I don't recall much of the information you're looking for being in the manual(s). Also, I believe all the things you're considering adjusting are either double-nutted or have safety wire so I'm doubting something has come loose (and mis-adjusted itself). Basically, I think an adjustment would be covering up an issue.
In almost every RTV I've seen that has encountered a similar issue, it's worked out to be that the tranny fluid and filters need replaced. If the flow isn't good, you'll encounter the conditions you mentioned. Have you been doing the incremental fluid/filter changes and using the SUDT fluid?
