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.
