Try disconnecting the battery for 5 to8 minutes. That will usually rest the ECU. If it persists, I would think you might have the wrong size reservoir or just by coincidence you may have broken a wire or the sensor failed.
As far as the transmission goes, when there is no dip stick it is called a, "sealed transmission". Not a lot of manufacturers use it. The only one I have seen is BMW. You might find a fill plug or have a dealer check it but I am not sure. If it is the same car get back to me and I will see what I can find out. However if it is sealed I won't get any more information than that or the fluid capacity.
Let me know if this helps.
