Hello I manage a retirement apartment building. And help many older people with things like this with spare time. This is what one says:

I am getting a down shift clunk around 25 mph when i am stopping. If shifted into neutral during braking it does not do it. I am planning on replacing the transmission filter, do I need to replace the fluid with Dex 4, or synthetic?? Would this also explain the fact that when I start cold and go from reverse to drive (or visa versa) that I have no transmission engagement right away. Also when I stop the engine has to get to 2000 rpm to engage the transmission again? After it warms up it engages better?
Also when i do these repairs or advise. Were can i get pictures and instructions online for free?...some of these people have money but all are very tight with it lol

To me it sounds like you are correct that I would start with a transmission service with a new filter, also I have seen the input shaft sensor cause this issue as well so if the service does not help I would swap the sensor out, it can be off enough to cause the problem but not enough to trigger a trouble code FYI. Here is a guide to help you and I have included how to do the job and the sensor location in the images below.

Pour four quarts of Mopar ATF+4 (Automatic Transmission Fluid) Type 9602 through the dipstick opening.


Check out the images (below). Please let us know what happens.
