Is the pilot bearing shot in my '94 Celica?

I own a ‘94 Toyota Celica and I had a new clutch kit put in it about 12 months ago and about a month ago it started developing a problem which I was told was possibly a pilot bearing. The symptoms are that the car won’t shift into third gear, idles a bit high, has a high-pitched whine when driving and a bit of a burning smell that doesn’t smell like a fluid but more of a metallic burning. Can anyone confirm if this might be the pilot bearing or might it be something else?
