You need a new air flow meter and air filter. Your car ir running lean, resulting in bogging issue. I am sure, that you have been using a aftermarket air filter, which is the cause of the air flow meter failure. Is the check engine light on?? if so scan it and you will most likely come up woth "fuel system lean P0171 code" Aftermarket filters are the root cause of air flow meter failure in a sentra. Let me know what you find.

yes the transmission speed sensor has most likely failed, to confirm this have a trouble code test run

This code is a transmission code. This requires the transmission to be replace and the transmission control unit to be reprogramed. If your car has less than 60k miles this would be covered under your power train warranty.
Thanks Jay!

The Syncro is worn. Fluid will not help. I'm afraid it's time for a rebuild or another used transmission from a junkyard.

First off do not listen to Autozone, they are very quick to spend your money, they are screen readers not trained automotive technicians. No fault code with few exceptions tells you exactly what is wrong, it can be the sensor, the wiring to it or the control module (computer) that has the problem. The pressure sensor is inside the transmission a really dirty big job to access, so have a TRAINED technician look into this before any parts are replaced.

Now i dont know a lot about automatics especially modern ones with all this fancy electronics thats used nowdays but i think its a fault with the temperature sensor for the gearbox.But where its located and what it looks like i have no idea it could even be mounted inside the gearbox .Sorry not a very good answer from a mechanic but?? very few of our europeon cars come with auto transmission .Evan when i do know whats wrong i cannot buy the parts for the gearbox as only re-con boxes supplied by the dealer so best advice is to try a specialist in auto box repairs only .PS some of my best students when i used to teach mechanics many moons ago were the girls so no excuses like iam only a girl please
