AM A HONDA TECHDO U HAVE A WARRANTY WITH THE PEOPLE WHO REBUILT IT WELL ME PERSONALLY I NEVER REBUILD TRANSMISSIONS UNLESS IT MY OWN PERSONAL CAR OR ITS WARRANTY AT MY SHOP. I JUST SWAP THEM OUT BECAUSE YOU REPAIR THE GEARS AND THEN SOMETHING ELSE GOES OUT.REBUILT TRANS HAVE A BREAK IN PERIOD JUST LIKE A NEW CAR. YOU MUST DRIVE SLOW/ NORMAL FOR 1000 MILES WHEN ITS FIXED. UNTIL YOU START DRIVING LIKE A MAD MAN AGAIN BUT WHAT SOUNDS LIKE THE PROBLEM IS A STUCK SHIFT SOLENOID SAND A BAD TORQUE CONVERTER CLUTCH. I WOULD RECOMMEND DOING A TRANSMISSION DRAIN AND FILL (3 QUARTS) NOT A FLUSH. IF THIS DOESNT FIX THIS THEN YOU NEED A NEW TRANS.
