yours doesnt have a dipstick. It has to be checked from a fill plug on transmission from underneath the car:
Caution: Ensure that the vehicle is properly supported and squarely positioned. To help avoid personal injury when a vehicle is on a hoist, provide additional support for the vehicle on the opposite end from which the components are being removed.
Caution: The transmission fluid is hot. Caution must be taken to prevent personal injury when the transmission fluid drains from the transmission.
Notice: Saturn automatic transaxle fluid (ATF), P/N 21005966 and P/N 21019223, is not compatible with this transaxle. If Saturn ATF is used, transaxle damage will result.
Important: Before installing the transaxle level plug, apply LOCTITE Threadlocker 242®.
Tighten Tighten the transaxle fluid level plug to 12 N·m (9 lb ft).
The threaded plug is in the side of the transmission underneath the car. with vehicle on level ground and idling in park, you have to crawl underneath it and remove the plug. If transmission fluid comes out, then level is good. If none comes out, you have to add fluid thru that opening using a tube to fill the transmission fluid.
It is a pain to do this at home, but it is the ONLY way to check the fluid level yourself. otherwise you will have to take it to a shop and have them put it on a lift in the air so it can be checked.
As I said, it is a pain. you will want a helper to add fluid. Get 4ft length of 3/8" tubing put one end in the opening and have helper hold other end at hood level and he will add fluid thru that opening. It will go down the tube and into the transmission. When it starts running back out opening, pull tube out and reinstall threaded fill plug.
shops have a machine to pump it in. Unfortunately, more and more parts of the cars are being made where it is near impossible for the DIYer to take care of at home.
