6R-140 Downshifting

2016 F-350 6.7, when coasting to a stop, 3-2 shift throws you forward a bit almost like tapping the brakes. Where should I start making adjustments? I'm thinking on and off pressures.

That's usually because the solenoids are not doing there job in the transmission. They are a very high failure items on those. I would replace them instead of trying to bandaid the issue modifying the tune.

If the solenoids are going out, why does it come and go with different tunes?

No idea, you did not mention any of that in your original post.
