1995 Toyota Corolla Question: Is my ecu bad?

Sometimes when i'm driving either on the highway/city, my speedometer will start fluctuating and will hesitate to accelerate/jerk. It will snap out of it eventually and return to normal driving. The "O/D off" light will start flashing code 11. What do you think the problem is?
