Well, when the problem happened it was pretty hot. Since then I tried to
limit my driving during the cooler parts of the day and for short
distances, just in case it was heat related.

Only the solenoid will be replaced.

I agree but I am willing to risk the couple hundred dollars for the
solenoid that will probably give me a good case to have the problem
fixed for free if it turns out that not the solenoid was the culprit. I
will also make sure to get the old solenoid from them.

You are obviously handier with these thing than I am.
By the way, I wonder if there ever was a Honda service bulletin issued
on this subject. Is there any place on the Net where one can find all
Honda SBs?

Thanks, I did just that and found a lot of interesting stuff there but
nothing directly relating to my specific issue.

Oops. I was thinking solenoids and wrote computer module.
The damage to your wallet from a new solenoid assembly should be less than
$200 plus labor.

There's a good TSB about the solenoids in the CLUTCH / TRANSMISSION
section he

Actually $247.

Not applicable for my case though.

Well, at last my Honda dealer got the shift control solenoid and
installed it. That gives me now some peace of mind. However, I still
wonder if the short drive (about 3 miles) that took me to get the
crippled car home caused any other damage in the A/T. Since the lower
gears did not engage, there must have been excessive wear on the clutch
pads inside, just as if you try to start a M/T car in 3rd or 4th gear.
When I got home I could even smell a slight burn odor which I figured
must have been caused by the friction from the clutch pads. If my guess
is right, the ATF then must have absorbed a bunch of burned particles
from that pads and maybe at a minimum the A/T should be flushed. I was
kinda' surprised that the Honda service techies did not call my
attention to this. Am I perhaps too concerned here?

The usual default gears when the transmission computer goes into impaired
operation mode are second and fourth. You start out in second and, skipping
third, go to fourth.

It's unlikely that you smelled something from the transmission. The
transmission is sealed. The only possible opening is the dipstick tube.

Pull out the transmission dipstick. The fluid should be pink and not smell
burnt.

Yes.

I wish I had known that. My usual habit is to set the gear into 3rd when
I am in the city with max. 35 MPH speed limit. I think that's what I was
doing then. Thanks for this info anyway. It might come handy one day.

I checked and it still looks pink w/o any burnt smell.

Good! :-)

the clutch packs only slip during the actual shift. after that, any
differential is taken up by the torque converter.
