how do i check how much tranny fluid i have left? also this lights been coming on when i take corners really fast it looks like a box with water in the bottom and an arrow pointing down, what does that mean cuz it only comes on when i take a sharp turn really fast.

Low coolant and, if memory serves, all cavaliers from that time use the same transmissions, so you don't have a dipstick. It was a "maintenance free" transmission. If you're over 100k, time to change the fluid, though.

yeah but how do i change the fluid, believe its been due for a change but i just got it not to long ago from the rents and i dont think they ever did it and the car has 206km, so an explanation on how to change would be appreciated:)
