My daughter's 93 Accord (160,000 mi) acted weird last Wednesday, we had it towed, and when I (finally) checked it today, the only thing I found was a bit too much transmission fluid. A few weeks ago, she said something was acting odd on her car. I went out to check under the hood and I saw that the transmission dipstick was out of its holder and resting an the crossmember and the opening for the dipstick. I was surprised that it hadn't dropped onto the road. Worried that dirt might have gotten in there, I drained the fluid and replaced it with more Honda auto trans fluid. Granted, I checked the fluid level when it was not all that warm and the car was on a slight angle (in the driveway). She had driven it steadily for a number of days, then she called this past Wednesday and said that it had barely gotten moving from a light and that the "D" indicator on the dash was blinking. I was out of state so I arranged for a tow truck to take it home so I could check it later. Today I drained the fluid and checked it ... looked great... put it back but checked it carefully on level surfaces to make sure it was not overfilled. I have left it low in the cross-hatched area when hot. It runs great. SO, any ideas what might have happened? Overfilled/foamed up? The old tow truck driver said "malfunctioning sensor", but I wouldn't know which one that could be. Could a "vent" be clogged, blowing out the dipstick a few weeks ago and causing it to malfunction this past week? The manual I have says something about a vent.. but where is it? My daughter doesn't want to drive the car - no faith in it now... (I had to replace the engine a few months ago after the camshaft snapped... the PO had not cared for the car well.) Before that new brakes, tires, window regulator, etc. Maybe I will just have to take it to CarMax and sell it. But with some door scratches I wonder whether I would get much for it! If it is something simple I would sure rather not just dump the car for wholesale. TIA.
