'05 colorado reverse gear

'05 colorado is stuck in reverse gear. Truck was cold. Started it up, put it
in reverse, backed out of the driveway and now I cannot get it out of reverse
into any other gear. Clutch seems to work fine. No indicator lights or idiot
light s on. No smells, no noises. Everything seems normal except it is stuck
in reverse. Anybody had this problem??? ledman.
