2003 TOYOTA 4 RUNNER Power Trainautomatic Transmission Problems

WHEN COMING TO A STOP AND/OR ACCELERATING FROM A STOP THE CAR WILL JERK FORWARD WITH A THUD. SOMETIMES TWO OR THREE THUDS ARE FELT AND HEARD. THE DEALER WITNESSED THIS PROBLEM AND OURISMAN TOYOTA IN CHANTILLY, VA REPLACED THE TRANSMISSION AT 14,500 MILES. THE PROBLEM SEEMED TO GO AWAY FOR A WHILE. I RETURNED TO THE SAME DEALER WITH THE SAME COMPLAINT AT 32,000 MILES AND THEY REPLACED THE DRIVE SHAFT. I RETURNED AGAIN ON 11/30/04 AND THE SERVICE MANAGER WITNESSED THE SAME PROBLEM WITHIN 200 FEET OF DRIVING. THE SERVICE MANAGER INDICATED HE BELIEVES THIS IS NORMAL (EVEN THOUGH THIS WAS NOT A PROBLEM TILL ABOUT 12,000 MILES). HE IS GOING TO DISCUSS THIS WITH THE TOYOTA REP WHO IS IN TOWN THIS WEEK.*AK I

THIS CONDITION COULD BE RELATED TO ITEM 2. THIS CONDITION STARTED LAST WINTER AND IS GETTING WORSE.) AFTER BEING AT A STOP AND RELEASING THE BRAKES, I GET A HARD SHAKE/THUD FROM THE DRIVELINE/BRAKES. THIS OCCURS IN 90% OF STOPS/STARTS. (E.G., IF IT WAS NORMAL, IT WOULD DO IT ALL THE TIME TO SOME DEGREE.) THERE IS NO METAL ON METAL NOISE, JUST THE SHAKE/THUD LIKE THE BRAKES ARE RELEASING TOO HARD OR THE DRIVELINE HAS TOO MUCH LASH IN IT. (CONDITION IS WORSE IF YOU COME TO A HARD STOP, BEFORE STARTING AGAIN.) 2) SOMETIMES (ABOUT 20% OF THE TIME) AFTER COMING TO A COMPLETE STOP AT A STOP SIGN OR RED LIGHT, THE TRANSMISSION GOES INTO FIRST GEAR HARD AND/OR THE CONVERTER/TORSEN DIFFERENTIAL IS UNLOCKING/LOCKING INCORRECTLY. IT WILL ACTUALLY ROCK THE VEHICLE FORWARD. SOMETIMES IT GIVES THE SAME SENSATION AS IN ITEM 3. (ACTUALLY, ON A FEW OCCASIONS...

GATED SHIFTER, ON 2003 TOYOTA 4 RUNNER, ALLOWS YOU TO SHIFT THE VEHICLE PAST NEUTRAL (INTO REVERSE OR EVEN PARK) WHILE DRIVING, WITH OUT DEPRESSING THE BRAKE PEDAL. IF YOU PUSH STRAIGHT UP ON THE SHIFTER IT LOCKS IT OUT (AGAINST THE STAGGERED PLASTIC OF THE GATED SHIFTER). BUT IF YOU ACCIDENTALLY HIT THE SHIFTER ON AN ANGLE, IT CAN SLIDE PAST NEUTRAL AND INTO REVERSE OR EVEN PARK!*AK

MY WIFE WAS DRIVING HER 2003 TOYOTA 4RUNNER LIMITED,V8 WHEN THE TRANSMISSION POPPED OUT OF GEAR.SHE HAD IT IN 4D GEAR FOR NORMAL DRIVING.SHE PULLED OVER AND PUT IT IN 4D GEAR AGAIN AND IT POPPED OUT A SECOND TIME.THE CHECK ENGINE LIGHT ALSO APPEARED. SHE PULLED OVER AGAIN AND TURNED OFF THE AIR CONDITIONER AND SHE PROCEEDED TO DRIVE TO HER DESTINATION WITHOUT THE GEAR POPPING OUT.SHE CALLED OUR SON TO PICK UP THE CAR TO TAKE IT TO THE DEALER FOR SERVICE.THEY FOUND NOTHING WRONG WITH THE VEHICLE. THEY SAID IT HAD TO HAPPEN WHILE THEY WERE TESTING THE CAR TO FIX THE PROBLEM BUT THEY COULDN'T REPEAT THE SAME THING THAT HAPPENED WHEN MY WIFE WAS DRIVING IT. THIS SITUATION COULD BE POTENTIALLY DANGEROUS.WHERE DO WE GO FROM HERE,WHO DO WE CONTACT? MY WIFE'S WORK NUMBER IS 412-875-1481
