Issues with Range on C7
I bought the Range module to keep my 2016 C7 from switching from 4-cylinder to 8-cylinder mode and back. When driving at lower speeds as in on neighborhood roads at 35-45 MPH I feel a strange shuddering in the car. Wondering if it's still trying to switch modes or maybe it's something else. Anyone else have this problem?

Sounds like you need the triple flush for the transmission, Mobil1 Blue label.
The 'flush' really isn't for the transmission but for the torque converter's clutches that are 'grabbing' when the original ATF fluid absorbs moisture.

I didn't notice the shuddering before I installed the Range. But maybe it was there and I hadn't drive the car long enough to notice.

There is a V4 V8 indication on the forward instrument fuel range mode display. If you want to check if the Range is making the shudder, just remove it and drive the exact same way and see if it changes.
