Just reading over this forum for many months, especially the transmission segment, I got to thinking: Why do some people have so many issues with the MT especially and others not so much? Is quality control that bad at GM? Do people beat on their tranny? I have a 12 LTZ HB with the MT and it has never given me a problem. I drive like an old woman most of the time, but occaisionally I beat on it. Thoughts?
Why some bad MT's and not others

i wouldnt say some ppl have problems and some ppl dont . id say its more like some ppl deal with the transmission quirks better than others do . i love my car and would say the only thing i dont like about the car is the noise and clunkyness of the of the transmission . im not saying its bad , its just not as smooth and quiet as the japanese cars transmissions but it does the same job . i just learned to deal with it .#Doubleclutch

clutch let up is too high IMHO.
It's a factor of driving style and not being the most ROBUST tranny in the GM lineup.
For example, backing up, and then putting it in drive without letting the car come to a complete stop strains an auto tranny.
Slamming the gears in a manual, or letting your foot ride the clutch pedal are not the best ideas either..

From my understanding after researching a while on M32's used in European track cars, heat is the biggest issue. External oil tank coolers (oil reservoirs) are available from Europe, and some people have set up transmission coolers
+ pump for this reason.
The nylon shift fork covers are not conducive to high rpm shifting while hot. Brass would be better, but wear out quicker.
GM modified the case around 2011/2012 to make sure the 6th gear bearing wasn't starved of oil, a common problem on older M32's. We should all have that modified case, but few have been opened here on the forums to check. This doesn't seem to be an issue with our M32's.
Other than that, there doesn't seem to be radical differences in the synchros or rings vs other trannys. The transmissions themselves are pretty strong, a lot of people are putting big power down on stock transmissions. The new dual mass flywheel helps a lot with drivetrain shock on our cars.
... our shifter and stock cables are pretty sloppy too. There are aftermarket shifters with multi-way adjustable cable settings, that would save a lot of slop in the gear selection, but these are expensive.
