Saturn Repair: Saturn Transmission, saturn transmission, saturn sl1

Question
I have a 1993 Saturn SL1 that is having transmission problems. I fist replaced the transmission, I continued to have similar problems with the trans. I was told it was the Trans Control Module or Computer, which I resently replaced. I am still having the same problems with the trans not staying in gear or not shifting out of 1st gear.
What else can it be?

Answer
I don't know much about this particular problem BUT, from past experience with other models, the trans has solenoids that operate to tell it to switch at particular speeds, based on sensors that tell it info.  There is info from a speed sensor, a Temporature sensor, and it also gathers info from the cars main engine control module (computer) and compares it to the Trans control module.  I would bet it is merely one of the sensors that is reporting bad info to the trans control unit.  Sorry I cant offer more info.
