MANY TIMES, MY CAR DOES NOT DOWN SHIFT AFTER BEING IN A PASSING GEAR AND THEN LETTING OFF THE GAS. IT STAYS AT 5,000 RPM FOR A FEW SECONDS. JULY, 2018, MY CAR WAS STOPPED AS I WAS WAITING TO MAKE A LEFT TURN. AS I PRESSED ON THE GAS TO TURN LEFT, MY CAR SLIPPED INTO NEUTRAL. BECAUSE MY BRAKE LIGHTS WEREN'T ON, MY CAR WAS HIT FROM BEHIND BY AN APPROACHING CAR. SEPTEMBER 3, 2018 MY CAR WAS STOPPED, I PUT IT INTO REVERSE TO BACK INTO A PARKING SPOT. WHEN I PRESSED THE ACCELERATOR THE CAR SHIMMIED AND MOVED FORWARD INSTEAD OF REVERSE.
