I went to get gas last night a few miles away and was running it through the gears coming back when it went "bang" at the top of third gear. I thought it was the driveshaft at first, but smelled burning trans. fluid and saw a cloud of white smoke behind me. I pulled over and looked under and found the tailshaft housing had broken in half! I did have 4 adults in it all Wednesday night and an extra 120 lbs. in the trunk so I wonder if the driveshaft might have bottomed at some point and weakened the housing?
