hi guys , taking off from a set of lights this morning in 1st gear my g/box went bang , i can select and drive with all other gears and reverse apart from 1st now . I can select 1st gear but when i take foot off clutch i get a grinding noise as if it hasnt gone into gear properly can any one help with any sugestions as to what the probloem may be and also what the cost would be to fix. Its a 03 str 3ltr diesal turbo with only 100,000kms there are no other noises at all while driving or in netural in any gear thanks im in melbourne
