02 Grand Caravan will not Move fwd or rev

To set the stage, I had the TCM replaced about 5 years ago by a shop after it went into limp mode.I changed the trans filter at about 100,000 miles. Ive had no problems before or since with the engine or transmission until now. Yesterday my wife was driving to town and she said it felt and sounded like a rough down shift and then the van just coasted to a stop and she shut it off ( NOT going into Limp mode). When I got there the van would start fine and the park pawl seemd to be engaged ( would not roll). When I shifted from park to rev, the shift change sounded and felt normal (slight rpm change) but no movement, just coast. Rev to Neu sound and felt normal. Neu to Drive also sound and felt normal but still no movement just coast, still no limp mode. By coast I mean it can be in R or D and I can push the van like it was in Neutral.
I got the van home and started my checks, trans fluid full at warm idle, no leaks, shift linkage in tact and working properly also is not loose. Pulled on wiring harnesses and do not see any wiring cut or worn. I checked codes to find P07000 ( trans control system), P0720( output shaft sensor) P0715( Input speed sensor). I cleared the codes and after some research I have replaced both of these sensors, input and output speed sensors. Also I have replaced the Transmission Solenoid Pack after removing the plug with the 8mm bolt and finding fluid leaking through the electrical connector. I found the TSP leakage problem while researching and figured it would be good to change preventativly even though it wasn't leaking too bad.
I replaced the Transmission filter and gasket and filled with fresh +4 atf fluid. The magnet in the pan had very fine shavings on it about a 1/16 thick.
After each part I replaced I would start the van and shift through the gears hoping to find the fix, but the symptoms are still the same, no fwd or rev movement just coasting.
Since clearing the codes I have rechecked for codes several times but none are coming back. I have also diconnected the battery for 5 min and turned the ignition key to try and reset the control modules.
