I need HELP! I have an 2003 4.7 automatic with an PCM and TCM, I parked the truck and and week later I noticed that the shift indicator light is not working and when I put the truack in Drive the engine revs more than it moves, if I put the trans in 1 it will take off......and it will down shift manually however the OD button does not work and there is no indication on the gauge cluster and when downshifting manually there is no OD. I have already replaced the PCM and the TCM........Can someone shed some light? Thanks in advance
