I have a 2000 jaguar s-type 3.0 with 79,900 miles and I recently encountered the gearbox fault light coming on, when I plugged in the code reader it said solenoid c and d faulted. The check engine light has come on as well but it shows no other codes thrown. It shifts fine and only has a slight lack in power from 1st to 2nd gear upon acceleration but still beats most cars off the line at the light. Not sure what I should do to get rid of the lights on the dash, any suggestions?
