I had the same problem with my Car... It is totally your syncros... the bad news is First and Second Gear syncs are not excatly servicable... you will need a new assembly... if it was 3 rd gear it would be diffrent as you can just pop it out and put a new one on... I don't even thing you can get the parts seprately. ( I couldn't ) I hope I am wrong though cause it was a expencive repair...
