The codes will not remain from the old trans, and they should be identical if they are from the same VIN. The connector should also be the same, it is a 20 pin connector, with 14 wires, and they should be wired the same. You said you checked the solenoids, how was that accomplished? A few things need to be considered in doing this, one is that the solenoids mechanically function, it needs to be verified that they can be turned on and off(i.E. Are getting signal from PCM). The solenoids are the same, so one could be switched with the other to see if the code/symptom changes. The lower valve body has to be removed to change them. Look closely at the little black square between the solenoids. Early design had no means of retaining that filter, and eventually it could push out and break the solenoid. A new solenoid kit would include a bracket and longer bolt to upgrade and prevent that from reoccurring. It could be that the base of the solenoid is cracked, and it is not able to perform it's hydraulic function correctly.
