Where is the transmission dipstick located on a 1998 Chevy Cavalier z24?

If it is a standard, it's down on the back side of the engine. if you stand in front of the car open the hood. on the right side below the brake fluid reservoir you will see a small white stick . Lift it and pull it up. It's hard to reach and may be dirty as well; try to wipe of any excess dirt before you pull it. To top it up you need a funnel and a hose and some GM synchromesh fluid.
