car won't move when trans is in gear on 1992 Ford Taurus

My car won't move when I put the gear selector in any gear, reverse, drive, 2nd or low gear. I have 228K miles on the car but the trans was replaced at about 30K under warranty. I have changed the trans fluid on a regular basis. The rans did not give me any warning of going out like erratic shifting or hesitation. Here is the scenario, I changed the motor oil and filter, brought the car down, started and checked the oil level after I shut off the motor. After topping the oil, started the car, shifted into reverese, no go. I even shifted into drive, no go. Checked the trans fluid level, saw it was a little low but not enough to cause any harm, besides I just drove the car into the garage where I work!!! (One of the bennies our boss gave us) But I had to push the car out, couldn't leave it on the rack. Any help given would be greatly appreciated.

Sorry to see you didn't get an answer to your problem, we get a lot of questions and simply cannot answer them all. Did you need to have the transmission replaced again?
