Where is the transmission dip stick on 2004 cavalier?

Answer 1

Here is how Chevrolet suggest checking fluid.

Start the car and allow it to idle for 10 mins or until it is at normal operating temperature. Then, starting in park, go through all the gears and see if it shifts smooth. If it feels ok then it should be good, but if you have reason to believe that the fluid is low then it is suggested that an experienced mechanic check your fluid. The process is a bit dangerous but I will post it so you can take a stab at it if you feel you are experienced enough. Raise the vehicle and ensure the car is level to give an accurate reading. The car must be running and at normal operating temp. the check plug is located in the front right corner of the drain pan near the engine oil drain plug. The fluid should be just at the bottom of the peep hole, if it overflows alot then it is too full and if it does not come out at all you need to add a small amount of fluid.

Use DEXRON III tranny fluid.
