Transmission issue??

[retx]

Ive just developed a weird annoying situation. Sometimes it seems the transmission is slipping when i first start it up. Sometimes when I put it into gear, it just sits there and doesnt even budge until I start slowly pushing the accelerator. Once Im a block away from home, its running fine. Other times, it will just snap into gear and ready to bolt off.
The second thing is SOMETIMES it will flare on 2nd to 3rd and then hunt 3rd to 4th. Other times its fine. This is mostly when im pushing it though. If i granny drive it, it shifts perfectly fine. It started after I put on a new booster vacuum hose. It doesnt happen all the time, or at the same time of day (morning or night).
Anyone have this problem before. If it were more regular, maybe I could hunt it down, but its randomness is killing me.
