having a problem with my girlfriend corsa and just looking for a bit of advice from the STW massive

got back tonight and the gearstick has become very loose, I can put the car into gear, change gears and drive. When it's in gear the gearstick will move left and right without disengaging from the gear.

Anyone else had this problem, know what's wrong it and a rough guesstimate of the cost.

Cheers

Start point would be to check if one of the gear levers has popped off, you'll probably need to get under it & in the engine bay to check the linkages.
