1. Get Synchroshift and replace the fluid in your tranny.

2. look under Vfaq.com on Clutch pedal adjustment.

3. your synchros are fu|<ed have a nice day and drop your tranny.

4. your shifter fork is either on or off so its not that. My guess is since you ran with no tranny fluid you fuxored your synchros or your pedal needs to be adjusted because things are worn down.
