Transmission vacuum adjustment on w124

[jmbeam]

I have a 95 e300d that I cant seem to adjust the quality of transmission shifts. When cold and at various times the shifting is hard. Other times its nice and soft. I think I need to get an actual gauge and adjust through the port beloe the modulator.
Does anyone know where I can get a banjo nut with a hollow bolt so that I can connect this to tranny and adjust this correctly?

Any Hydraulics shop.
(They may have another name for the Banjo Bolt;Then y'all can engage in Pantomime.)

Make sure you get the Proper Diameter AND Pitch Bolt,You do not want to
"Booger Up" that opening!

Any tips on how to get the correct size? I called three auto parts shops and no luck. Do yu think the need banjo bolt would be provided in a Vacuum gauge kit?
Thanks
