My Nissan Xterra 2001 model will not shift into higher gears after gears 1 & 2. This problem started after the high pressure tube connecting the gear system to the radiator got busted while I was driving on the high at a speed of about 100kph and I lost almost all the gear oil. I got the tube replaced and refilled the oil and then this problem started.

SOURCE: Lost door lock remote for 2001 Nissan Xterra.

You don't want to turn the security system completely off, besides there really is no need to. To arm and disarm the vehicle simply use the key in the drivers door. When you turn the key and lock the car the system will arm after about 30 seconds. When you come back to the car and unlock the car with the drivers door lock cylinder the system will unarm, just the same as if you were using the remote. If the system is unarmed and it still wont start you probably have a NATS issue with the key. This is different than simply disarming. You can't shut off or disarm the NATS system.

SOURCE: oil pressure needle at H

sounds like an oil pressure sening unit un plug it whilf its running and see if the gauge goes too zero,if not then the prob is the gauge, the sending unit is only about 15.00 at auto zone and easy too put in

SOURCE: Gear Shift gets stuck on Maxima 2001

The gear shift electrical relay or module inside it is not reading the signal to release. You need to have the electronic relay or module repaired or the gear shift assembly replaced.

i have the same problem 2005 xterra 4x2 giving pretty much all the code you posted but i did and tried everything possible to fix it myself with a little success but still ( Engine Light ) comes on with the last code P1757 front breake soleniod i did change the front passenger sensor but now the light came on again i believe the driver side need to replace as well ..... but weird the whining noise from the engine still there sound like i am going 120mph but actually im going 30mph only initiall problem was fixed by replacing the Transmission Oil 5 qrt S type from nissan dealer it did help for at least few months but then the problem came back... i also replace the Transmission Revolution speed sensor by doing that id just eliminate the code to pop up... i love my xterra but im getting really fraustrated everytime i see her in my garage colleccting dust not running.. dont want to spent a fortune rather thingking about trading it anyway like id said you might thingking replacing the Transmission oil that would maybe solve the issue.... GOOD LUCK....
