Let me preface this question by saying that I understand that a big truck transmission is a totally different animal than the transmisson in our G's. That being said, can you explain why it works for truck drivers who shift through 9 to 12 very short gears with no clutch and won't work as well in the G? Heavy trucks transmission repairs are much more expensive than ours, they don't want to damage the equipment they make a living with any more than we want to hurt our beloved cars. Why is it worse for a G37? Curious...
Trucks that are carrying incredibly heavy load will need that elimination of shifting time to accelerate from a standstill/low speed.
Perhaps the very transmission is geared more optimally for clutchless shifting. Having 9+ gears means incredibly close gear ratios, which adds to the ease/usefulness of clutchless shifting

I'd say it's probably more likely that a truck transmission is built with harder metals, tougher syncros, different gear spacing, different shifter linkage, looser tolerances, etc.
Basically just that a semi transmission is built to handle the stress of clutchless shifting. Your G37 6spd on the other hand, is most definitely not.
