Where do you check transmission fluid level on 97 caddilac sts with northstar engine?
Behind the air filter box (between the air filter box and the firewall) and under the big black elbow that directs air into the engine is a small twist off cap and dip stick. This is the top of your transmission. Be careful when removing the cap and dip stick. It only takes like a 1/4 turn and then the cap shoul be able to lift straight out. The contents are not under pressure and it should be checked while the engine is idling and warm.
