I have a 2003 nissan exterra, and the same thing as this guy

Customer Question

Hi, I have a 2003 nissan exterra, and the same thing as this guy happened to me, AND I jumpered the 3 and 5 and it started. Except it only drives in 2nd gear. We bought a new neutral switch as autozone and I installed it and it would not start. I called nissan and he said to loosen the switch and range it back and forth while someone keys the ignition and nothing happened. He said it could be a fault in the harness some where or the security system. Well I think it has a factory security system. I checked everywhere and the wiring under the dash looks factory and nothing under the seats. I have no idea if autozone gave us the wrong switch, everything including the wiring looks the same. I have no way of knowing where to start to find a fault in the harness or security system. i will gladly pay you if you can help me get through this before my wife takes it to nissan on monday. I put everything back together, lined up the switch and we are driving in second gear. Please help. Thanks.

Hello and welcome to JustAnswer!

The problem could be with the range sensor's wiring but it isn't that likely if there are no visible wiring or connection issues. I question whether the transmission control module is awake, it may be down due to an internal failure or a loss of power or ground.

Do you have a scan tool or code reader to check for communication with the TCM?
