If you have HP Tuners send me the file and I'll take a look at it. All my money is on your force motor current tables needing decreased.

I battled the identical thing as you...break-neck 1-2 shift no matter how many times i fooled with the shift pressures, etc.. Finally was able to DRAMATICALLY reduce the harshness in the Force Motor Current Tables.

Reducing (Number values) force motor current will increase firmness
