6 or 8 speed

[Wrongway2828]

Has anyone had any problems with the newer 8 speed Tranny on the 21 Cummins?
I am thinking about buying a new one and want to know if anyone has put any significant miles on the 8 speed and hasn’t had problems

I'm not up to date on the HD's, but is that even a thing yet? I knew the 6.4 got the 8 speed but I didn't hear about the SO or HO cummins getting an 8 speed?

There is only 6 gear transmissions in the cummins. There are 2 options of the 6 gear transmission for the cummins, 8 is hemi only
