I saw in one of your posts that the trans fluid level could be a quart to a quart and a half low. Did you top off the fluid level?
Any Mopar trans I've ever had that was a quart low functioned poorly after the trans warmed up.

The 1st step in troubleshooting an auto trans was to be sure the fluid level was correct, not low, and not over full. With the fluid warm, vehicle on a level surface, trans in neutral (newer stuff is in park, but park doesn't work on the old transmissions), the fluid level should be at the full mark. If it isn't add, if its more the the distance between the "add and the full" above the full line, drain some out.

Until the fluid level is correct, almost every test will give incorrect info..
