NHTSA Complaint #10263972 — 1999 MITSUBISHI ECLIPSE SPYDER

TRANSMISSION STICKING BETWEEN 40-60 MILES PER HOUR AT 3000 RPMS AND HAS A PROBLEM SHIFTING DOWN CAUSING THE "SERVICE ENGINE SOON" LIGHT TO COME ON. THE PROBLEM HAPPENS ON THE SAME 2 ROADS IN THE SAME EXACT SPOT. I HAD THE PULSE GENERATORS IN THE TRANSMISSION REPLACED AND ONE WEEK LATER IT WAS DOING IT AGAIN. I AM TRYING TO DETERMINE IF IT IS AIR INTAKE RELATED SINCE IT HAPPENS ONLY AT THOSE 2 SPOTS ON THE ROAD. TRANSMISSION WAS DIAGNOSED OK (ON COMPUTER UNHOOKED TO THE ELECTRICAL COMPONENTS IN THE CAR) I AM TAKING IT BACK IN TODAY TO HAVE THE CODE READ AGAIN, HOWEVER IT RESETS ITSELF IF IT DOES NOT STICK FOR WHILE WHEN DRIVING. PROBLEM WAS INTERMITTENT STARTING AROUND AUGUST OF 2008 AND THE PROBLEM HAD BECOME MORE PERSISTENT UNTIL LAST WEEK 3/25/09 WHEN I HAD THE PULSE GENERATOR REPLACED. IT DID THE SAME THING 4/1/09 ONE WEEK LATER IN THE SAME 2 SPOTS ON THE ROAD. I THINK THE PROBLEM IS ELECTRICAL AND AIR TAKE RELATED BUT THE CODES GIVEN AT THE TIME IT IS DIAGNOSED IS NOT SPECIFIC ENOUGH. I WOULD LIKE TO SPEAK WITH A MITSUBISHI REP THAT CAN HELP DIAGNOSE THE ISSUE WITH OUT HAVING TO KEEP PAYING FOR IT SINCE I AM PRETTY SURE THAT THIS IS NOT A ONE TIME ISSUE. I WANT MY CAR FIXED BEFORE MORE DAMAGE IS DONE. *TR
