'Trans ecu defective'

05 S500 .. code showing for defective trans ecu. Trans shifts v smooth up through 7 gears. On way down, depending on speed, there is a jerk at low speed due to skipping of a gear going down inherent to the 7 speed. So .. do I attack the ecu code .. or leave it alone for now??
