please help.. trans problems

I have an automatic transmission and started my car this morning and first had trouble moving the car from park to drive, it wouldn't move. I restarted the car and it moved and the drive light on the dash started flashing. IT has trouble shifting. The drive light flashes and then when the car is in park the disangagement for moving the car from drive to reverse or 1 2 or 3 keeps clicking. Any ideas? If it is the trans should i get new or rebuilt? Any thoughts about level ten transmissions?

shoulda got a 5-speed... id say just convert the whole car to standard transmission

the codes say that its the solenoids but when i told the mechanic that i couldn't move the car from park to drive he thinks it is the automatic transmission computer. The car is working fine now so its probally intermident. I can pick one up on ebay like 30 bucks but i need to know where its located and how to do this. they want 200 -300 bucks to put in a computer!!!

thanks
