I have recently noticed the "D" light on my shift indicator of my 2004 Honda CR-V EX flash when I put the car in "P" or "R." Actually, I can also see the "D" pulsing when I am driving, so I know that it is flashing then, as well. This problem started about four months ago and does not occur that often - perhaps once every week, or two. While experimenting with this, I put the car in "2" while stopped with the engine running. On this occasion, I could not get the car out of "2" and turned the car off to see whether that made a difference. I could not start the car, since the shift lever was stuck in "2." With my mechanic on the phone, I searched for an override switch but could find none. About 15 minutes later, I was able to move the shifter to "P" and could restart the car.
I should point out that I have experienced no problems driving the car. It seems to shift normally and smoothly. However, the flashing "D" together with the car being stuck in "2" has me worried that I may be seeing a problem. My mechanic says that he cannot use his computer to tell the error that is being reported unless the "D" is flashing at the time. But the flashing "D" is unpredictable and always seems to happen when I am not convenient to his shop or it is after hours.
My mechanic doesn't work on transmissions and suggested I go to the Honda dealer to check it out or to AAMCO and have the transmission oil flushed. The car has about 120k on it and, though I regularly maintain it, I do not know the last time that the transmission oil was changed.
If I go to the dealer, I know that I'll be charged about $100 to hook the car to the computer and I still may not know any result. And, to be quite honest, I have little confidence in the trustworthiness of my dealer's service department, based on past experience. If I have the transmission flushed, I'll probably end up spending $150, or so, and may still have the problem.
I've researched the problem and seen that this could be caused by a faulty switch, old transmission oil or a cooked transmission. I would think that, if the problem is the latter, I'd be experiencing more symptoms.
At any rate, I'd like to submit the question as to how best to proceed to see if I can get some helpful advice.
Thanks in advance,
