NHTSA Complaint #10427130 — 2003 TOYOTA 4RUNNER

VEHICLE HAS A LOW GEAR SOUND WHICH BEGAN WHEN VEHICLE WAS RELATIVELY NEW AS I TRAVELLED DOWN SLIGHT GRADES. I NEVER COMPLAINED BECAUSE THAT WAS THE ONLY TIME IT SEEMED ABNORMAL AND THERE ARE ONLY A VERY PLACES IN MY TOWN WHERE THE HILL WAS STEEP ENOUGH TO CAUSE IT. PLUS I ASSUMED IT WAS RELATED TO THE TRAC BRAKING SYSTEM AND MIGHT BE NORMAL. LAST WEEKEND ON A 5 HOUR TRIP EACH WAY THE PROBLEM BEGAN TO MANIFEST ITSELF AS I ACCELLERATED ON FLAT GROUND. THE TACHOMETER SHOWED LOW RPMS (UNDER 2000) UNTIL 50-60 MPH. HOWEVER THE SOUND WAS MUCH MORE NOTICIBLE WITH SOME ADDITIONAL VIBRATION. THE VIBRATION IS NOW WORSE, COULD IT BE A SPEED SENSOR PROBLEM?
