You should look for RPO Sticker/Decal which has list of options in your vehicle

It could be in your Glove Box or in Spare Wheel Well 

If you cannot find it then call GM to get your Build Sheet

Or

Hope someone here works with GM and can provide your with your RPO codes based on your VIN

I checked , both are the same calibration. You can double check and see that if you select option 1 what calibration you will get and compare it with option 2.

I answered on other site.
You have MW9 but you do not have VPM options

OK problem solved
Transmission updated succesfully
