This is a pain to check ,bad idea but I did not build it.Here it is straight from GM
Transmission Fluid Level and Condition Check (Level Check)
Important: For 4-cylinder vehicles only, perform steps 3-5.
Important: Note the original position of the AIR components, if equipped.
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 ATF P/N 21005966 is not compatible with this transaxle. If Saturn ATF is used, transaxle damage will result. This transaxle uses DEXRON® III ATF P/N 21019223.
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).
Important: For 4-cylinder vehicles only, perform steps 11-14.
Important: The clamp must be installed with the locking portion facing down.
Important: There is a stand-off clip between the A.I.R. tube and the wiring harness at the front of the transaxle. This must be in place to eliminate the possibility of chafing between the tube and the harness.
