I'm out of ideas of what the problem is with the truck. When you go from park into reverse it slams into gear, when you go into drive it pulls/lurches foward with moderate pressure on the brake, when its in neutral it says its in 3rd gear and none of the other gears on the PRNDL light up when in gear. It drives down the road just fine when I get it in gear but it does not want to change gears. I've already replaced the neutral safety switch and it went away for a few weeks, then this morning it came back. I took off the transmision end of the shift cable and messed with it a bit kinda testing it and put it back, that stopped the slamming and right now works a bit better but it still doesnt show display on the PRNDL. Anyone have any ideas of what I could do to fix my problem?
