Welcome to Automotive Forums. Sounds like the shifting sychronizers are bad or the hydraulic clutch may not be releasing to shift gears. Also, the hydraulic clutch may need to be bled to get the air out of the line going to to the transmission. If it did this on only 1 particular gear it would probably be the synchronizer but if it does it on all gears it is the clutch not releasing. Having it bled to get the air out and to get a good pedal may work. If it doesn't work you will probably have to put in a new clutch master cylinder or slave cylinder at the tranny. I think the clutch master cylinder uses the same reservoir for fluid as the brake master cylinder. Check the fluid in the brake master cylinder. It is on the firewall of your car on the left hand side as you are sitting in the car.
