Well first of all you have to go through a specific, detailed diagnosis procedure which would need to be done by a licensed mechanic. It isn't something you can just guess at and fix in your own garage, in my opinion.

Some ideas of other possibilities: there is a "stop" sensor in the brake assembly, and if it goes bad the TCM gets very confused and won't select a low gear ratio, this occurs occaisionally with Nissan's so this is a possibility, and if this is the problem it would be much less serious than replacing the entire TCM or CVT transmission itself. The TCM is the "transmission control unit", it is a computer that works with ECU engine control unit to select throttle and CVT gearing based on thousands of always changing inputs. Often TCM issues can be solved with a reflash, or reprogram, you don't always necessarily have to relace the whole unit.

Anyway, what I'm getting at is that you need a lot more information to properly determine what's happening. But a test to determine if you brake stop sensor is working is to push on the brake and have someone check if your rear brake lights come on, if not, then you may have bad sensor which isn't such a serious repair.

But basically you're going to have to take it to the dealer and let them properly diagnose and repair your problem.
