What is possibly the issues with my 2009 nissan altima coupe with 105,000 miles.

What is your question?

Loud grinding noise while on gas petal. Loud air flowing sound. Car almost floating like feeling on road back and forth. Louder noise with acceleration and not shifting Only research has been done. A few people have looked at nissan altima coupe. Been told it's transmission (differential), some type of bearings (not wheel bearings), Sway bar and or links might need fixed My nissan coupe has gotten to the point where I'm driving and I don't think it's shifting at all. Plus all the other issues I listed above. I just want someone to be able to tell me exactly what's wrong and if it worth repairing. I know it definitely some transmission issues. Every review on nissan altimas have horrible transmission and steering and many other issues. There have been 4 recalls on my car but just because my Vin number doesn't come up doesn't mean it isn't a recall

What makes this problem better or worse?

Worse as it warms up
