webby sti v7

hello gents my, my 01 sti v7, has a annoying problem when cold. the box can be stiff going from 2nd to 1st when just rolling and clutch engaged. when it is warmed up it is ok, but when changing from 1st up to 2nd i can actually here the gear change not crunch or grind. but you know when you change gears in a car with the engine off and the clutch not engaged, yes that sound, the car has only done 14000 miles. is it the oil type or something more sinister? heeeeeeeeeelp, webby.
