My 2004 986 is showing the "Check Engine Light" and a rocking, rotating light runs back and forth between high and low gears dash display. This is an automatic transmission. An engine sensor read out says "Transmission shifter solenoid circuit malfunction". I cannot find anything on line about repairing this. Does anyone have a clue please?

The water pump went out and we replaced it and the thermostat. We are thinking possibly the water pump blew coolant into the shifting mechanism causing the solenoid issue.
