Sounds like one of the forward gears has a bad needle bearing
. The only way to find out which gear it is is to try to take off in each forward gear. The gear that is locked in might be hard to shift into and the car should move (1st or 2nd will move easily, 3rd/4th/5th probably won't move the car easily) normally depending on what gear it is. Engaging 2 gears at once will lock the transmission and the car will not move at all. At any rate, you will need to have the trans rebuilt or replaced.
