TCM not recognized?! - A580

Hey everyone. First time visitor here to the Dodge section of HpTuners forum. And I'm looking for some help. I've recently purchased an 06 Grand Cherokee with the 5.7L Hemi. And I'm pretty sick of the stock transmission tune, and would like to change it up.
Problem is, VCM Suite isn't picking up the TCM when attempting to read. It states "Unrecognized Controller" with the OS listed underneath. And after chosing either of EGS52/3/4 hardware variants it is still unable to read it. Always stating "Controller not supported"
What's going on here? I thought all of these vehicles had one of the EGS5X TCM variants???
It feels like I'm missing something...
Oh and yes I'm using the latest version of VCM Suite.

Cheers!

The 5.7L WK Grand Cherokee (as well as the 4.7L) has the 545RFE, the W5A580 was only used with the 3.7L V6 and 6.1L V8 WK Jeeps. So I don't think you have an EGS5x controller.
