Hopefully everything is good after replacing the sensor. I would check your transmission fluid and even if it's red, I would replace it anyways just to be on the safe side. Honda has released a new fluid called DW-1 and it's a full synthetic. It seems to have helped the transmissions as it has a higher heat tolerance which is what causes our transmission to fail. I put some in my car and it shifts much faster than before and it's smoother as well.
