update, i got the car back yesterday
!
final verdict is that the output back bearing broke, allowing the shaft to fall and wedge in the gears. the Why is less clear.....
three possibility's that we can think of:
1 bearing wore out (this is the typical bearing to go on these transmissions from what I hear).
2 Pulse and glide put pressure on the shaft and bearing in the opposite of normal causing it to break after ~34,000 miles of aggressive P&G and ~60,000 of kill switch use at stops....
3 some defect in the bearing
The three people at the shop cannot agree on the cause.... I could see the P&G having loaded the bearing differently but It took 34K miles to show the issue... whats my risk now? I tend to think this bearing is the weak link in the drive train and the P&G did nothing more then help hasten its death at worst. Any other thoughts?
