I HAVE A PROBLEM WITH MY SPEEDOMETER. EVERY DAY AFTER DRIVING IT FOR 30 +/- MILES THE SPEEDOMETER STOPS. SOMETIMES AT 50 SOMETIMES AT 0 MPH. ONCE I BEGIN TO DRIVE IT WILL SOMETIMES GO FROM 50 TO 100 OR IT WILL STAY WHERE IT STOPPED. THIS STARTED ABOUT 18 MONTHS AGO BUT IT ONLY HAPPENED ONCE EVERY COUPLE MONTHS. NOW IT HAPPENS DAILY. I HAVE LEARNED THAT AFTER LEAVING IT SET FOR A FEW HOURS I START IT UP, PUT IT INTO DRIVE AND TURN IT OFF. WITH THE GEARSHIFT IN DRIVE I TRY STARTING IT AND EACH TIME I TURN THE KEY THE SPEEDOMETER GOES FROM 50 TO 40 TO 30 AND THEN BACK TO 0. ONCE AT ZERO I START THE TRUCK AND THE SPEEDOMETER WILL BE ACCURATE FOR AT LEAST 30+/- MILES. *TR
