* Manual Transmission: The fill point is usually on the top or side of the transmission case. It's often a threaded plug, sometimes with a dipstick integrated. Look for a plug near the top of the transmission, often near the shift linkage. You might need a wrench.
* Automatic Transmission: Automatic transmissions typically have a dipstick, often marked with "ATF" (Automatic Transmission Fluid). Check your owner's manual; the dipstick is usually readily visible and accessible in the engine bay, near the transmission. The fill point is often the same as the dipstick tube.
Crucially, consult your owner's manual. It will have diagrams showing the exact location for your specific transmission type. This is vital to avoid putting oil in the wrong place and causing damage. If you don't have the manual, you can often find a digital copy online by searching for "[Year] Ford Laser owner's manual" (PDF).
