Thanks Steve, I adjusted my Vacuum and also played around with the control cable and SHAZZAM, I now have a smooth shifting vehicle that allows the car to shift into the upper gears.

The problem I hade previously was the vacuum line from the manifold was all "gunked up" with a substance that looked like tar. Don't know what it was comprised of, but it clogged up my line and made shifting into the upper gears (3'rd to 4'th) almost impossible.
