Vacuum is used only to modulate, (moderate) the shifting. If you remove the vacuum, by pulling the vacuum line at the transmission modulator valve, if the transmission is in good condition it will give you very harsh shifts. If your transmission is very tired, and they a get that way eventually at about 2 to 300,000 miles a rebuild or a replacement transmission might be necessary. Just make sure that your fluid and filter are as good as you think they are. A new filter and 7 or 8 quarts of brand new Dextron II can do wonders. I have also found that adding a quart of Lucas Automatic Transmission fluid has helped my transmission a lot. If you decide to add a quart of Lucas, make sure that you pull a quart of the existing fluid out first. Over filling is not good on any transmission.
