My answers for JimBlake's last post a couple of pages back (just thought I'd bring the thread forward for easier tracking, hope that's okay Scott!)

OK, first thing... The reverse lock shouldn't prevent you from doing this. Turn the key 'on' but not all the way to 'start'. Now you should be able to shift into neutral without the engine running. Yes the idiot lights will be lit up. You'll need to use the clutch if the car is 'resting' against the gears. If the shifter is seized at that point, that is an important piece of information.
- - I think I noted this before but to clarify here goes: When this condition is present turning the key all the way to 'start' without starting does not change anything. Clutch depressed, key over to 'start' and the shifter will not come out of reverse (at least not with any reasonable amount of force, haven't tried getting violent with it for fear of busting something more radically). Starting motor doesn't change condition either, shifter is locked in reverse until clutch engagement or "Flintstone" start is achieved. After which lever moves freely with clutch engaged. - -
I'm trying to get you to exercise each mechanical component separately, to see which part makes the 'bang'. That's why its important to spin the transmission without moving the brakes.
So without the engine running, you can push the clutch pedal repeatedly without 'banging'? Even on mornings when the 'bang' subsequently occurs? That means its not related to the clutch hydraulics. They don't know or care if the flywheel is spinning. Should also be unrelated to the action of the pressure plate, since that's doing the same thing it would do when spinning.
- - Motor off with repeated engagement of the clutch produces no change in state, shifter doesn't release, no bang car rests in place with/without the handbrake engaged. Pedal engagement without motor on feels normal. - -
Also, it sounds like the 'bang' never happens exactly when you start the engine. That would be the first time each morning when the throw-out bearing spins.
- - Correct. "Bang" does not occur until clutch is released with motor on OR if I "Flintstone" the car to avoid the harsh "Bang" via clutch use. Motor starts normally, no discernable side effects when this scenario happens. - -
With the engine running, engage the clutch with the transmission in neutral. This spins parts of the transmission without moving any of the brake components. If this makes it 'bang' then you've narrowed it down to a transmission problem.
- - Not possible, as noted prior I cannot move shifter to neutral when this condition is present. I might leave car parked in drive with key in overnight (No, please don't ask for my address... I'll have the alarm on) and leave in neutral to see if I can get it to occur. - -
I would not expect the brakes to be seized when you park it at night. It would happen overnite with corrosion from dew or rain or ??? So when you say it rolls freely back to rest on the tranny (at night) that doesn't rule out seized brakes.
- - True, as I noted it could come down to constriction via pads or hydraulics in colder temps where the problem is more present. However, knowing that the car will freely roll down the drive when the condition is not present leads me to think it isn't as strong of a suspect as tranny/clutch. We know condition does happen when I engage handbrake and car is not resting on tranny or vice versa..

Dealer couldn't reproduce so it is difficult to proceed in any one direction (short of dumping serious $$$ at tranny/clutch diags or brake rebuilds). SAAB won't toss in any help unless dealer can diagnose.
Any input appreciated! I really want to fix this so I can keep the car. Wife is cool with getting something new but I am keen on keeping the hatch if I can.
Thanks for continuing ideas/help.
