NHTSA Complaint #11208299 — 2008 FORD EDGE

TRANSMISSION SLIPPING AND DOWNSHIFTING HARD - AROUND 80,000K I STARTED TO NOTICE THAT THE TRANSMISSION WOULD BANG WHEN I PUT IT IN REVERSE. AFTER THAT, OTHER ISSUES STARTED HAPPENING - WHILE PRESSING THE GAS PEDAL, VEHICLE WOULD NOT SWITCH TO A HIGHER GEAR. I'D HAVE TO COME TO A COMPLETE STOP (IN TRAFFIC!), PUT IT IN PARK, THEN TRY TO DRIVE AGAIN. PERIODS WHEN THE VEHICLE WOULD GET TO SPEED THEN SLIP. TRANSMISSION WOULD BANG LIKE I WAS BEING REAR-ENDED. CHANGED THE VALVE BODY, TSS, AND OSS SENSORS. THAT WORKED FOR A WHILE BUT NOW IT'S ACTING UP AGAIN. DOWNSHIFTS SO HARD AND BANGS WHILE I'M DRIVING AT VARIOUS SPEEDS. I'M AFRAID IT'S GOING TO GO COMPLETELY WHILE I'M DRIVING. THERE WAS NO PRIOR DAMAGE TO VEHICLE TO CAUSE THIS MALFUNCTION.
