What happens is the wires break at pivot of base of shifter, if you remove column covers you will see broken wires at base where shifter manual wires flex when shifting lever, you can try and repair wires or replace the shift arm to fix this problem. Thank you, XXXXX XXXXX know if you have any more questions, ROY!
let me know if you need any more help ,Thank you ROY!
Your covers are the plastic covers that go around behind the steering wheel to get to the shifter lever . if transmission is getting hot and grinding I would start with a transmission service and also make sure your fan motor is working at front of truck when hot . if binding in 4WD you will need to get the actuator inspected on side of transfer case for problems sticking in gear , these can also fail This could still be covered under your Nissan warranty . Thank you ROY!
