is Neutral for the transmission. Nuetral meaning that the power is not going anywhere so you are not going to move anywhere. The N next to the 2high, 4high, 4low is for the transfer case in nuetral. The transmission sends power through the transfer case and the transfer case sends the power to the rear wheels or front and rear wheels depending if it is in 2hi, 4hi or 4lo. The N setting for the transfer case is used when towing the vehicle with all wheels on the ground, like people do behind a big RV/motor home.

I assume it's a manual transmission.
If the car will not roll backward or forward in neutral (with or without the clutch engaged) the transmission is most likely locked in two gears at the same time.
This may happen if gear selectors are excessively worn. If you are able to examine the gear selection levers external to the gearbox, ensure they are in the 'neutral' (no gear selected) position when the gear lever is in Neutral. If not in correct position, you may be able to manually reset the levers to correct neutral position and thereby unlock the gearbox.
In any case, if it's happened once, it will happen again, so get the gearbox and gear selection mechanism checked for wear or breakage.

hi, this is a long shot so dont give me negative if no joy.
on the p38 they suffer from a bad electronic selector.
now, i do not have a clue what gear box or transfer you have.
any way if you look at your transfer, beside where the prop comes out, is ther like a window wiper motor with 6 wires.
if so they get stuck, rust or dirt etc.
have you checked your fuses, alos i would add. again not sure on your model.
in the fuse box there is a blank fuse, when inserted it shifts it to neutral.
the dealers wont tell you where it is.
have you put any fuses in etc, i did this 5 year ago, a p38 was jump started, leads wrong way.
i got a call as the aa did not want to help anymore. aa had a hand full of fuses out, i stuck in were contacts were. after new ecu had no drive.
you are sure its not a gearbox fault, get back to me if not sure, i can tell you how to test this.

use 15w-40 for the engine, ATF for the gearbox and 80w-90 for the diffs and transfer box. engine and gearbox have dipsticks for the levels, the diffs and transfer box have removable plugs for level checking, fill until the fluid comes out the level plug.
