GSR auto vs LS Auto tranny

[JKOBD]

jdm gsr is 37820-P72-901 still trying to confirm this.

Yeah, that is the part number for the ECU. I have a couple of those at my house as well as a couple B16 autos too. The problem is that I need the mission assembly part numbers. The auto LS part number for OBD2b is 20021-PGA-A10. I know the 20021 prefix is for automatic transmissions. Just as the 20011- prefix is for manual transmissions. 37820 is the prefix for ecus., etc.

So I searched through the 20021 prefixes and um yeah....there are over 2000 combos...lol. So I am going to continue searching for the middle number identifying the GSR/B16. I have confirmed the AUTO LS gear tooth count already.
