Was just wondering if anybody has any idea on how this could have happened. I did not feel any bad vibration while driving. I was going around a 100 mph when I went to hit 3rd gear and than BOOM! I was very very very lucky it did not catch on fire and the drive shaft stayed on. My engine only makes 481 HP and 440 TQ. The tranny was stock. Im just kinda nervous about putting another stock tranny in. Thanks for any help.
