sounds like a seal or somethin may have broken, if not the casing has got damaged, have you had a look for holes? for a 6 speed you'd need to supply them with your existing case...so if its damaged , you'll have to get anothe box from somewhere. what was the steering like? did it feel heavy? reason i say that is its common for the diff to let go and take the 'box with it. there is a '93 vr6 at a breakers somewhere (contact details are on a thread titled 'i've joined justins club' or similar), but they wanted £60 for the set of clocks, so they may well ask loads for the box.
