I JUST GOT THIS 2006 CHRYSLER PACIFIC FROM A POLICE INMPOUND AUCTION. EVERYTHING TURNS OUT TO BE RUNNING GOOD ON THE TRUCK. I FLUSH THE ENGINE OIL AND TRANSMISSION FUILDS AT A SHOP AND THEN DROVE IT FROM NEW YORK CITY TO ATLANTA GEORGIA. THE CHECK ENGINE LIGHT COMES ON AND READ PO700 AND PO740. I DONT HAVE NO TRANSMISSION PROBLEMS AT ALL. IT SHIFT FINE WITH NO ISSUES AND HAS NO DELAY. I BEEN READING ON THIS FORM FOR ABOUT TWO WEEKS NOW. I TEST THE ALTERNATOR AT AUTOZONE AND THEY SAY IT READ 14.4V. NOW I REPLACE THE TRANSMISSION solenoid pack $ 161.34 FROM THE DEALER AND THINK IT SOLVE THE ISSUES. THE LIGHT CAME BACK ON AFTER 12.7 MILES DRIVEING. HMM MY HEAD IS HURTING. PEOPLE SAY A BAD DIODE CAN cause all kinds of bizarre secondary problems. I LOOK AT THIS VIDEO ON YOUTUBE ABOUT A GUY TESTING >> . CAN SOMEING HELP ME WITH THIS ISSUES
