Transmission Drain and Fill Plug Locations

[Scientist1968]

Hi All,

 

Could you share the location of Transmission Drain and Fill Plug Locations in 2010 FFH? It will be great if you can also share the pictures.

 

Regards

Is there any particular reason you want to drain the transmission oil? There is no recommendation in the maintenance section of the Owners Guide to ever change it. Unless you have reason to suspect that it is leaking out such as seeing oil under the car, you don't need to check the quantity. There is no torque converter and the fluid just lubricates gears and bearings like in a differential. It should be maintenance free.

Thanks Fusion Hybrid Addict for the response. We changed wheel wearing. It was tough to remove, so we removed knuckle along with axle. After the axle was removed, some of the transmission fluid dripped out. I want to top the fluid up. I will appreciate any pictures or otherwise information about the location of the fill plug.

 

Best Regards

I have a 2012 MKz and have changed the transmission fluid a few times.  I only have used the Motorcraft LV.  This is as easy of changing oil.  

- Remove the front left wheel and put the car on a jack stand.

- Remove the lower plastic shield, the one that is above the axel and covers forward from there.

  Note: to remove it completely you will also need to remove the front part of the wheel well plastic liner.

- Using the former location of the inner wheel well as a reference, you will see the 5mm hex bolt.  This is the fill plug.  Remove it. 

- On the bottom of the transmission there is another 5mm hex bolt.  It is oriented like the engine oil pan drain plug, remove it.

  Note: This will have a magnet on it.  Clean it off or replace the drain  plug.

- Once the fluid drains replace the lower drain plug with a new crush washer.

- I used a funnel with a 24 inch hose to ad 5.3 quarts of the transmission fluid.

- Allow the fluid to drain until just a bit is coming out the fill hole.

- install the level plug.

- Put the plastic covers back on.

enjoy.

Why did you change the fluid? Was it dirty?

You probably know that one requirement of oil is to suspend the metal particles that detach from components as normal wear. These particles would increase component friction and shorten the life of the unit if they were allowed to come into contact with other metal parts.  Suspending these particles prevents this friction....until it doesn't.  The more particles within the oil, the less oil is able to suspend the particles.  Replacing worn oil with fresh oil goes a long way to preventing this friction. 

 

Many auto manufacturers don't require regular maintenance in order to reduce fleet maintenance requirement statistics.  BMW with their "lifetime fill" is notorious for this. If your BMW transmission goes out after 120k miles, that was the lifetime; even though the same transmission with regular service could last 2-3x as long.

Totally agree!

Normally I'd change the transmission oil every 50k miles. It's still in a good condition, however not as good as new oil.

Recommended oil change interval is between 66 to 75k miles, at which point the oil looks noticeably darker than new.

These eCVTs are not like ordinary manual or automatic transmissions. There is hardly anything to wear, no clutches, bands, belts, valves, shifters, torque converters. It's only gears rolling on continuously engaged gears. I do not think metal particles remain in suspension in oil very long. I've never heard of that function. Oil gets dirty from blow by  but the eCVT transmission fluid is not susceptible to that. It burns if hot enough but that doesn't happen in the eCVT either. This is a sealed unit that requires no service unless it leaks. Oil never wears out. Lets talk religion next.

"Much like traditional engine oil, gear oil that has been used for too long will be dark from oxidation and debris. Depending on how long it’s been since the last change, the gear oil can also have an increased, thick viscosity. If not changed regularly, the gear oil will break down, allowing friction and grinding of gear components, resulting in unnecessary wear and costly repairs."

 

Gear Oil

[lolder]

Where is the debris coming from in gear oil? Oil molecules do not break down under normal use. They can burn (oxidize) but that requires a lot of heat which is not present in the eCVT. There are very few sources of friction in the eCVT. Let's also argue what are the best boat anchors.

Can someone please tell me the part number for the 2010 Ford Fusion Hybrid (FFH) transmission fill plug? I stripped mine...
