I thought I would get an answer.

 

my dad's 04 cavalier has no dip stick, and the book says not to change fluid/filter unless you do heavy towing

 

You have not asked a question. If you want some one to confirm your statement then try this forum.

how to check tranny fluid and do a fluid and filter replacement on an 02 Explorer

 

If your tranny doesn't have a dipstick it should have a large drain plug in the pan with a check plug which is located in the center of the drain plug. Holding the drain plug with the proper size wrench so as not to loosen the drain plug, proceed to remove the check plug with the proper size Allen wrench. If the transmission is operating at the proper fluid capacity the transmission fluid should just trickle over the stem and out through the center of the drain plug. In the event that no fluid is released, this is a good indication of low or improper fluid levels.
Installation of new fluid: To install new fluid in the transmission, locate the (Fill Plug) in the extension housing of the transmission, the plug is identified by instructions for transmission fluid application.
