2007 TOYOTA FJ CRUISER Engine And Engine Coolingengine Problems

THIS IS A TOYOTA ECM COMPUTER ELECTRICAL MALFUNCTION. I WAS WAITING IN MY 2007 TOYOTA FJ CRUISER AT A TRAFFIC STOP FOR THE LIGHT TO CHANGE FROM RED TO GREEN. AT THIS TIME, I FELT A HARD "BUMP" AS IF ANOTHER CAR HAD REAR-ENDED MY FJ. THERE WAS THIS REAL HARD "THUMP." THE FJ HAD SHIFTED GEARS ON ITS OWN WHILE AT A COMPLETE STOP. EITHER THE TRANSFER CASE DIFFERENTIAL AND/OR THE ELECTRICAL REAR DIFFERENTIAL LOCKED UP. BOTH MY HANDS WERE ON THE STEERING WHEEL AND MY RIGHT FOOT WAS ON THE BRAKE AT THE TIME.

THIS CAUSES THE VEHICLE (MANUAL TRANSMISSION) TO SPEED UP INSTEAD OF SLOWING DOWN, EXACTLY THE OPPOSITE OF THE "ENGINE BRAKING" THAT ONE WOULD EXPECT. I FEEL THIS PRESENTS A MAJOR SAFETY HAZARD WHEN DRIVING IN TRAFFIC AND / OR ICY ROAD CONDITIONS. *JB
