2015 Ram 3500 review
I can now do an official report on the truck. Bottom line (at the top for your convenience) is wife and I are completely happy with our selection of the 6.4 auto. My old truck was an 04.5 CTD, SRW...

It definitely unlocks when it downshifts. You can vary the throttle and watch the rpms changes. After the downshift, if you ease off the throttle, you can see the rpm drop as the torque converter lock back up.
That does not sound right. i can see unlocking from 5-6 to save the trans from a harsh shift. 6-5 should go from lock to lock or at least a short flair before locking. Towing in fluid coupling instead of lockup causes a lot of heat generation.
I am for sure not a Gasser expert.
Probably because he's not using tow/haul it will run longer with the converter unlocked. Mine locks up immediately when in T/H with my 5er in tow from 2nd gear on through 5th. I've yet to use 6th when towing, but I'm sure the same would apply.

Almost all of the trip did not use tow/haul mode except for a few of the bigger hills in the mountains.
