I bet that hard shift is with light acceleration. The last 6R140 I saw with this problem a new valve body fixed the issue. It's been working great ever since.
Do the upgrades while you are rebuilding the valve body.
If you have a laptop, a data link cable fron USB to OBDll. Just downloaded...
Okay, I haven't had any experience myself with the problem. But, I've heard that the aftermarket HD ones have more problems than the OEM ones. This could all be hearsay.
Sounds like the valve body. Most times though they have a hard shift at town speeds.
If you have access to forscan do a trans relearn and see if that takes care of the problem. If it doesn't I'd be willing to believe it's the valve body/solenoid.
That's sounds like a lot of haze. Cold my 300/200s will have but after the engine is warm, they run clean.
Does your engine use oil between oil changes?
I want a vgt as well as compounds. lol
I'm not sure how to help with the picture problem. Are you using the button that saus attach files? If so, and it's to big, try down sizing the picture.
