Engine/Transmission (1998.5 - 2002) 2001 6 speed won't shift - maybe hydrolic clutch???

I was driving yesterday and suddenly the truck was stuck in gear and I could not shift (the clutch would kinda engage so it would idle at a stop) if I would shut the truck off it would shift into any gear that I would choose - but once it was running that was the gear I had to use - So I drove it to the repair shop in 2nd gear -- is this a hydrolic clutch related issue - the clutch should still be good with 30K miles on it
