is the selecton problerm from 1st to 2nd or 1st and 2nd gear ? does reverse select ok ? does the it engage nicely with the engine switched off ? if its 1st to 2nd and crunches sounds like a sincro . if its 1st 2nd and reverse but goes in ok with the engine off it could be the cluch not clearing or a master or slave cylinder problem . if it just has poor selection with engine on of off sounds like the cable is out of adjustment poss streched or part of the linkage could be worn or loose my shift weight on the gear box came loose and i had really poor gear change . anyhow i hope this might
