I bought an 04 sentra with an automatic transmission a couple of months ago. As it shifts from 2nd gear into 3rd it makes a noticable squeek noise. It only does this at those gears not any other time. I was wondering if anyone knows why it does this and if it is anything serious. Thanks.

Also,, if I drive it when its not warmed up, when I come to a stop the rpms will just have a quick drop then go back up. This happens as fast as you can snap your fingers and does not happen once the car is warmed up

I have a 2001 Sentra and it does it all the time warm and cold... my understanding from of it is that it could be a fluid issue or a clutch issue witht the car... People have noticed that a transmisson flush and adding a modifier that you can pick up at your local dealership should stop it.. mind you i havent done this yet.
