In doing a search to check average hours on a gear box, I thought I'd report that I've gone 96 hours on my original gear box (997.2). I'm having it rebuilt this month. I'll be very curious to hear of it's condition.

You probably have the touch of an angel with your gearbox... MY2012 wide gears or not I have not heard of 997s lastings beyond 50-60H of competitive use... with a blipper I managed some 25H and even then the 2nd/3rd dogs were spent...

I have an estimated 55 hours on my 997.1 gearbox and upon recent inspection it was pristine. I have a blipper and use the clutch on all downshifts which may improve longevity.
^^^^This.....I always use the clutch on downshifts and have pushed the rebuilds to 55+ hours. The dogs, bearings and some gears did need to be replaced.
Porsche likes to charge a kings ransom for their proprietary bearings because they know their vendors won't sell behind their back at a reasonable price. I would be willing to bet that SKF sells that bearing to Porsche for $300-400 ea and won't sell them to anyone else.
