2012 Impreza TR580 question

[70goat]

What do the numbers below TR580GD5AA represent?

I had a similar problem where i needed to replace my valve body.

T - transmission
R - Full time AWD
58- Between pulley centres
0- CVT
G- Active torque split full time AWD CVT
D- 2.0L DOHC
5AA- specific detailed spec (5AA is 2012 year)

I still haven't found what the difference between a TR580GD5AA and a TR580DD5AA is. If anyone knows if they are compatible, please let me know.
