At this point there are a few possibilities as to what the problem may be... I replaced my off color VSS a few years ago because of crankiness....
what tell the pcm its in what gear then i just doesnt know off hand
maybe the Neutral safety switch

So, the pot hole... could that have cracked the tranny or put a hole in it?
Adding fluid, and it works fine....... I say you might have a leak.... keep the level good on the tranny, and start it, and look for any kind of leaks.....
Could be the high pressure line from the tranny to the radiator/cooler thats leaking.....

The PCM at the right speeds will command the tranny solenoids in a manner that will start the car off in first gear, I think its actually solenoids A and B off(not sure)... But there is a switch for 2nd,3rd and 4th gears inside the transmission so that the PCM will know the tranny is in the proper gear... and without the 3rd or 4th gear switch, chances are that the tranny will shift, but there will be no TCC apply and the SES light will most likely illuminate...
