2006 dodge ram 2500, cummins , The problem is when I move the gear selector it highlights park and neutral when selector is moved but not reverse or any drives when running , but I noticed when key is in acc. position they all light up when placed in that gear . everything seems to be fine other than that . THANKS!!!!

 

So i assume it is driving in all gears ok? The gear shifter is electronic and located in the transmission itself
