Auroras will default to second gear when they encounter a fault code. You can try to unplug the battery to reset the codes. most likely you have serious problems that the dealer will need to address. They did this by design. Butt heads.
Do not add tranny fluid, If you overfill the tranny you can damage the wire harness inside. ( don't ask me how I know this )
your clutch packs are cooked
Is there a button to activate the overdrive on the transmission. If the button is activated and not in overdrive mode the car will never shift into 4th gear.
If your transmission is not shifting into third gear and overdrive it could be a parking pawl. This prevents the transmission from rotating.
3000 RPM
Could be low fluid,a bad sensor or transmission going bad.
Are you sure that it's third it's not shifting into, and not fourth? The transmission is designed to not permit shifts into fourth (overdrive) until the engine and transmission have warmed up a bit.
Does this vehicle have a floor shifter? With a button within easy reach of your thumb while your hand is on the shifter? Or is it a column shift, and is there a button on the end of the shift knob? If it is the floor shift model, I believe this is a light that indicates you have entered into 'manual shift' mode. Which means you can shift your automatic transmission manually from first gear through to third or fourth(overdrive). If you have this button, push it and see if the 'MANU' light goes off. If it does, you will now be operating in automatic mode and can simply put it in DRIVE and go. If you put it in DRIVE while MANU is lit, and the car feels sluggish and underpowered, it is because you are in manual mode and starting out from a stop in third or fourth gear...which would be reason enough to think your car may be lazy. Hope this helps.
The Third Shift was created in 2004.
That car is equipped with a 4R70W electronic automatic transmission through the 2005 model year, and the Overdrive OFF switch is on the end of the shift lever. Push it in to disable Overdrive, and again to re-enable Overdrive. This feature is typically only used when towing or in very hilly or mountainous terrain that would cause the transmission to "hunt" between Third and Fourth gear a lot.
Motorcycles have a ratchet shifter. When you push the shifter down or up, the shifter returns to the middle position. First gear is selected by pushing the shifter down once from neutral. All other gear selections are by pulling the shifter up. If I remember correctly the Ninja has five gears. That would mean once down for first, once up for second, up again for third and so on. To come down through the gears is the reverse, push down on the shifter to go from fifth to fourth, once more down for third, an so on. Neutral is in between first and second. With the bike in first gear, lift the shifter gently, watching the green neutral light. When the light comes on, stop lifting the shifter. Hope this helps. Don

If this is an automatic transmission, which I am assuming it is it will not work the same as a standard. Only drive it in overdrive or 1st gear.
