I left all pressures untouched for now, oh yea, 1 last thing, I Disabled the Upshift Adaptive Learn Tables, but left the Kickdown Adaptive Learn Enable "Enabled". Just be sure to Preset the TAP cell values after reflash, but they should have been Preset when the flash was performed. Keep in mind that small changes are all that is needed, they respond very noticably to slight changes.
I had a chance to play a little more, I found once I got close to where I wanted the shift timing (feel) & re-enabled the Upshift Adaptive Learn Tables, there was little to no change in the way it shifted, I would prefer to leave the adaptives on, as it aids in shift quality consistency once you have it tuned correctly, particularily as the transmission wears.
