Summary
"ISSUE: A SMALL NUMBER OF CUSTOMERS MAY EXPERIENCE THE FOLLOWING PROBLEM, AFTER ATTEMPTING TO SHIFT INTO REVERSE GEAR: TRANSMISSION DOES NOT SHIFT INTO REVERSE. THE CUSTOMER MAY ALSO NOTICE A FLASHING 'R' ON THE TRANSMISSION SELECTOR AND INSTRUMENT CLUSTER. 'TRANSMISSION FAULT' MESSAGE IS DISPLAYED IN THE MESSAGE CENTRE. REVERSE GEAR CANNOT BE SELECTED, THOUGH THE FAULT MAY CLEAR IF IGNITION IS SWITCHED OFF FOR AT LEAST 30 SECONDS. VEHICLE WILL OPERATE AS NORMAL IN ALL FORWARD GEARS. UPON INSPECTION, THE VEHICLE EXHIBITS NO RELEVANT DIAGNOSTIC TROUBLE CODES (DTCS). CAUSE: THIS PROBLEM IS CAUSED BY A SOFTWARE ERROR WITHIN THE TRANSMISSION CONTROL MODULE (TCM), AND JLR ENGINEERS ARE URGENTLY SEEKING RESOLUTION."
