Whining noise when revving/accelerating. 2013 nissan altima

The car has been sitting for 2 weeks and when i went to start it today it made this loud whining noise from the driver side of the engine. After letting it run it went away. Now it only makes the noise when i rev the engine. Any idea what that noise could be?

Transmission’s hydrauilic pump has issues.

Something to look into.


Turn everything that’s optional and possible to turn off and still drive the car, off, and see if that makes any difference. A/C system, seat heaters, etc.
