A131L transmission not engaging in any gear

I hope someone can help. I have recently replaced my 4afe motor with a salvaged one. My a131l transmission was in good shape when the old motor went out and the mating of the new motor to transmission went pretty smooth. I never took the torque converter out and did not unplug any of the wiring harness from the transmission. When the new motor fired up I took it for a test drive and everything worked great so I parked it in my driveway for about three hours then went to take it out and there is absolutely no response in any gear, the car dose not even try to move. I checked the oil and it was unusually high so I thought the torque converter may have drained into the pan somehow. I have now pulled the pan to check the oil pickup and filter and everything looks fine besides a very small amount of metallic particles. (Nothing worse than I have seen in working transmissions) I have checked all my fuses, tv cable, shift linkage and do not know what else to look for. The only thing I can think is something I did during the mating process. Please help! Anything is appreciated.
