4l80e 1-2 brutal shift

03 chevy silverado SS i segment swapped a 4l80e in.
3600 stall converter with a transgo HD2 kit, All stock other wise.
Sent log and talked to transgo tech support because i figured a .100" hole in the (1-2)seperator plate was too big but they believe it is a tune problem commanding crazy high pressure after looking at the log.
I'm sure the tune is ugly, but was wondering if someone could take a look because i feel like something isnt right on the 1-2 shift. It chirps the tires on a 1/2 throttle and its just a stock lq9 pretty unpleasant.

The shift pressures are maxed out. My advise would be to start with stock pressure first.

I had a stock 2003 2500HD tune open so i copied over the stock pressures for you to try.

Thank you i will try that and report back.

Even with stock pressure tables it's gonna hit pretty hard with that shift kit.

Especially with a .100 hole in plate and if they used the Transgo accumulator springs.
