* Automatic Transmission: The transmission fluid dipstick is usually located on the passenger side of the engine compartment, near the transmission itself. It's often a long, thin dipstick with markings for "ADD" and "FULL." The fill location is usually the same as the dipstick.
* Manual Transmission: Manual transmissions generally don't have a dipstick. They usually have a fill plug on the side of the transmission. You'll need to consult your owner's manual or a repair manual to find the precise location of the fill plug. Adding fluid to a manual transmission is less common as it's usually a sealed unit unless there's a leak.
Important Note: Before attempting to check or add transmission fluid, consult your owner's manual for the exact location and procedure. Improperly adding transmission fluid can damage your transmission. If you're unsure, it's best to have a qualified mechanic check and service your transmission.
