* Automatic Transmission: The transmission fluid dipstick and fill point are usually located on the top of the transmission itself. It's a long, thin dipstick, often with markings for "ADD" or "FULL". You'll likely find it near the back of the engine, but its precise location may vary slightly depending on the specific engine and transmission combination. You'll need to consult your owner's manual for the exact location or search for a diagram online using your Mustang's VIN number or engine/transmission codes.
* Manual Transmission: Manual transmissions in the 2001 Mustang *do not* have a dipstick. They are typically filled through a specific fill plug located on the transmission case. Again, you'll absolutely need your owner's manual to locate this plug correctly. Improperly adding fluid to a manual transmission can damage it.
Crucially: Before attempting any transmission fluid work, consult your owner's manual for the exact location and procedure. Attempting to add fluid without knowing where it goes could lead to damage to your car. You also need to know the correct type and amount of transmission fluid to use, as this varies depending on the transmission type.
