Hi,
First, if you haven't already, I recommend having the can-bus scanned to see if there are related diagnostic trouble codes. CAN stands for controller area network.
Basically, the different modules in the vehicle are tied together via a few wires. This type of scan will retrieve codes regardless of the module storing them.
Here is a link that explains how it's done:

Also, is this the original transmission and how dirty was the fluid when you changed it? I ask because it could simply be a faulty transmission or there could be a line pressure-related issue. If you look below, I attached the tests for checking line pressure.
I've seen the transmission cooler become restricted causing low pressure. However, keep in mind with a CVT transmission, often times this indicates an internal problem.
Let me know.
