Wow just wow. Towing in overdrive has nothing to due with the torque converter. It has to due with the power band of the engine and constantly down shifting which creates excessive heat. Also overdrive clutches are smaller in diameter and are deisgned to take less torque.
Just a side note I...
Ride the torque converter like riding a clutch really! They work completely different a torque converter is designed to slip. They lock up via hydraulic pressure when the tcm commands it too.
Now on to the real question, yes our trucks could be programmed to start in second. But that would...
My guess is it had something too due with FCA going away from Pennzoil and lowering maintenance costs. Personally I switched to 5W-40 myself before the change with no noticeable change.
