Anyone know if this new 10 speed tranny disconnects TC Lock for long during a shift?
That is where most of the heat is generated...unlocked
It almost has to unlock in order to shift and asking in case they have solved that

I'm definitely interested in how it handles these shifts, especially downshifts when towing (not so interested in hot-rod upshifts).
Have been really surprised how different trannys downshift under load. My F150 EcoBoost's 6-spd was very quiet, smooth and fast from 6 to 5, but could clunk loudly and shake the cab down to 4.
Pulling the same trailer, the Ram CTD's 68RFE is busy and slow going from 6 to 5: the CTD revs up when the TC unlocks, then the rpms drop once it locks up. Of course the CTD downshifts less frequently than the EcoB under load but it's a lot busier when it does. I'm told this "flare" is to protect the 68RFE from all the CTD torque.
And especially with 10 gears and 9 downshifts, I too wonder how the new 10-spd handles this under load ...
