I have a few G28-03...I know two have good 5th gear.....one is unknown & an open diff....I was told it worked fine but had crunchy synchros when I bought the car for parts..... If you want-need it as a core to scavenge from.....I'll sell it super cheap....

Thanks guys. I am unsure as to the (exact) path at this time. The reason I needed this car is because I am rebuilding the transmission for my truck as the one in there is losing a stoic battle at 240,000 miles. I have other 928s I have to finish various large and small jobs on and then they can be driven temporarily.
**** happens. But for the amount of blood sweat and pesos I have put into Leeroy, I would have thought the soul of the car would have treated me a bit better recently. Its going to sit for a while one way or another.
I see your point. The Clutch Failure(s) have been from frozen TOBs, which I am not seeing a direct correlation to, but you are using the word "harmonics" which can infer a wide range of issues.
Either way, it was very very old, and is not very very broken.
harmonics would be a series of vibrations that can cause instantaneous forces. in this case, it might have been a single force that did it in.

yeah..... a 1st harmonic!
remember my example of how the tail can wag the dog?? here is a great example of how the forces at the tire, reflected back to the driveline can be WAY more impressive! there could have been 1000ft-lbs of torque acting on the driveshaft, after the TOB locked up. the car is moving.... say in 5th and we already determined that it takes about 2000ft-lbs of torque to break the tires free.......... because it happend in 5th gear, at 2:1 , thats 1000ft-lbs on the drive line. if it happened in 2nd, a gear where 300ftlbs can break the tires free, that force wouldnt have broken the driveline.
the point here is.... too bad the short shaft didnt break instead. this becomes a $4000 part vs a short shaft of several $$hundred.
