My '02 Caravan with 4-speed automatic has begun to exhibit a problem
that was dealt with, once, about 20,000 miles ago. I'd like to hear
about anyone else's experience with this:
1. Sometimes, while trying to get under way at the first startup of
the day, I experience a "no drive" condition. Placing the gear
selector in forward or reverse has the same effect as leaving the
selector in neutral. No torque is transmitted. Placing the selector
back in park and waiting briefly before trying again usually results
in the trans going into gear and operating as expected on the next
2. Decelerating from ~40 MPH or so, service brake applied, the
downshift from fourth to third at about 30 MPH is very harsh. Only
this one downshift is unusual. All other shifts, up or down, are
The fluid is clean, and the level is correct (checked at operating
temperature). Fluid and filter were changed once at about 20,000 miles
(BEFORE this same problem developed the first time). The car has now
done about 45,000 miles.
The remedy when this happened before, was for the dealer to re-program
the transmission control module. I have an appointment for them to
diagnose and correct the problem in a few days. Is this a recurring
thing for anyone else? Is there a known problem with the transmission
or the control module?
I'd appreciate hearing from anyone who can shed light on this.
