Tried it on both a '21 and '22 and CVTz50 won't connect with them even a little bit. I was afraid of that, the GE trannies use a different TCM from the RE series and apparently the PID language is different. For the record, I used v1.54 (latest) with a VeePeak VP11 dongle that works 100% with just about everything else. You might want to contact CVTz50 and see if they're working on an upgrade to support the GE's:
