try the point where the selector arm/cables attach to the gearbox, may be loose there or has slipped from the correct position. also check the gearbox lower mount.
anything else and its a gearbox issue.
so will i need to take it to a garage and get them to check or is it something i could check???
it just feels rough when i put it into second gear, like it wont click in properly, feels like something is stopping it.
maybe im using clutch wrong???
