Some mornings when there is a chill in the air, my shifter lights that correspond with the lever for "D" wont work. if I put the car in 4th and run till it gets warm it will then light up when I put it in "D". Without the light being on the car won't go into high gear when driving. Can the unit in the shifter that runs the lights be replaced or adjusted? I would like to hear some feedback on this ....Thanks
