Some background:
Your car may still have ATF+3 in it unless it's been changed. You
should have been changing the fluid periodically. To get a more
complete changeout to ATF+4, you will need more than just a simple pan
drop (system holds 10 qts. - pan drop only replaces 4 to 5 qts.). ATF+4
is superior to ATF+3.
Also, Chrysler went thru a few revisions of the firmware to tweak that
kind of problem out of the 42LE. There was one update that my Concorde
needed for the exact same problem, and it fixed it for good - and mine's
a '99.
Try the following in the order given (checking to see if problem
resolved after each step - stop when problem resolved):
(1) Reset TCM (by pulling its fuse for 5 minutes)
(2) Fluid filter change
(3) Reset TCM
(4) Update TCM firmware to latest revision (pay dealer to do this -
anywhere from $60 to $140 depending on dealer).
