Clunking on the downshift is common but usually can be easily remedied by runnning what we call a "quick learn" on the trans computer. It simply programs the computer to know how much volume of oil it takes to apply a certain clutch pack before the accumulater bottoms out. In this case it would be the underdrive clutch pack. The reason you don't feel it when in regular drive is because the u/d clutch is on in 1st thru 3rd and goes off in o/d...so when slowing down you feel the clunk when it makes a 4-3 downshift. Any loss of power to memory of the computer can cause this...blown fuse, dead battery, changing a battery.. ect. But, it can also happen if there is an internal pressure leak. I'd cerainly have a quick learn done first before any other action is taken, which any reputable transmission shop should do to begin with...hope that helped.

Wow! Didn't know the computer controlled the transmission that much. This is a recent purchase for me, having a 1987 Plymouth Voyager for many years now, and still going. So now I have the two mini-vans...
I do know that the battery had been removed, as shortly after I got it, I had to have the top strut housing reinforcing kits put in, and took it to someone that would not only glue and rivet it, but also weld it.
So the battery was off of it for a period of time.
And I did call a transmission shop and was told nothing about doing any 'quick learn' done through the computer system. Obviously I won't be going there!
I will for sure call around to other shops and question them about this, and when someone seems to know as much about this as you do, I will take it in and have this done.
I 'really' appreciate this information! I would have never imagined how much more complicated these newer vehicles can be, after driving my old 1987 all these years.
