The 1992 Ford Festiva manual transmission has a dedicated fill and check plug on the gearbox itself. You'll need to locate this plug. It's usually on the side or top of the transmission case, often with a different sized bolt head than other bolts nearby (might be slightly larger or have a different shape). It's usually a low profile bolt.
To find the fill plug:
1. Consult your owner's manual: This is the best place to start. It should clearly show the location of the fill and drain plugs.
2. Look under the car: Carefully inspect the transmission case. Look for a bolt that might be slightly different from the others.
3. Use a workshop manual or online resources: Search for a workshop manual specific to your 1992 Ford Festiva. These manuals usually have detailed diagrams showing the location of all fluid fill and drain points. Websites and forums dedicated to Ford Festivas may also provide this information.
Important: Once you locate the fill plug, use the correct type and amount of gear oil specified in your owner's manual. Using the wrong oil can severely damage your transmission. Also, be aware that you'll likely need a jack and jack stands to get proper access for this task. If you're not comfortable working under your car, take it to a mechanic.
