Auto gearbox problem
 

I have a 2014 isuzu dmax 2.5 i went out the other morning to find it wouldnt come out of park,
i noticed the dash wasn't registering it was even in park. Changed the TCM and and also the brake switch as i was told it was one of the two..
but still no luck the snap on dtc was saying it was a now a transmission range sensor but i dont want to keep throwing parts at it till it works.. has anyone had this any help would be great..
