* Automatic Transmission: The dipstick is usually located on the transmission itself, often near the back of the engine compartment. It's frequently a long, thin dipstick with markings for "ADD" and "FULL". The fill location is often the same as the dipstick tube. Check your owner's manual for the exact location.
* Manual Transmission: Manual transmissions typically don't have a dipstick. The transmission fluid is checked and filled through a separate fill plug, often located on the side of the transmission case. Again, consult your owner's manual for the specific location and procedure. This is more involved and often requires removing a bolt.
Strongly recommend checking your 1996 Chevy van's owner's manual. It will have diagrams and clear instructions for locating the correct dipstick or fill plug, and the proper procedure for checking and adding transmission fluid. Using the wrong fluid or filling it incorrectly can severely damage the transmission.
