Hi Pepperman and welcome to the board!
I'm not sure if your 5EAT has it, but supposedly the dropping resistor or duty solenoid A
can cause harsh shifting, due to higher ATF line pressure.
How many miles do you have on? Sometimes if it is cold outside, it does seem to shift harder with the ATF thicker. Yours probably takes the Subaru Idemitsu HP-ATF
. If it's due for an ATF change that might help too. I always notice smoother shifting after an ATF change if the fluid has more than about 20-30k miles on it. The fluid does degrade and lose its dynamic frictional characteristics, and that can make for harsher shifting.
The 1-2 harsh upshift does seem to be a not uncommon thing people mention about Subaru's.
