Whenever you have time Matt...
I do have a couple questions. Is the softer shifting going to reduce the life of the trans? I have read that the hard shifts are actually better for the trans and help longevity. Also, will the custom tuning allow for the trans to be programmed to lock the torque converter in fourth like it does in Tow/Haul? It would be nice for driving gravel and slow backcountry roads.
We don't have it softened at WOT; only at very low throttle input. The desired slip times are still very low, there won't be any accelerated wear from the shifting tweaks.
As for the lockup scheduling changes, yes, you'll have control of 5th gear (I'm referring to 4th as "5th", since the computer doesn't see or use 4th for most intents and purposes.). You'll also have adjustment capacity for 6th (5th).
Keep in mind that despite these being a "5" speed, the shift scheduling is 1-2-3-5-6 in reality; 4th is skipped. Please assume that any references I make are with that in mind.
