2013 Nissan Sentra SV Transmission not shifting properly when cold

I'd say that's probably the first think to do/check. After doing a search on the internet for the same car and same issues I've discovered that this is a problem with Nissan CVT Transmissions. Other people's stories are that they be cruising down the road and all of a sudden the motor revs high but the car loses power scaring the hell out of them. Of course the majority of them are out of warranty & I've read where people have had to pay as much as $4,500 to have their transmission replaced. One person said after replacing theirs it went out again 2 years later. Now I know why I haven't seen Nissan commercials bragging about their "smooth-less shifting" of their CVT Transmissions.
