Based on my experience on the Altima/Maxima CVT transmissions they have serious valve body issues. I'm sure that's not what you want to hear but the good news is there are fixes that work 75% of the time that do not require transmission removal or an new trans. Call some of your better trans shops in your area and take notes, see whom has the most knowledge. Hope this gets you on the right track.

inside the transmission.

Have the oil changed and the filter checked . I have a Mitsubishi lancer and it is in good nick but If I apply power before the shift happens it chirps the tyres . have the bands and clutch pack adjusted Run fault codes to check for faulty solenoids and servos.

check your fluid and if it's full it is the sign that it's going bad

why do you need to add fluid into trans. it is a CVT trans, which doesnt require any service unless you are towing with vehicle. its a maintenance free trans unless of course you have a leak. just to give you heads up 1qt. of CVT fluid goes for around $20 a bottle (quart).

the cvt transmissions have become a known issue, and nissan (in canada, not sure about usa) has since offered an extended warranty to 200000 KM ( 120000 M ).

I don't understand you problem, I have a 2007 maxima with CVT transmission, THERE ARE NO GEARS ! WHAT ARE YOU TALKING ABOUT? CVT = constant velocity transmission. It's like driving a golf cart.
