2001 GC Hard downshift from OD
I have a 2001Grand Caravan EX 3.8l A604 trans and it shifts hard out of overdrive at about 25 mph. It started this after I changed the oil and filter in the transmission, before that it seemed fine. I seems weird because it is not consistent, sometimes it downshifts harder than others. I just bought the van and it has 116,000 miles on it. There also is trans fluid leaking from the solenoid valve bank cover. I put the Chevron ATF+4 in it and also tried some additive. Any ideas of what happened??[:@]

a leak at the solenoid pack from the front of the trans? I would replace the solenoid pack. Thats what controls a good bit of the shifting. Dodge does not recomend any additives in any of thier transmissions. (so i'm told). I would repair the solenoid pack and go from there.
there also may be a trip to the dealer in order for you, the reason for this is after you replace that its a good idea to do a quick learn on the trans. Its kinda of a calibration for the transmission control module to see where the clutches are

There is a flash update thru the dealer, and you maybe cover under the emission warranty? And replace the solenoid pack. You may need to drop the pan and ck the filter. sometimes if the o-ring as a cut it will suck air, causing a shifting problem. Use mopar atf+4 not chevron +4.
