Pontiac Repair: checking trans fluid level, fastener torque, automatic transmission fluid

Question
I have a 1997 Sunfire with 4sp auto transmission. There is no dip stick to check the level i the tranny. I know there is a plug in the tranny that must be removed. how do I know when it's at the proper level and what is the proper procedure to perform this check ????

Answer
Raise the vehicle on a hoist. The vehicle must be level with the engine running and the shift lever in the PARK range.
Caution: The engine must be running when the transmission fluid fill plug is removed, or excessive fluid loss will occur. Transmission fluid may be hot. Since the actual fluid level is unknown, stand clear when removing the fill plug. Have a container ready to capture any lost fluid. Do not turn the engine off with the fill plug removed, as you can be injured by hot transmission fluid being expelled out of the oil fill opening.

Remove the transmission plug.
If needed, add DEXRON®III automatic transmission fluid in increments of 0.5 qt until the fluid drains from the threaded plug hole.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Important: Before installing the fill plug, apply GM P/N 12345382  to the thread of the line pressure plug.

Allow fluid to finish draining out of the plug hole. Install the plug and tighten to specified value.
Wipe any excess fluid from the transmission with a rag or shop towel.

These are JUST sugegstions from experience and published material.
My suggestion would be to take it to a local repair facility if you have any doubt in doing this procedure.
Good Luck
