Default Anybody here shift clutchlessly?

I've noticed these cummins like to shift w/out the clutch; its still rather smooth and the transmission doesn't dislike it. So i've been doing it the past few days to save on clutch. Do a lot of you guys do it in these?

Are you kidding? I'm not even brave enough to try something like that....
Sounds reckless.

Reckless? Hardly. Thats how pretty much 99.99% of big rig drivers shift

Match the rpms right and you can hardly tell there isn't a clutch involved.

i call it powershifting. its nice to do. i did it a lot in my old dmax but ive heard its not the best for a trans in a pickup. pickup trans dont have the same synchronizers as a trans in a semi. somebody correct me if i am wrong.
