Hi all I purchased a 2.2 vectra glsi last june from Vauxhall. Until now have had no problems, have now been getting a management light warning on dashboard,took to Vauxhall dealer who said it was the gearbox sensor cost 176.22 to replace. 3 days later the light came back on took it back and have now been told that the radiator coolant has gone into the gearbox and will now need a new gearbox and radiaor total cost 2,265 pounds. Has anyone heard of this problem before. Any advice greatly appreciated. Dereck
