Transmission Adaptives Timeframe
When loading a brand new transmission tune to a 6R140 equipped truck, how many miles would you assume it should take for the transmission to "learn" your driving habits and smooth out the shifts?
I asked for and purchased a tune from Xtreme Caliber that was supposed to include 100% stock Ford OE transmission programming. I loaded it last night, drove the truck today about 40 miles. It's shifting FIRM in all gear changes. Not quite banging, but close. I do not remember the truck shifting like this at all when I bought it. It shifted almost sloppy, almost too soft.
What I'm wondering is... did they NOT send me a factory stock trans calibration? Or does it just take a long while for the TCU to learn and smooth out and I just need more miles on it?

I'm no expert but I am running a trans tune on my 10R140. It's been smooth since the minute I loaded it. It's my understanding the tune turns off adaptive learning. Maybe it's your tune? I can choose from a multitude of tunes from stock to high pressure, high shift points, no skip, etc.
And maybe your stock tune isn't stock?

sounds like it's your tune. although my 250 had crispy shifts when it was new off the lot
when i did weight loss, the GDP tune was trash, they told me to drive it a hundred miles or something, and it was unbearable and felt like i was going to nuke the trans. the first drive with the new tune from another company it was PERFECT. no time to re learn or anything.

So they e-mailed me back and said they accidentally sent the wrong tune file. It all makes sense now! 
They have now sent the correct file.
It's a good thing I had a mental reference for what the OE tune feels like or else I may have never known something was awry.
