I gather that this is the nature of the transmission, I don't believe this is how it should work, but the fact is that it does.
I was trying to determine whether the issue is mechanical or software related, I was thinking that if this only happened when in Auto, then it would more easily isolate software related issues. Maybe it needs to keep the RPM higher between shifts.
And so I thought if this is happening with manual shifts, maybe it's something mechanical. But I don't think that would be correct to assume, since the TCM is still involved in a manual shift.
At the end of the day, it's easy to see that this is not isolated to just a few trucks, but pretty much how it was built for all of them. It will likely be resolved through a software update and it would be nice if they could expedite the fix.
