When I try to race the car too much like I mean on highways; if I press the accelerator full down and drive and then stop at a signal, the RPM goes up and down and the gear shifts very badly. It feels like the gear is in 3rd or something and not changing. Any idea what causes this?

Hello. It kind of sounds like a shift solenoid in or on the transmission is failing. Then the computer detects the issue and puts the car into "limp mode." When a car is in limp mode, the computer puts it in 1st or 2nd gear and doesn't allow it to shift. This allows you to drive the car to a shop without doing any more damage to it. I would suggest taking to a shop (at low speeds) and having them connect a diagnostic scanner to it. They should be able to pull a trouble code from the computer and investigate from there.
