Where is the transmission fluid filler port located on the Fiesta?

The transmission fluid filler port on the Fiesta is located under the front hood, on the left side of the engine. For manual oil change (gravity drain), approximately 4 to 6 liters of fluid are required; if using an oil change machine, around 9 to 12 liters are needed. The methods for changing transmission fluid are as follows: Unscrew the drain plug at the bottom of the transmission to drain the old fluid before refilling. Remove the transmission oil pan directly to drain and refill the fluid: This method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. Use a circulation machine to change automatic transmission fluid: A smart circulation machine can dynamically change the fluid, filtering and cleaning out sludge and impurities from the automatic transmission. Hazards of not changing transmission fluid for a long time: 1. Damage to the transmission's shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Impact on the normal operation of the transmission, leading to damage of the transmission valve body.
In my spare time, I often tinker with my Fiesta. The manual transmission fluid filler port is quite easy to locate—it's usually a screw cap hole on the transmission housing, positioned toward the lower left or right side, depending on the model year. For post-2008 models, it's typically at the rear of the engine bay. When performing the task, it's best to prepare a 10mm wrench and a funnel. Clean the surrounding area first to prevent dust from entering the transmission. Don’t overlook checking the fluid level—overfilling can cause excessive oil pressure and damage the seals. I recommend checking the fluid quality every 50,000 km; if the oil turns black, it’s time for a replacement. The process is straightforward, but caution is key. Make sure to use the correct oil specification, such as GL-4 or GL-5, and don’t switch brands carelessly—last time I overlooked this and nearly had a leak.
As a novice car owner, I spent some time figuring out the transmission fluid filler port on the Fiesta. In the automatic transmission models, there isn't a dedicated filler hole—you have to add fluid through the transmission dipstick tube, located near the firewall side under the hood where the dipstick is inserted. When adding fluid, ensure the vehicle is parked on level ground with the engine warmed up for accurate fluid level measurement. Remove the dipstick, wipe it clean, and recheck the markings. It's recommended to use manufacturer-specified fluid, such as ATF+4, to avoid wear caused by mixing different types. Regular maintenance is crucial—change the fluid at least every four years to maintain smooth driving. If you can't locate the spot, refer to the manual or use mobile apps like forum galleries for reference photos.
I've been driving the Fiesta for over a decade, from the old model to the new one. The transmission oil filler port varies depending on the model. For manual transmissions, it's usually located at an easily accessible screw hole on the side of the transmission, making the operation simple without requiring professional tools. For automatic versions, you need to use the dipstick hole, which makes the process slightly more complicated. Safety first: ensure the engine is off and wear gloves, as spilled oil can harm your skin. It's recommended to check the oil level during routine maintenance and top it up early if it's low to avoid major repairs.
