NHTSA Complaint #10993084 — 2014 HONDA ODYSSEY

TRANSMISSION BUCKING AT LOW SPEED AFTER DRIVING A WHILE. WHEN I DRIVE MY VAN OFF THE DRIVE WAY, EVERYTHING BEHAVES NORMALLY. THE ISSUE HAPPENS WHEN IT WAS DRIVEN FOR 30 MINUTES OR SO. AFTER ON THE FREEWAY FOR 30 MINUTES OR LONGER WHILE STOPPING AT THE OFF RAMP WAITING FOR THE GREEN LIGHT, THE VANS HAS PROBLEM TRYING TO SHIFT BETWEEN SPEED OF 20-40MPH. THE VANS BODY SHAKES VIOLENTLY AS IF IT WAS DRIVING ON A ROAD WITH MULTIPLE LOW SPEED BUMPS. THE TRANSMISSION HAS DIFFICULTY HUNTING FOR THE CORRECT GEAR. I CAN SEE THE RPM MOVING UP AND DOWN CRAZILY AS IF IT ENGAGES A LOWER GEAR AND IMMEDIATELY DECIDES TO SWITCH TO HIGHER GEAR MULTIPLE TIMES. THE PROBLEM IS MOST PROMINENT WHEN THE VEHICLE IS AT COMPLETE STOPS AND TRYING TO SPEED UP ON THE INCLINE STREET. WHEN IT IS ON HIGH SPEED, SUCH AS 50 MPH AND ABOVE, IT DRIVES SMOOTHLY. I THINK THE VEHICLE IS TRYING TO COMPENSATE BETWEEN BEST GEAR RATIO AND BEST FUEL ECONOMY GEAR AT THE GIVEN SPEED. A THE SPEED WHERE CONSTANT SPEED IS NOT ACHIEVED SUCH AS HILL CLIMBING OR ACCELERATING FROM STOP AT THE OFF RAMP TRAFFIC LIGHT, THE COMPUTER CONFUSED.
