Tried alt.autos.honda, no luck. Anyone have any ideas here?
Thanks
91 Accord 4 cyl AT, 200K
Cars runs great, looks pretty good, transmission slips in lower gears when
accelerating from stop or downshifting. It stays in the slipping mode but we
found that placing the shift lever in neutral, turning the key to the Off
position, restarting and shifting back to D allows the shift to occur.
Any thoughts appreciated.

====================

How many times have you done a drain-n-fill with Honda Z1 ATF?

I don't know the details of the Accord transmission but you might measure the
resistance of each of the control solenoids, especially if the problem is more
pronounced when the transmission is warm. I had a similar problem on my 1988
Prelude. It has two shift solenoids and two lock-up solenoids. Check your
service manual. You can probably open up a connector near the transmission or
at the control module to make the readings.

On my car 20 to 30 ohms is normal. I had some readings at 900 ohms! The
solenoids get hot and often won't release when the computer tells them to.
