mart sti v3

pulled into petrol station yestarday and could not get into 2nd gear!!! it just wouldnt have any of it. when i left first and i really had to give it some force to get it into second gear. no crunching or anything just really tight?? seems ok after that.
has anyone else had this happen and is it the start of something about to give up

my second gear is a bit stiff in he mornings and has a notch every now and again when warm. gonna try some castrol syntrax in the box as that is what everyone recomends. you could try that.
