Transmission goes click ,click click right before shifting

700R4 goes click, click click when going very slow right before shifting. Click is in conjunction with jerk like timing is too fast but it is not the timing, loose U joints or slopy rear end. Definately coming form transmission. Also goes clunk when I shift into park. Seems to be getting worse.

First thing is check tv cable adjustment and fluid level. And do not keep driving it until you find issue

Checked both and they are fine. Been driving it with this click for a long time, albeit is is getting a little worse. Whole reason for the post is to give it more try at solving the problem before I just buy a new tranny.
