SEVERAL INCIDENTS OCCURRED WHERE WHEN DRIVING I WOULD BE IN DRIVE MODE, BUT WHILE ON THE FREEWAY GOING 60 MPH, OUT OF NO WHERE, MY TRANSMISSION WOULD SWITCH INTO LIMP MODE GOING 0 MPH OR 5-10 MPH. I WAS ALMOST HIT BY SEMI TRUCK. ANOTHER INCIDENT OCCURRED WHEN I WAS DRIVING, AND STOPPED BY THE RED LIGHT, SOON AS I PUT THE FOOT ON THE GAS, IT WENT ON LIMP MODE AGAIN AND MY CAR COMPLETELY STOPPED AT THE INTERSECTION DRIVING IN CITY, THE LIGHT TURNED RED, AND SOMEONE FROM THE INTERSECTING DIRECTION HAD TO SWERVE BEHIND MY CAR TO AVOID ME. THE SYMPTOMS SEEN WAS THE ALL THE GEARS "P, R, N, D" WOULD BE SELECTED, THE ANTI-ROLL OVER LIGHT, ENGINE LIGHT AND TRANSMISSION HEATING LIGHT WOULD BE ON. THE RPMS WOULD REV, BUT MOST OFTEN THE MPH STILL WOULD BE '0'. AT THE SHOP AFTER RUNNING DIAGNOSTICS, THEY FOUND OCCASIONS WHERE THEY FOUND "TCM LOST COMMUNICATION WITH COMPUTER" SEVERAL TIMES.
