Needing someone to help with w124 transmission vac/other issues in ohio

[1977busman]

Ok ive gotten to the point that my time is worth more than my money, and I am looking for someone preferably within 1-2 hours of central ohio that would be willing to work on my 300d's transmission.
Here is some back ground:
-very slight flare when I got bought it 6500miles ago
-Decided to replace vaccum lines and connectors to help flare
-Flare got much worse after step above^^
-Now flares 150-300rpm on some shifts and others it clunks in the rear or shifts very hard.
-Somedays are MUCH worse than others for no apparant reason.
-Adjusted the modulator on tranny some, but without much effect.
-I have the opportunity to buy a 150k-ish miles tranny off ashedd if all else fails, but I want to make sure that its not just an adjustment, that could fix the issue without a tranny replacement.

The only part that confuses me is that some of the shifts flare alot, and others clunk/shift hard. In my past experience I have had either all hard shifts or all flaring shifts.

Im done messing with it, and am hoping someone could go through everything and either A.) fix the issues or B.) confirm that the replacement is needed.
So if you are willing to do this or know someone that is let me know and name your price...
Thanks,
Zach
