For an Automatic Transmission: The transmission fluid dipstick is usually located on the passenger side of the engine compartment. It's often a long, thin dipstick with markings for "Add" and "Full". The fill location is typically the same as the dipstick tube. You'll need to check your owner's manual for the precise location.
For a Manual Transmission: Manual transmissions typically don't have a dipstick. If your Regal has a manual transmission, you'll need to consult your owner's manual for the correct fill location and procedure. This often involves removing a fill plug on the transmission case.
Important Note: Before adding any fluid, always consult your owner's manual for the correct type of transmission fluid specified for your vehicle's transmission. Using the wrong fluid can severely damage your transmission. The manual will also show you the correct procedure for checking and adding fluid.
