ok it seemsto take a long time for it to change from 1st to second then when it changes from 2nd to 3rd it has a vibration in it. not a tailshaft vibration but within the gearbox. the gear box also make a wynding noise i thought it was my diff but it sounds as though it is coming from the gearbox. when the rear end is on jacks and you put car into drive you can hear the wynd coming from the gear box. do i need a new box ??? or is it worth getting it fixed....
