Help?

So...I think the tranny is slipping..I'll be driving down the highway..and once I get up to about 55-60, it feels like it drops out of gear and the engine shakes REAL BAD..and when I gas it, it'll slowly go up, but my RPM's will stick to like ~2k(wherever they were) and wont move until I depress the gas heavily.
