It does though.. and it worked much better (for me anyway) than the software the trans controller comes with.
It didn't brick it.

I must be doing something wrong. It want let me change the file to different type when saving file so could upload.
Add .hpt to the end of the filename.

Maybe?
Have be changed back to cpm to open?

That file is set to read the speed from the ECM via CANBUS, which are how the newer versions are set up. I forgot that changed a while ago.
So, I think your issue has to be in the ECM programming like we suspected.
I've attached a stock LS3 Chevrolet Performance calibration for you to compare to, but Chevrolet Performance uses E67 modules and not the E38 you are most likely using.

Edit: I was mistaken. The TCM IS using a calculated wheel speed. The vehicle speed check box is the driveshaft RPM via CAN.
It calculates the wheel speed based on rear gear ration that is entered and the driveshaft RPM (which it is receiving via CANbus message). I see you have a gear ratio entered so I'm not sure why it isn't calculating, UNLESS the ECM is not sending the driveshaft speed signal via CAN message.
I can adjust your file to look for the vehicle speed from the ECM instead of calculating it, but I'm not sure if that will work either. Let me know if you want to try that and I'll modify your file and upload it.
Let me know if this file fixes it. (change .hpt to .cpm)

OK, I'm getting the same error. Let me see if I can work around the GM software limitation.
OK, try this one.
