Hope this is the right place for this question, but I have a 2009 Nissan Sentra with 160k miles.

I’ve noticed whenever it snows my CVT shutters/slips at least a handful of times during my commute. Only happens during snowfalls.

ive Had my trans fluid changed about 30k mi ago, and am going to book another one soon but even changing the fluid hasn’t helped.

any ideas on what the issue could be? It’s becoming very irritating.
