ENGINE AND ENGINE COOLING
FOUND THE EXHAUST MANIFOLD BOLTS ON BOTH SIDES OF THE ENGINE SNAPPING OFF FOR NO REASON AT ABOUT 65K MILES. WHEN I ASKED THE LOCAL DEALER ABOUT THIS THEY STATED THEY WOULD NEED TO REMOVE AND RESET THE ENGINE HEADS IN ORDER TO REMOVE THE BROKEN BOLTS. I DID NOT HAVE THEM REPAIR THE PROBLEM DUE TO THE COST THEY QUOTED. I NOW HAVE THREE BOLTS ON EACH SIDE WHICH HOLD THE MANIFOLDS IN PLACE. THE PROBLEM SEAM TO HAPPEN AT THE CHANGE OF THE SEASON FROM FALL TO WINTER. IN THE EXTREME COLD WEATHER, ON A COLD START UP, THERE IS AN OBVIOUS EXHAUST LEAK. AS THE ENGINE HEATS UP THE LEAK DOES DISAPPEAR. THIS IS A SAFETY HAZARD DUE TO THE FACT IF THE ENGINE EXHAUST BLOW BY IS TRANSFERRED INTO THE CAB THE DRIVER COULD BECOME UNCONSCIOUS AND DEATH COULD OCCUR. *TR

POWER TRAIN
TRANSMISSION DELAY FROM PARK TO DRIVE. AS TRANSMISSION MOVES INTO DRIVE THE TRUCK JERKS FORWARD VIOLENTLY. PARK TO REVERSE DID NOT SEEM TO BE A PROBLEM. DEALER WORKED ON THE TRUCK FOR APPROXIMATELY 8 HOURS, FLUSHED TRANSMISSION, AND PERFORMED OIL CHANGE, DID NOT NOTICE ANY METAL IN THE TRANSMISSION FLUID AND SOUGHT AN UPDATE FOR THE TCM (WAS UP-TO-DATE); HOWEVER, A SMALL AMOUNT OF WATER WAS SEEN IN THE OIL PAN. DEALER PERFORMED A TEST DRIVE AND THE TRUCK APPEARED TO BE BACK IN WORKING CONDITION. OWNER ATTEMPTED TO DRIVE THE TRUCK OUT OF THE DEALER LOT BUT THE TRANSMISSION WOULD NOT ENGAGE. OWNER ATTEMPTED TO PUT THE TRUCK IN REVERSE, THE TRANSMISSION WOULD NOT ENGAGE. TRUCK WAS LEFT AT THE DEALER FOR FURTHER EVALUATION. NO ADDITIONAL INFORMATION AT THIS TIME. TRANSMISSION STILL UNDER WARRANTY. *TR
