I heard a wiered noice coming from my trans so I lift it up and take off the little plate to see the converter and come to find out that one of my tourque converter bolts had broken off. Has anyone evere heard or seen this happen? And also wtf causes this to happen because I can't even imagine why this happened. Also its a 4L60E trans in a 99 bird
