Ok another update for everyone so we found some vacuum leaks, one of the lines going into the cabin had such a bad leak there was no vacuum going to the transmission. Plugged that cabin line off and bypassed a leaking control box on the emission system, also found a very small leak in the ignition cutout circuit, but will resolve that later because now the car will shut off under its own vacuum system and does not need to be manually shutoff.

However upon further investigation I found the vacuum modulator on the side of the transmission is leaking and it is hissing and losing vacuum, I have a spare to replace it but hopefully that will take care of the shifting issue. The Vaccum at the modulator was around 8-9HG of mercury and the VCV was bleeding it off when the engine was accelerated so the VCV is fine. The vacuum at the brake booster was 22HG of mercury, so that was fine as well. Will report back with more results later!
